Abstract:
1. An electro-optical device, comprising: a thin film transistor disposed corresponding to an intersection of a scanning line and a data line; a capacitor line disposed in parallel with the scanning line; a conductive layer disposed in an upper layer than a gate electrode of the thin film transistor via an insulator film; a first contact hole electrically connected between the conductive layer and a drain region of a semiconductor of the thin film transistor; a pixel electrode disposed in the upper layer than the conductive layer via an insulating film; and a second contact hole electrically connected between the conductive layer and the pixel electrode, a depth of the first contact hole being shallower than a depth of the second contact hole, the first contact hole and the second contact hole being positioned between the scanning line and the capacitor line.
