Abstract:
1. A liquid crystal display device comprising: a first glass substrate having a thin film transistor and a pixel electrode; a second glass substrate having a color filter; and a liquid crystal layer disposed between the first and second substrates; wherein the thin film transistor includes a silicon film, a gate electrode, and a source electrode which is electrically connected to the pixel electrode; wherein the pixel electrode includes a reflective electrode forming a reflective region and a light-transmissive electrode forming a transmissive region, and a thickness of the liquid crystal layer of the transmissive region is greater than a thickness of the liquid crystal layer of the reflective region; wherein between the silicon film and the first substrate and between the pixel electrode and the first substrate, a silicon oxide film and a silicon nitride film are formed, the silicon nitride film being formed between the silicon oxide film and the first substrate; wherein a film thickness of the silicon nitride film is larger than a film thickness of the silicon oxide film; wherein the silicon nitride film and the silicon oxide film are configured so as to reduce reflection light from the transmissive region of the liquid crystal display device; wherein a gate insulation film is formed between the silicon film and the gate electrode; wherein an interlayer film is arranged close to the gate insulation film and is interposed between the gate insulation film and the pixel electrode; and wherein the film thickness of the silicon nitride film falls within a range of 126 nm to 165 nm.
