IN-PLANE SWITCHING TYPE LIQUID CRYSTAL DISPLAY DEVICE
First Claim
Patent Images
1. A liquid crystal display device comprising:
- a pair of substrates arranged opposite each other at a predetermined gap, having been subjected to an aligning treatment in mutually parallel directions on each of the mutually opposed inner surfaces;
a liquid crystal layer interposed in the gap between the pair of substrates and arranged substantially in parallel with the surfaces of the substrates, with the long axis of the liquid crystal molecule in alignment with the direction of the aligning treatment;
a plurality of first electrodes provided on one of the mutually opposed inner surfaces of the pair of substrates, comprising, in each predetermined region for forming a single pixel, one linear section and another linear section that extend in directions that intersect the direction of the aligning treatment at different angles, a bent section that is provided at each end where the one linear section and the other linear section adjacent to each other, and that extends in a direction that intersects the direction of the aligning treatment at an angle greater than each of the intersecting angles of the one linear section and the other linear section and the aligning treatment direction with respect to the aligning treatment direction, and a connection section that connects these bent sections; and
a second electrode that is arranged in isolation from the first electrode on the inner surface of the one substrate, and that generates with the first electrode a transversal electric field that changes the orientation of the long axis of the liquid crystal molecule within a plane substantially parallel to the surfaces of the substrates.

Abstract
A liquid crystal display device comprises a pair of substrates subjected to an aligning treatment in mutually parallel but opposite directions, a liquid crystal layer interposed between the pair of substrates, a first electrode bent into a “<” shape, and a second electrode formed via an insulating film with the first electrode. The first electrode comprises one linear section and another linear section that extend in directions that intersect the alignment treatment direction at different angles, a bent section that is provided at each end where the one linear section and the other linear section adjacent to each other and that extends in a direction that intersects the alignment treatment direction at an angle that is greater than each of the intersecting angles of the one linear section and the other linear section and the alignment treatment direction with respect to the alignment treatment directions.
