Liquid crystal display device

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.

2. The liquid crystal display device according to claim 1 ,

wherein the first electrode further includes a trunk portion to which the plurality of strip portions are connected respectively; and

wherein the bent portions are arranged between the strip portions and the trunk portion.

3. The liquid crystal display device according to claim 1 ,

wherein the first electrode further includes a trunk portion to which the plurality of strip portions are connected respectively; and

wherein the bent portions are arranged on edge portions of the strip portions on a side opposite to a side where the strip portions are connected to the trunk portion.

4. The liquid crystal display device according to claim 1 ,

wherein a region to which an electric field is applied by the strip portions and the second electrode is set larger than a region to which an electric field is applied by the bent portions and the second electrode.

5. 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
