Active matrix substrate having channel protection film covering transistor channel, and display apparatus and/or, television receiver including same
An active matrix substrate of the present invention is arranged so that each pixel area has a transistor and a capacity electrode which is able to function as an electrode of a capacity. The active matrix substrate includes a conductor which is provided in a layer below the capacity electrode and is able to function as the other electrode of the capacity. The gate electrode of each transistor and a gate insulating film covering the conductor have a thin section with reduced thickness, in an on-conductor area overlapping the conductor. At least a part of the thin section overlaps the capacity electrode. In this way, the active matrix substrate which can reduce inconsistency in capacitance values of capacities (e.g. a storage capacitor, a capacity for controlling an electric potential of a pixel electrode, and a capacity which can function as both of them) provided in the substrate.
