Abstract

PURPOSE:To prevent a shift in color when a display picture is seen while held at the horizontal angle by providing a beltlike color filter between a liquid crystal layer and a front-side polarizing plate at right angles to the erect direction of the display picture. CONSTITUTION:Transparent electrodes 6 and 8 supported by supporters 5 and 9 are provided on the front and rear surfaces of the liquid-crystal layer 7; and a polarizing plate 10 is provided on the rear surface of the supporter 9 and color filters 1-3 are provided on the front surface side of the supporter 5 in a beltlike shape at right angles to the erect direction of the display picture. Then, a polarizing plate 4 is provided thereupon. Consequently, even when the display picture is seen at some angle to the element, light which is passing through some color filter never passes through another color filter, so that no color shift is caused.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a color liquid crystal display element, and particularly to improvement of color shift thereof.

Color filters 1 to 1 in conventional color liquid crystal display elements
3, as shown in FIGS. 1 and 2, three colors, R2G and H, were arranged as a set in the vertical direction of the display screen. FIG. 3 shows a conventional color liquid crystal display element, in which transparent electrodes 6 and 8 supported by supports 5 and 9 are provided on the front and back sides of the liquid crystal layer 7, respectively, and on the front side of the support 5. A polarizing plate 4 is provided through color filters 1 to 3, and a polarizing plate 10 is further provided on the back side of the support 9.

In the above-described conventional color liquid crystal display element, applying a voltage to each transparent electrode 6.8 changes the vertical angle of the liquid crystal molecules in the liquid crystal layer 7, and rotates the plane of polarization in this part. By eliminating them, a bright area is created, and a 19-color color display is performed on the combination of this bright area and the color filters 1 to 3 arranged in the vertical direction of the image.

However, in the above-mentioned color liquid crystal display element, when the element is viewed from a position horizontally shifted from the element, the light that should pass through the color filter on the far side passes through the color filter on the side closer to the viewer. As a result, the amount of light that passes through the color filter on the far side decreases, resulting in color shift.

The present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and provides color display at wide angles in the horizontal direction without causing color shift when viewed from the side in the horizontal direction with respect to the device. It is an object of the present invention to provide a liquid crystal display element that allows accurate viewing of images.

Embodiments of the present invention will be described below with reference to the drawings.

In this embodiment, as shown in FIGS. 4 and 5, a color filter 1 is provided between a support 5 and a polarizing plate 4.
3 are provided in a band shape in a direction perpendicular to t to the upright direction of the display image of the element, that is, in the lateral direction. This is the same as the other 14th or conventional one.

In the above embodiment, since the color filters 1 to 3 are arranged horizontally in a band shape, even when the displayed image is viewed at an angle with respect to the element in the horizontal direction, the color filters 1 to 3 are arranged horizontally in the form of a band. The desired light will not pass through other color filters, and no color shift will occur. However, the transmitted light, H-, decreases somewhat. Incidentally, FIG. 6 shows an example in which a large number of sets of color filters 1 to 3 are arranged upwardly.

As described above, in the present invention, since the Cassie filter element is arranged in a band shape in the horizontal direction with respect to the displayed image, color shift does not occur even when the displayed image is viewed with an angle 1K in the horizontal direction. .
