Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a liquid crystal display (LCD)

The present invention relates to a liquid crystal display, and more particularly to a liquid crystal display capable of easily removing unnecessary charges such as static electricity.

Generally, the driving principle of a liquid crystal display device utilizes the optical anisotropy and polarization properties of a liquid crystal. Since the liquid crystal has a long structure, it has a directionality in the arrangement of molecules, and the direction of the molecular arrangement can be controlled by artificially applying an electric field to the liquid crystal.

Therefore, when the molecular alignment direction of the liquid crystal is arbitrarily adjusted, the molecular arrangement of the liquid crystal is changed, and light is refracted in the molecular alignment direction of the liquid crystal by optical anisotropy, so that image information can be expressed.

At present, an active matrix liquid crystal display (AM-LCD: hereinafter referred to as liquid crystal display) in which a thin film transistor and pixel electrodes connected to the thin film transistor are arranged in a matrix manner has excellent resolution and video realization capability, It is attracting attention.

The liquid crystal display device includes a color filter substrate on which a common electrode is formed, an array substrate on which pixel electrodes are formed, and a liquid crystal interposed between the two substrates. In such a liquid crystal display device, The liquid crystal is driven to have excellent properties such as transmittance and aperture ratio.

However, liquid crystal driving by an electric field that is applied up and down has a drawback that the viewing angle characteristic is not excellent.

Therefore, a transverse electric field type liquid crystal display device having excellent viewing angle characteristics has been proposed to overcome the above disadvantages.

1 is a cross-sectional view schematically showing a liquid crystal panel of a general transverse electric field type liquid crystal display device.

As shown in the figure, the array substrate 10 and the color filter substrate 20 face each other with a space therebetween, and a liquid crystal layer 30 is interposed between the two substrates 10 and 20.

The first and second polarizers 40 and 50 are attached to the respective outer surfaces of the array substrate 10 and the color filter substrate 20 and the light of the first and second polarizers 40 and 50 The transmission axes are arranged to be orthogonal to each other.

At this time, a common electrode 12 and a pixel electrode 14 having a bar shape are formed on the first substrate 10. A horizontal electric field L is formed between these two electrodes and the liquid crystal molecules 31 of the liquid crystal layer 30 are aligned with the horizontal electric field L, that is, the common electrode 12 and the pixel electrode 14, As shown in FIG.

As described above, in the transverse electric field type liquid crystal display device, the common electrode 12 and the pixel electrode 14 are formed on the array substrate 10, and a horizontal electric field L is generated between these two electrodes 12 and 14, The viewing angle of the liquid crystal display device can be widened by arranging the liquid crystal panel 31 in parallel with the horizontal electric field L parallel to the array substrate 10.

However, in such a transverse electric field type liquid crystal display device, unnecessary electric charges such as static electricity tend to flow into the color filter substrate because no metal or conductive component is formed on the color filter substrate. In this case, The operation characteristic is deteriorated.

Therefore, in order to solve such a problem, as shown in Fig. 2 (sectional view of a part of a conventional modularized transverse electric field liquid crystal display device), a transparent conductive metal layer 60 is further formed on the outer surface of the color filter substrate 20 One end of a conductive tape (not shown) is attached to a portion of the transparent conductive material layer 60 and a part of the non-display region of the color filter substrate 20 exposed to the outside of the second polarizing plate 50, And the other end is attached to one of the ground, the top cover 70, and the cover bottom 75 provided on the external driving circuit substrate (not shown), which is a component of the liquid crystal display device, to ground the static electricity Is grounded and discharged to the outside.

However, in the case of the conventional transverse electric-field liquid crystal display device 1 having such a configuration, in order to attach the conductive tape 80 in the process of attaching the second polarizer 50, the transparent conductive material layer 60 is exposed to a predetermined width An exposed area EA is required. At this time, the attachment of the conductive tape 80 is manually performed by the operator, and the exposed area EA of the transparent conductive material layer 60 is required to have a width of at least about 2 mm. When the exposed region EA of the transparent conductive material layer 60 is less than 2 mm, it is difficult to attach the conductive tape 80 and the area attached on the transparent conductive material layer 60 is too small, A phenomenon of falling occurs over time.

Therefore, the exposed area EA of the transparent conductive material layer 60 has a width of about 2 mm or more. Further, in the conventional transverse electric field type liquid crystal display device having such a configuration, the width of the bezel To the end of the substrate) has a size of about 3 to 4 mm in consideration of the attachment error of the first and second polarizing plates 40 and 50, and the like.

However, in recent display devices, it is a trend to minimize the width of the bezel to 2 mm or less, and a transverse electric field type liquid crystal display device that conforms to the trend of such a display device is required.

It is an object of the present invention to provide a transverse electric field type liquid crystal display device capable of effectively discharging unnecessary external electric charges such as static electricity.

It is another object of the present invention to provide a transverse electric field type liquid crystal display device capable of realizing a narrow bezel that is a trend of a current display device while having a structure for discharging static electricity effectively, and a bezel width of 2 mm or less.
