Patent ID: 7973900

Claim:
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.
