Patent ID: 7791677

Claim:
A display apparatus comprising: a substrate; an electroconductive layer provided on the substrate; an insulating layer covering the electroconductive layer; a semiconductor device including a drain electrode, a semiconductor, a gate electrode, and a source electrode, the semiconductor device also comprising a thin film transistor device in which the gate electrode, the semiconductor, and the source/drain electrodes are stacked in the stated order from a substrate side; a display device including an electrode which is connected with the drain electrode of the semiconductor device; and a capacitor electrode provided over the electroconductive layer which is covered with the insulating layer, wherein, in an in-plane direction of the substrate, at least a part of the electroconductive layer is closer to a semiconductor device side than the capacitor electrode, and wherein the electrode of the display device and the drain electrode of the semiconductor device which is connected with the electrode of the display device form a first capacitor with the capacitor electrode and a second capacitor with the electroconductive layer.
