摘要:
A liquid crystal apparatus includes a TFT array substrate which includes gate wirings having a gate electrode, source wirings having a source electrode, a thin film transistor having the gate electrode, a semiconductor layer, the source electrode, and a drain electrode, an interlayer insulating film provided above the thin film transistor and the gate and source wirings, a transparent pixel electrode having a first transparent conductive film connected to the drain electrode through a contact hole, and put into contact with a surface of a insulating substrate through a pixel opening provided in a gate insulating film and the interlayer insulating film, a reflective pixel electrode made of an Al-alloy connected to the drain electrode, and a second transparent conductive film formed on the reflective electrode. The second transparent conductive film has a same pattern shape as the reflective pixel electrode and a thickness thereof is at least 5 nm.
