In general, a polarizing plate is made of a polymeric material such as polyvinyl alcohol or cellophane, which adsorbs iodine or dye, and stretches and aligns it in a certain direction to form a polarizing element, with fibers such as cellulose acetate on both or one side of the polarizing element. It is configured to adhere and hold a transparent substrate such as base resin, acrylic resin film, or glass to stably protect polarization.

By placing such polarizing plates on the top and bottom or on both sides of an electrode cell filled with liquid crystal so that their polarization axes are perpendicular to each other, a desired monochromatic pattern display such as a numerical display based on the difference in brightness and darkness can be produced depending on the presence or absence of an applied voltage. Although liquid crystal display devices that display such images are widely known, there have been complaints that the hue is a monochromatic pattern that tends to flow monotonously, lacks aesthetic appeal, and cannot display colorful and mobile patterns. Developed a polarizing plate for multicolor display and its manufacturing method, and published Utility Model Application Publication No. 15549/1983, Japanese Patent Application Publication No. 18685/1983, and Japanese Patent Application Publication No. 1983/1989.

In the above configuration, the intersecting angle of the polarization axes of the two colored polarizing films 2 and 4 is not limited to 60°, but is dependent on the polarization angle of the colored polarizing film itself and the angle at which the polarizing plate is attached to the liquid crystal plate. It can be selected as appropriate by considering the following. Furthermore, when colored polarizing films are superimposed, there is no particular problem depending on the application even if some of the colored portions overlap each other. Furthermore, the hue divisions of the colored polarizing film can be formed in desired positions and shapes using known printing or transfer methods, so that the hue zones of the colored polarizing film can be formed in desired positions and shapes.
It is not limited to striped colored polarized bands such as B, C, and D, but can be printed in multiple colors in any pattern such as letters, figures, and patterns.

By using the multicolor polarizing plate of the present invention as described above in combination with a polarizing plate attached to the front or back surface of a liquid crystal cell, a section where the polarization axes of the polarizing plate are orthogonal or intersect and a section where the polarization axis is parallel are formed. It is possible to display a positive display in orthogonal or intersecting sections and a negative display in parallel sections, respectively, on the same display board. Currently, there are no known polarizing plates for multicolor displays that can simultaneously form both positive and negative displays on the same display board, and they are suitable for displaying various measuring instruments such as automobiles, electronic computers, and watches. When used on boards, it has a remarkable effect that is expected to be applied to new uses aiming at special display effects, such as using caution displays, warning displays, etc., counting or measurement displays, positive displays and negative displays.
