ABSTRACT:
An electrooptic device includes a substrate and plurality of pixel units. Each pixel unit includes a pixel electrode; an active element; a conductive layer below the pixel electrode connecting the active element to the pixel electrode; a resin film between the active element and the pixel electrode and between the conductive layer and the pixel electrode, having a small hole overlapping part of the conductive layer; a first insulating film between the resin film and the conductive layer and between the resin film and the active element, overlapping the conductive layer and the active element and having a first hole inside the small hole having a diameter equal to or smaller than the bottom of the small hole; and a second insulating film between the resin film and the pixel electrode, having a second hole continuous to the first hole forming a contact hole together with the first hole.
