Abstract

Abstract The present invention is, in a liquid crystal display apparatus, to increase a resolution by disposing every other one of picture element electrodes (P 11 to P nm ) with a displacement of 1/2 picture element pitch and also to obtain an excellent quality of picture by providing color filters (R, G, B) in association with these picture element electrodes.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 239 words
In a liquid crystal display apparatus in which a plurality of first signal lines are provided parallel to one another and extend in the vertical direction, a plurality of second signal lines are provided parallel to one another and extend in the horizontal direction, picture element electrodes of display liquid crystal cells are respectively provided with a plurality of switching transistors at intersections where said first and second plurality of signal lines intersect with one another, a plurality of gate lines to which a control signal for controlling said switching transistors is supplied, said plurality of gate lines extending parallel to one another in the horizontal direction, said liquid crystal display apparatus being characterized in that said picture element electrodes are formed at every other one in the horizontal direction with a displacement of 1/2 picture element pitch distance in said vertical direction, wherein during one interlaced field, arbitrary picture element electrodes are aligned at every other one in the horizontal direction and picture element electrodes are located upwardly from the former with a displacement of 1/2 picture element pitch distance which constitute a horizontal line, while during the other interlaced field, said arbitrary picture element electrodes and picture element electrodes are located downwardly from the former with a displacement of 1/2 picture element pitch distance which constitutes a horizontal line to thereby carry out the display, and said gate lines are straight and extend in the horizontal direction.
