Patent ID: 8304769

Claim:
An active matrix substrate comprising: a transistor; a pixel electrode electrically connected to the transistor; a conductor provided in a layer below the pixel electrode and an insulating film interposed between at least the pixel electrode and the conductor, the pixel electrode overlapping the conductor; wherein the insulating film comprises a thin section and a non-thin section which is thicker than the thin section; wherein the pixel electrode includes (a) a part overlapping the thin section and the conductor, and (b) a part overlapping the non-thin section and the conductor, and wherein no other electrode is located between the pixel electrode and the conductor in the area where the pixel electrode overlaps the thin section; wherein (i) the thin section includes a part of a gate insulating film and a part of a channel protection film that contact with each other, and (ii) the non-thin section includes another part of said gate insulating film and another part of said channel protection film that contact with each other, and (iii) said gate insulating film covers a gate electrode of the transistor, and (iv) said channel protection film covers a channel of the transistor, and wherein said gate insulating film that is present in both the non-thin section and the thin section is also provided in the transistor between at least the gate electrode and a drain electrode of the transistor; and wherein the thin section is formed so that the non-thin section surrounds the thin section.
