Title:
COLOR FILTER
Document Type and Number:
Japanese Patent JPS6135403
Kind Code:
A
Abstract:

PURPOSE: To improve the display quality of the full-color TV display on an active matrix liquid-crystal panel by arranging the three primary colors of red, green, and blue of an additive color process on respective picture elements repeatedly and linearly in parallel to data lines of a TV driving signal in one-to- one position relation.

CONSTITUTION: The active matrix liquid-crystal panel to which color filters are fitted uses MIM as a switching element. Picture elements 1 of the color filters and picture elements of the active matrix liquid-crystal panel are formed in the same shape at the same picture element pitch 6 and correspond to each other in one-to-one relation across a liquid-crystal layer. Further, the three primary colors of red R, green G, and blue B are arranged along data lines in parallel repeatedly and linearly. Consequently, a phenomenon such as a decrease in the chroma of an image due to the crosstalk of an image is evaded and a phenomenon of conspicuous stripes of the three primary colors is also improved because colored parts among picture elements due to a leak of back light from among picture elements is eliminated.
