An electrode structure includes a light reflection film, an insulating film formed on the light reflection film, and a transparent conductive film formed on the insulating film. The transparent conductive film is divided into pieces in a two-dimensional matrix at a predetermined pitch to form transparent pixel electrodes. Each of the transparent pixel electrodes is connected to a corresponding one of drive electrodes formed in a lower layer underlying the light reflection film, through a corresponding one of vias penetrating the insulating film and the light reflection film and insulated from the light reflection film.
