Abstract:
1. An in-plane switching liquid crystal display device comprising: a liquid crystal; and first and second substrates arranged with the liquid crystal therebetween, wherein the first substrate has formed thereon a reflection film which is conductive, an insulation film formed above the reflection film, a light-transmitting pixel electrode formed above the insulation film and a light transmitting counter electrode formed above the insulation film in each pixel region, the liquid crystal is driven by an electric field formed between the pixel electrode and the counter electrode of the first substrate, the reflection film has a first region which is overlapped with the pixel electrode, a second region which is overlapped with the counter electrode, and a third region which is overlapped with none of the pixel electrode and the counter electrode when viewed in a plan view, and the reflection film is supplied with a voltage through a switching element which is arranged at said each pixel region.
