。First, the light beam irradiated from the left side of Fig. 5 passes through the lower polarizing plate 1, and at this time, the light polarized in a specific direction passes through the gully and the lower glass 2, and then passes through the lower plate 3 (common electrode) and 4 (liquid crystal). The light flux is controlled through a part of the shutter composed of 6 (data electrodes). The light then passes through 7 (upper plate glass), passes through 8 (color filter) for a specific color (filter wavelength), and passes through 9 (upper polarizing plate) to reach the viewer's eyes, which are shown in alphabets.

面を見る事になる。Here, when passing through each layer 1 to 9, the luminous flux is particularly
．． In a part of the shutter constituted by 6, it is not possible to pass through the part of the shutter, that is, the part 3 and 6 facing each other. Therefore, from the perspective of the viewer, in any case when viewed from each angle of the alphabet, the invalid parts (in the figure,・You will see the display screen including 4).

点を有した。In this case, the aperture ratio is determined by the ratio to the effective area, but in the electrode wiring part such as the multi-matrix structure commonly used at present, that is, the structure with a large ineffective area, the aperture ratio is very low. The problem was that the brightness and sharpness of the image decreased.

生じ、色ムラ、色調異常、輝度ムラ等の欠点があった。Also, since the areas of 6 and 8 are equal, there may be a gap in the manufacturing process, and 7.
Due to the thickness of the plate, there was a misalignment between a portion of the shutter and the color filter layer, resulting in defects such as color unevenness, color tone abnormalities, and brightness unevenness.

明する口の方向、ハの方向についても同様である。First, a description will be given of the case where the light passing from the left side of FIG. 3 is viewed from the direction A on the right side. Here, it is assumed that the distance between the liquid crystal display device and the viewer's eye is sufficient for visual recognition of the image. Therefore, it is assumed that the optical paths are approximately parallel from A to A.5 when looking at the convex microlens surface. This also applies to the direction of the mouth and the direction of C, which will be explained below.

３．イ・４の光路も、同様に第３図の如く決定される。First, when the optical path is incident on the convex microlens, it is bent upward due to refraction at the boundary surface. And 9,
8a, but since the upper layer is actually thin, refraction here will be ignored for the sake of simplicity. It is further bent upward at the interface of the upper glass plate and reaches 6. The above is the optical path, but it goes without saying that if the light were to enter the eye, it would be in the opposite direction. Similarly for A and 2, 1 from the eye.
It reaches 6 through 0.9, 8a, and 7. At this time, 10.7
At this point, refraction occurs upward and the optical path is bent. stomach·

Further, 1 to 9 in FIG. 4 are the same as those in FIG. 1, and 11 represents a prism made of a polygonal pyramid. Here, the optical paths when the transmitted light from the fourth fixed body is viewed from each direction of the alphabet are shown as A to A, 52 mouths, 1 to 5 degrees, 5 degrees C, 1 to C, and 4, respectively. As in case I, it is assumed that the distance between the liquid crystal display device and the eyes is sufficient for visual recognition of the image. Now, the attached optical path is eye-catching.

This makes it possible to reach only the shutter forming electrode part), resulting in an improvement in the apparent aperture ratio from the clear viewing direction, which has a great effect on improving image brightness and sharpness of 7 degrees, and expanding the viewing angle. It is something that can be brought about. Furthermore, by improving the color filter area, uneven color and brightness can be prevented.
