Color liquid crystal display element
专利汇可以提供Color liquid crystal display element专利检索，专利查询，专利分析的服务。并且PURPOSE: To make an excellent multicolor display including a white display by specifying the color of transmitted light subjected to photometry while a couple of polarizing plates in use are arranged on one side of two liquid crystal layers while having their axes of polarization in parallel after liquid crystal is injected.
CONSTITUTION: The color of the transmitted light subjected to photometry while the couple of polarizing plates in use are arranged one over the other on one side of the two liquid crystal layers while having their axes of polarization in parallel after the liquid crystal is injected is so specified that 0.30≤x≤0.35 and 0.25≤y≤0.30, where (x) and (y) are values in a CIE chromaticity diagram. Then dielectric and anisotropic nematic liquid crystal containing an optically active substance is sandwiched between a couple of transparent substrates which are arranged almost in parallel and the twist angle of liquid crystal molecules between both electrodes is set to 180-300° when no voltage is applied. Consequently, a whitish full-color or multicolor display can be made and the sharp display of high display quality is realized.
