Liquid crystal display device
View Patent ↗An array substrate of a liquid crystal display device includes an insulating substrate, a gate line extending in a first direction on the insulating substrate, a first insulation film which is disposed to cover the gate line, pixel electrodes which are disposed on the first insulation film in respective pixels, a source line which is disposed on the first insulation film and extends between the pixel electrodes along a second direction, a second insulation film which is disposed to cover the pixel electrode and the source line, and a common electrode which is disposed on the second insulation film in a manner to face the pixel electrode of each of the pixels and to face the gate line, and includes a slit which is opposed to the pixel electrode.
1. A liquid crystal display device which is configured to hold a liquid crystal layer between a first substrate and a second substrate, the first substrate comprising:
an insulating substrate;
a gate line extending in a first direction on the insulating substrate;
a first insulation film which is disposed to cover the gate line;
pixel electrodes which are disposed on the first insulation film in respective pixels;
a source line which is disposed on the first insulation film and extends between the pixel electrodes along a second direction which crosses the first direction;
a second insulation film which is disposed to cover the pixel electrodes and the source line; and
a common electrode which is disposed on the second insulation film in a manner to face the pixel electrodes and to face the gate line, and includes a slit which is formed to face the pixel electrodes, the common electrode being disposed in a trench formed between one of the pixel electrodes and the source line in the second insulation film and to surround the one of the pixel electrodes.
2. The liquid crystal display device according to claim 1 , wherein the common electrode is disposed to face the source line, and formed over an entire display area which the pixels are disposed in a matrix.
3. The liquid crystal display device according to claim 1 , wherein the second substrate includes a lattice-shaped light-shield layer which faces the gate line and the source line.
4. The liquid crystal display device according to claim 1 , further comprising a switching element which is disposed on the insulating substrate and includes a drain electrode which is connected to the pixel electrode.
5. The liquid crystal display device according to claim 1 , wherein the pixel electrode and the common electrode are formed of a light-transmissive, electrically conductive material.
