Patent ID: 8847214

Claim:
A display device comprising: a pixel array part configured to include pixels that are arranged in a matrix, respective ones of the pixels comprising an electro-optical element, a write transistor, a drive transistor, and a capacitive part, the drive transistor being configured to control a current for driving the electro-optical element based on the potential applied to a gate electrode of the drive transistor, wherein the capacitive part comprises a first electrode portion, a second electrode portion, and a third electrode portion; the second electrode portion is disposed to face one surface of the first electrode portion so as to form a first capacitance, and at least a first insulator layer is sandwiched between the first electrode portion and the second electrode portion; the third electrode layer is disposed to face the other surface of the first electrode portion so as to form a second capacitance, and at least a second insulator layer is sandwiched between the second electrode portion and the third electrode portion; and a third insulator layer with an opening region disposed between the second insulator layer and the third electrode layer, and a majority of the opening region is overlapping with at least the first electrode portion and the second electrode portion.
