Description

  The present invention relates to an organic EL (Electro Luminescence) device that emits light in a line shape. The present invention also relates to an organic EL module that incorporates the organic EL device and is mainly used as illumination.

  In recent years, organic EL modules have attracted attention as a lighting device that can replace incandescent lamps and fluorescent lamps, and many studies have been made.

Here, the organic EL module is obtained by applying a sealing structure and a casing to an organic EL device. In addition, the organic EL device is formed by laminating an organic EL element on a substrate such as a glass substrate, a transparent resin film, or a metal sheet, and forming a power feeding structure for feeding power to the organic EL element.
And an organic EL element makes two electrodes which one or both have translucency oppose, and laminated | stacked the light emitting layer which consists of an organic compound between this electrode. The organic EL device emits light by the energy of recombination of electrically excited electrons and holes.
That is, the organic EL module is a self-luminous device and can emit light of various wavelengths by appropriately selecting a material of the light emitting layer.

  In addition, the organic EL module has a feature that the thickness is extremely small and lighter than incandescent lamps, fluorescent lamps, and LED lighting, and light is emitted in a planar shape. Furthermore, since the organic EL module has higher luminous efficiency than incandescent lamps and fluorescent lamps, the organic EL module has features that it consumes less power and generates less heat.

  By the way, in recent years, lighting devices for living spaces are required not only to function as simple lighting but also to improve the design of living spaces. For example, in order to make the living space look fantastic, a lighting device may be installed in a part that forms the outline of the living space such as a boundary part between a ceiling and a wall surface. When emphasizing the outline of such a living space, a lighting device that emits light in a line shape is often used.

As a technique for emitting light in a line shape using an organic EL module as a light source, for example, there is a technique described in Patent Document 1.
In the organic EL element of Patent Document 1, an anode thin film (electrode), a light-emitting organic thin film (light emitting layer), and a cathode thin film (electrode) are formed on a transparent substrate. By patterning, a line-shaped light emitting surface is formed. Further, the organic EL element of Patent Document 1 uses an end portion in the longitudinal direction of the anode thin film itself as an anode thin film terminal portion, and uses an end portion in the longitudinal direction of the cathode thin film itself as a cathode thin film terminal portion. And the organic EL element of patent document 1 is equipped with the electric power feeding structure which connects an external power supply directly to these anode thin film terminal parts and cathode thin film terminal parts, and light-emits a light emitting organic thin film.

However, in order to use the technique of Patent Document 1 for a lighting device in a living space, it is necessary to increase the length of the entire organic EL module in the longitudinal direction as compared with the organic EL element described in Patent Document 1. is there. That is, when the technique of Patent Document 1 is used as a lighting device in a living space, the distance from the anode thin film terminal portion to the end of the anode thin film becomes long, so that no current flows to the end of the anode thin film during driving, and the entire area is even. May not emit light. Moreover, even if the current spreads to the end of the anode thin film, there is a possibility that the current density of the current passing between the anode thin film terminal portion side and the end of the anode thin film is different, resulting in a difference in luminance.
In the first place, in the case of the organic EL element of Patent Document 1, the anode thin film is formed of indium tin oxide (ITO). In general, ITO has a high contact resistance, so when connecting an external power supply directly to the anode thin film terminal, the voltage drop (so-called IR drop) is large, and it is necessary to apply an extra voltage in order to sufficiently energize. is there. That is, the organic EL element of Patent Document 1 has a problem that current is less likely to reach the end of the anode thin film.

The electrode connection grooves 27 and 28 are each formed in a region of 1/3 from the long side of the substrate to the short side of the substrate. The functional layer 15 is divided into three sections by the electrode connection grooves 27 and 28.
On this substrate, the functional layer 15 is present except for the electrode connection grooves 27 and 28. Therefore, the laser scribing process can be used in this way, and the mask process for hiding the film formation surface on which no film is formed can be omitted when the functional layer 15 is formed.

In addition, the second electrode layer 16 is present on the substrate except for the light emitting element isolation groove 23. Therefore, the laser scribing process can be used in this way, and the mask process for hiding the film formation surface on which the film is not formed can be omitted when forming the second electrode layer 16.

Next, a part of the substrate is covered with a mask, and the insulating layer 17 is formed by a CVD apparatus. Specifically, when the organic EL device 2 is formed, the positions corresponding to the exposed regions 25 and 26 are covered with a mask to form a film (FIGS. 6G to 6H).

The power feeding unit cover 51 of the conductive member 3b is in contact with the cathode power feeding unit 36 (see FIG. 3) located in the exposed region 26 of the organic EL device 2. The end surface covering portions 52 and 52 of the conductive members 3a and 3b are in contact with the end surface of the organic EL device 2, and the substrate covering portions 53 and 53 of the conductive members 3a and 3b are the first power supply region 31 and the second power supply region. A part of the substrate 11 in 32 is in contact.
As shown in FIG. 7, a predetermined interval W2 is provided between the tip of the substrate covering portion 53 of the conductive member 3a and the tip of the substrate covering portion 53 of the conductive member 3b, and the interval W2 corresponds to the opening 60 of the frame body 5. It is larger than the opening width W1 (see FIG. 5).

  Further, paying attention to the longitudinal direction l, one end of the conductive members 3a and 3b in the longitudinal direction 1 projects from the organic EL device 2 to form projecting portions 55 and 55. That is, the overhang portions 55 and 55 that are one of the tip portions of the conductive members 3a and 3b are free ends. The opposite end is flush with the end face of the organic EL device 2.

Thereafter, the frame 5 is attached to the organic EL device 2 and the conductive members 3a and 3b which are integrated as shown in FIG.
At this time, paying attention to the width direction w, the element-side cover 61 of the frame 5 covers all the upper surfaces of the organic EL device 2 and the conductive members 3a and 3b. That is, the element-side cover 61 of the frame 5 covers the power supply portion covers 51 and 51 of the two conductive members 3 a and 3 b and the insulating layer 17 of the organic EL device 2. The end surface covering portions 62 and 63 of the frame 5 cover the outside of the end surface covering portions 52 and 52 of the conductive members 3a and 3b. The light extraction side cover portions 65 and 66 and the damming walls 67 and 68 of the frame 5 involve the substrate cover portions 53 and 53 of the conductive members 3a and 3b, so that the substrate cover portions 53 and 53 are exposed to the outside.

When attention is paid to the longitudinal direction l, as shown in FIG. 1, a connecting recess 72 is positioned on the overhang portions 55, 55 of the conductive members 3a, 3b, and at the opposite end of the conductive members 3a, 3b The convex part 71 has covered.
Paying attention to the vicinity of the end on the connection recess 72 side, the protruding portions 55 and 55 of the conductive members 3 a and 3 b are partially exposed to the outside in the connection recess 72, and other portions are the rest of the frame 5. Covered by the end face covering parts 62 and 63. That is, the overhang portions 55 and 55 of the conductive members 3a and 3b are exposed in the vertical direction, and the overhang portions 55 and 55 of the conductive members 3a and 3b are not exposed in the width direction w.
On the other hand, paying attention to the vicinity of the end on the connecting convex portion 71 side, the power feeding portion covering portion 51 of the conductive members 3a and 3b is hidden inside the connecting convex portion 71 of the frame 5, and the end faces of the conductive members 3a and 3b The covering portion 52 is exposed from the end surface covering portions 62 and 63 of the frame body 5.

To. The current reaching the second electrode layer 16 is transmitted to the external power source through the conductive member 3b that contacts the exposed region 26. In this way, a current flows through the functional layer 15 and the functional layer 15 emits light and functions as illumination.

Subsequently, a connection example of the organic EL module 1 will be described.
As shown in FIG. 26, the connecting convex portion 71 of the adjacent organic EL module 1A and the connecting concave portion 72 of the organic EL module 1B are fitted.

  According to the configuration of the present embodiment, the anode power feeding portion 35 and the first electrode layer 12 are fixedly connected within the electrode connection groove 27 in the first power feeding region 31. Further, the anode power supply unit 35 employs a contact resistance lower than that of the first electrode layer 12 and a lower internal resistance. Therefore, even when an electrode having a large contact resistance such as ITO is used as the first electrode layer 12, it is the anode power supply unit 35 that directly contacts the external power source, and therefore the external power source is directly connected to the first electrode layer 12. The contact resistance can be reduced as compared with the case of connection. Therefore, it is not necessary to apply an extra voltage, and power consumption can be suppressed.

Further, the cathode power feeding portion 36 employs a material having a peel strength (adhesion force) with the first electrode layer 12 larger than that of the functional layer 15. Therefore, the peeling strength (adhesion) of the functional layer 15 with respect to the first electrode layer 12 is assisted by the peeling strength (adhesion) of the cathode feeding portion 36 with respect to the first electrode layer 12. 36 from the first electrode layer 12 can be prevented.
Similarly, also in the first power supply region 31, the anode power supply part 35 and the first electrode layer 12 are fixedly connected in the electrode connection groove 27. In addition, the anode feeding portion 35 employs a material having a peel strength (adhesion force) with the first electrode layer 12 larger than that of the functional layer 15. Therefore, it is possible to prevent the functional layer 15 and the anode power feeding part 35 from being integrally peeled from the first electrode layer 12.

  According to the structure of this embodiment, it has the electroconductive members 3a and 3b which cover the whole longitudinal direction of the exposure areas 25 and 26 of the organic EL device 2, and spreads in a planar shape from the external power source via the electroconductive members 3a and 3b. Therefore, the current is uniformly input from the anode power supply unit 35, and the current is output from the cathode power supply unit 36 while spreading in a planar shape, so that light can be emitted without luminance distribution in the longitudinal direction.
