Abstract
A method of manufacturing an electro-optical device includes the steps of: forming a recessed portion at an insulating member; forming a first capacitance electrode, a capacitance insulation film, and a second capacitance electrode along the recessed portion; concurrently patterning the first capacitance electrode, the capacitance insulation film, and the second capacitance electrode; removing a portion of the second capacitance electrode; forming an interlayer insulating film; and etching, until a portion of the first capacitance electrode is exposed in plan view, a region where the portion of the second capacitance electrode is removed, to form a contact hole penetrating through the interlayer insulating film and the capacitance insulation film.
