Liquid crystal display
InactiveUS20050128381A1Maintain whitenessReduce level differenceOptical filtersNon-linear opticsTransmittanceResist
In order to suppress color tint during display of black, chromaticity is changed when black is displayed while maintaining chromaticity when white is displayed. For this purpose, the pigment to be dispersed in a color resist is adjusted in particle size and concentration. Such adjustment is so performed that the chromaticity difference between displayed white and black becomes 0.01 or smaller in the x-y chromaticity coordinates by varying the transmissivity of color pixels during display of black. With such a structure, successfully provided is a color liquid crystal display capable of preventing color tint in displayed black, while keeping white chromaticity at the desired level.
