Abstract:
1. A thin film transistor substrate comprising: a gate electrode and an auxiliary capacitance electrode, which are formed on a substrate; a first insulating film formed to cover said gate electrode and said auxiliary capacitance electrode; a lower source electrode, a lower drain electrode, and a pixel electrode connected to said lower drain electrode, the lower source electrode, the lower drain electrode, and the pixel electrode being formed on said first insulating film; a semiconductor film formed on said lower source electrode and said lower drain electrode and electrically connected to said lower source electrode and said lower drain electrode; a second insulating film formed on said lower source electrode, said lower drain electrode, and said semiconductor film; an upper source electrode formed on said second insulating film and electrically connected to said semiconductor film and said lower source electrode through a contact hole; an upper drain electrode formed on said second insulating film and electrically connected to said semiconductor film and said lower drain electrode through a contact hole; and a common electrode formed on said second insulating film and electrically connected to said auxiliary capacitance electrode through a contact hole.
