Abstract:
1. A semiconductor device comprising: a pixel portion in which a scanning line and a data line cross each other; a first insulating layer provided between said scanning line and a semiconductor film; a second insulating layer provided between said data line and said first insulating layer and between said semiconductor film and a gate electrode; and a third insulating layer provided between said second insulating layer and a first connecting electrode and between said second insulating layer and a pixel electrode and between said second insulating layer and a second connecting electrode; wherein said gate electrode and said semiconductor film form a crossing portion with said second insulating layer interposed therebetween and said gate electrode is connected to said scanning line outside the crossing portion, and said data line is connected to said semiconductor film by said first connecting electrode, and said pixel electrode and said second connecting electrode are connected on a same plane, and said crossing portion is arranged in an overlapping area of said scanning line and said second connecting electrode, and wherein said gate electrode comprises a material that is the same as said data line.
