することで画像を構成している。The use of liquid crystal displays as display devices that can be driven with low power consumption is expanding more and more, and in recent years, expectations have increased for them as an alternative to CR displays and color TV picture tubes, and many research results have been published. Currently, most liquid crystal displays use twisted nematic liquid crystals because of their fast response speed and high contrast ratio. FIG. 7 shows an example of the display principle of a transmission type twisted nematic liquid crystal display. A transmissive liquid crystal display has the smallest unit (hereinafter referred to as a pixel) that has the function of controlling light transmission depending on the ON/OFF state.
Consisted of. A pixel consists of a transparent electrode 704 provided on two substrates 702 between two polarizing plates 703 facing each other in a direction such that the polarization axes are parallel to each other, and a twisted nematic liquid crystal 705 arranged in a twisted manner. provided and configured. In the ON state, as shown in FIG. 7(a), a potential is applied to the transparent electrophoresis 704, causing the liquid crystal 705 to stand up, allowing light from the light source 700 to pass therethrough. However, in the OF F' state, the liquid crystal 705 is between the two transparent electrodes 704 as shown in FIG.
The light source 7 follows the twisted liquid crystal molecules.
Since the polarization axis of the light from 00 is rotated by 90 degrees, it cannot pass through the other polarizing plate. A liquid crystal display constructs an image by combining a large number of pixels and controlling each point with 0NIJFF.

この液晶ディスプレイ811は視野面の見る角度によシ
画質特にコントラストが変るという視野角依存性が大き
いという欠点がある。The conventional liquid crystal display described above uses a polarizing plate 703 to control light transmission. However, a polarizing plate has a property that it cannot polarize light that is obliquely incident on the polarizing plane, and as shown in FIG.
The liquid crystal display 811 transmits light even when the pixel 806 is in the OFF state, and therefore, the liquid crystal display 811 has a drawback that the image quality, particularly the contrast, changes depending on the viewing angle of the viewing plane, which is highly dependent on the viewing angle.
したがって、視野面に対して垂直以外の角度から見た場
合、正規の制御量とは異なる透過光量となり、画質を低
下させる問題を有していた。Therefore, when viewed from an angle other than perpendicular to the viewing plane, the amount of transmitted light differs from the normal control amount, resulting in a problem of deteriorating image quality.

ができるようにしたものである。The above-mentioned conventional liquid crystal displays do not have a lining to prevent light from being transmitted in an oblique direction, which causes a reduction in image quality (contrast) when viewed from an angle other than perpendicular to the viewing plane. In contrast, the present invention has a filter on the viewing surface of the liquid crystal display, and the inner wall surface of the filter or the hole itself is made of a material that has high absorption in the visible light range. The hole has a light scattering surface 2 perpendicular to the viewing surface of the liquid crystal display, and has a light scattering surface 2 on the opposite side of the surface in contact with the viewing surface of the liquid crystal display, and the thickness thereof is 0.7 or more of the longest plane length of the hole. By providing a filter in contact with the viewing surface of the liquid crystal display, it absorbs the light transmitted in the diagonal direction and scatters the light transmitted vertically, so that the same image quality can be viewed from any direction. This is what I did.

た光を散乱することができる。In this embodiment, since the number of holes is larger than the number of pixels, several holes 319t are provided on the transparent electrode 304 corresponding to one pixel. For this purpose, even if the thickness of the filter part 318 is made thin, the absorption layer 310 absorbs the light that is transmitted obliquely, and the scattering surface scatters only the light that is transmitted almost perpendicularly, so that it is the same from any direction. You can see it like this. Further, in this embodiment, the leftover end can be used as the frame material, so there is an advantage that the strength can be increased. [Effects of the Invention] Next, the present invention will be explained in detail. As shown in Fig. 4, the filter has all the holes perpendicular to the polarizing plate 403 (upper side) on the viewing plane, and the inner wall layer is made of a material that has high absorption in the visible light range and is made of a frame 40.
It is formed by 7. By providing such a filter in contact with the viewing surface of the full liquid crystal display (on the upper polarizing plate 403), it is possible to absorb light from the light source 100 that passes through the polarizing plate 403 obliquely. Furthermore, by providing a scattering surface 409 on the surface opposite to the surface in contact with the viewing surface of the filter, light that is selectively transmitted through the holes of the filter and received at an angle perpendicular to or close to the polarizing plate on the viewing surface is can be scattered.

By scattering the light, it becomes possible to see the same from any angle, and as shown in FIG. 6, this has the effect of improving the viewing angle dependence of contrast.
