Abstract

PURPOSE:To obviate the decrease in surface area and to obtain a bright color display by forming the transparent electrodes formed in correspondence to color filters to the width slightly larger than the width of the color filters. CONSTITUTION:The color filters 2 of three primary colors are formed on the opposite surface of a transparent substrate 1. A black matrix 3 is formed between these color filters 2. The color filters 2 and the black matrix 3 are coated with an org. film 4 consisting of a top coat and the transparent electrodes 5 are formed thereon. Further, an oriented film 6 is formed on the transparent electrodes 5. The oriented film 6 is subjected to an orientation treatment. The transparent electrodes 8 are formed in correspondence to the color filters 2 on the opposite surface of a transparent substrate 7 provided to face the transparent substrate 1. These electrodes are formed to the width A slightly larger than the width C of the color filters 2. The display area of the color filters 2 does not change even if the transparent electrodes 1 and the color filters 2 deviate and, therefore, the bright color display is obtd.

Description

[Detailed description of the invention] [Industrial use separation] ``Himiri'' relates to color liquid crystal elements.

[Conventional technology]

As described in Japanese Patent Application Laid-Open No. 62-240933, a conventional color liquid crystal device has three primary colors of red, green, and blue on one of two transparent substrates on which transparent electrodes are formed. A transparent electrode on the other transparent substrate facing the transparent substrate on which the filter is formed and the color filter is formed is formed corresponding to the color filter.

[Problem to be solved by the invention]

The above conventional technology does not take into account the relationship between the transparent electrodes formed corresponding to the color filters and the color filters.If the transparent electrodes are misaligned with respect to the color filters, the display area becomes narrower and the transmittance decreases. There was a problem in that the display became dark.

An object of the present invention is to provide a color liquid crystal element that prevents a decrease in display area σ) and provides bright color display.

[Means to solve the problem]

In order to achieve the above object, the width of the appropriate electrode formed corresponding to the color filter is slightly wider than that of the color filter.

[Effect]

If the width of the transparent electrode corresponding to the color filter is formed to be slightly wider than the color filter, the overlapping area of the transparent electrode and the color filter will not change even if the transparent electrode is misaligned with respect to the color filter. Since the appropriate area for light is to be changed by this, the transmittance does not decrease.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. Red (R), green (G),
Color filters 2 of three primary colors of blue (B) are formed, and a blank mask 3 is formed between the color filters 2. The color filter 2 and the blank mask 3 are covered with an organic film 4 made of a top coat, and a transparent electrode 5 is formed on the organic film 4. An alignment film 6 is formed on the transparent electrode 5, and this alignment film 6&'i is subjected to an alignment treatment.

An eye 5 is formed on the opposite puff 1 side of the other transparent substrate 7 provided opposite to the transparent substrate 1, and a transparent electrode 8 is formed in contrast to the previous color filter 2. Here, Tooru 1.”
The width A of the electrode 8σ is slightly larger than the width C of the color filter 2. An alignment film 9 is disposed on the transparent electrode 8.
is formed, and this alignment film 9 has been subjected to alignment treatment.

A liquid crystal material is inserted between the thus shaped transparent substrates 1 and 7 to form a liquid crystal base 10.

As shown in σ), the transparent electrode 8 has a phantom ratio of 11111'l A &j2 to the color filter 2, and θ) is slightly thicker than the width C of the color filter 2 and is set to 31>+ノν. Since the transparent electrode 8 is wider than the color filter 2 and the bright electrode 8 or 8, the area between the color filter 2 and the transparent electrode 8 remains the same.

Therefore, since the amount of light σ) transmitted does not change, a color liquid crystal element with a narrow display can be obtained. For example, C2901L
In the case of m, when A-=100PmVC, the alignment accuracy was ±5 #Lm, and excellent results were obtained.

2nd L=]+w shows another embodiment of the present invention. The above example is -Noiσ) Gauze 11JII Iita IK color filter 2
, and on the other diversion plate 7, transparent 1iJ corresponding to color filter 2, 3 with 4' tunryu 8 formed, and Honji 11.
In this example, a color filter 2 and a transparent electrode 8 corresponding to the color filter 2 are formed on one transparent substrate 1. and,
The transparent electrode 5 in the above example was formed on the other transparent group; Even if formed in this way, the same effects as in the embodiment described above can be obtained.

[Start σ] Effect] According to the present invention, even if the transparent electrode and the color filter are misaligned due to assembly work, the display area of the color filter does not change (I), and the light transmittance does not decrease (, A bright color display can be obtained.
