Abstract

A liquid crystal display device includes a first substrate, a second substrate, a first electrode and a second electrode formed on the first substrate, the second electrode being arranged at an upper layer with respect to the first electrode, a drain signal line and a gate signal line formed on the first substrate, and a liquid crystal layer driven by an electric field formed between the first electrode and the second electrode. The first electrode extends in parallel to the drain signal line and the second electrode extends at a slanted direction to the drain signal line.

Claims (14)

1. A liquid crystal display device comprising:

a first substrate;

a second substrate;

a first electrode and a second electrode formed on the first substrate, the second electrode being arranged at an upper layer with respect to the first electrode;

a drain signal line and a gate signal line formed on the first substrate; and

a liquid crystal layer driven by an electric field formed between the first electrode and the second electrode;

wherein the first electrode extends in parallel to the drain signal line and the second electrode extends at a slanted direction to the drain signal line.

2. The liquid crystal display device according to claim 1 , wherein the first electrode is provided in a same layer as the gate signal line.

3. The liquid crystal display device according to claim 1 , wherein the second electrode extends at two slanted directions to the drain signal line.

4. The liquid crystal display device according to claim 2 , wherein the second electrode extends at two slanted directions to the drain signal line.

5. The liquid crystal display device according to claim 1 , wherein an area of the first electrode is larger than an area of the second electrode.

6. The liquid crystal display device according to claim 2 , wherein an area of the first electrode is larger than an area of the second electrode.

7. The liquid crystal display device according to claim 3 , wherein an area of the first electrode is larger than an area of the second electrode.

8. The liquid crystal display device according to claim 4 , wherein an area of the first electrode is larger than an area of the second electrode.
