Embodiment Construction

[0025]FIG. 1 to FIG. 8 illustrate an example of the present invention. FIG. 1 is a plan view showing a section of one substrate of a liquid crystal display device, and FIG. 2 is a cross-sectional view showing a cross-section of the liquid crystal display device shown in FIG. 1 cut along line II-II.

[0026]This liquid crystal display device, as shown in FIG. 1 and FIG. 2, comprises a pair of transparent substrates 1 and 2 arranged opposite each other at a predetermined gap on an observed side (upper side in FIG. 2) and a side opposite that side, and a liquid crystal layer 3 interposed in the gap between the pair of substrates 1 and 2. First and second transparent electrodes 4 and 5 for generating an electric field that is substantially parallel to the surfaces of the substrates 1 and 2 when voltage is applied are formed in isolation from each other on one of the two mutually opposed inner surfaces of the pair of substrates 1 and 2, such as on the inner surface of the substrate 2 of the...

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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a liquid crystal display device that controls the orientation of liquid crystal molecules using a transversal electric field.[0003]2. Description of the Related Art[0004]Known liquid crystal display devices include an In-plane Switching (IPS) type liquid crystal display device that controls the orientation of liquid crystal molecules using an electric field parallel to the substrates that constitute the liquid crystal display device.[0005]This liquid crystal display device comprises a pair of substrates arranged opposite each other at a predetermined gap, having been subjected to an aligning treatment in mutually parallel but opposite directions on each of the mutually opposed inner surfaces and, in the gap therebetween, a liquid crystal layer interposed substantially in parallel with the substrate surfaces, with the long axes of the liquid crystal molecules aligned in the direction of t...
