Abstract: Color liquid crystal displays (LCD) are usually made by putting color filters onto the individual pixels. These color filters are resins with color pigments. Full color displays can be made by a combination of the red, green and blue primary colors. This coloring scheme is the predominant technology for active matrix as well as passive matrix LCDs currently in use. This new method makes available an alignment method for liquid crystal cells, making it possible to obtain vivid colors in a low twist LCD without the use of color filters. The vertical alignment allows for the voltage off state to be very bright. It can also be colored depending on the polarizer angles. By turning on the voltage, the display will show various colors. Such displays have many applications in situations requiring only a few colors without gray scales. Examples are watches and clocks that can change colors, electronic games, etc. The invention can be truly reflective as well as transflective in nature, and is simple to produce.
