Liquid crystal display device

摘要

A liquid crystal display device includes a thin film transistor substrate, a counter substrate, a liquid crystal layer sandwiched between the thin film transistor substrate and the counter substrate. The thin film transistor substrate includes a first electrode and a second electrode for applying an electric field in a substrate in-plane direction, the first electrode includes a plurality of strip portions which extend in a predetermined direction. A chiral dopant which imparts rotation in a direction opposite to a rotational direction of liquid crystal induced by an electric field applied between the strip portions and the second electrode is added to the liquid crystal layer, and the first electrode further includes bent portions which are bent from the strip portions.

1. A liquid crystal display device comprising:
a thin film transistor substrate; a counter substrate which is arranged to face the thin film transistor substrate in an opposed manner; and a liquid crystal layer sandwiched between the thin film transistor substrate and the counter substrate; wherein the thin film transistor substrate includes a first electrode and a second electrode for applying an electric field in a substrate in-plane direction; wherein the first electrode includes a plurality of strip portions which extend in a predetermined direction; wherein a chiral dopant which imparts rotation in a direction opposite to a rotational direction of liquid crystal induced by an electric field applied between the strip portions and the second electrode is added to the liquid crystal layer; wherein the first electrode further includes bent portions which are bent from the strip portions; wherein a direction of initial alignment direction of liquid crystal molecules in the liquid crystal layer is inclined by an angle θ (0°<θ<90°) with reference to a first edge which extends in the predetermined direction, the first edge being included in each of the strip portions; wherein each of the bent portions has a second edge inclined by an angle φ (0°<φ<90°) with reference to the first edge of each of the strip portions; and wherein the angle φ that the second edges are inclined with reference to the first edges is set larger than the angle θ that the initial alignment direction is inclined with reference to the first edges.
