Claim Text:
1. A display device comprising: a first substrate; a pixel array including a plurality of pixels arranged in a matrix on the first substrate, respective ones of the pixels comprising a write transistor, a drive transistor configured to control a current based on a potential applied to a gate electrode of the drive transistor, and a first capacitor including a second electrode formed in a second metal layer; and a second substrate arranged on the pixel array, wherein the pixel array further comprises a second capacitor including a first electrode formed in a first metal layer and a third electrode formed in a third metal layer, the first metal layer is disposed on the second metal layer with a first insulation layer sandwiched between the first metal layer and the second metal layer, the third electrode is disposed to face the first electrode with at least a second insulation layer sandwiched between the first electrode and the third electrode, a third insulation layer with an opening region is disposed between the second insulation layer and the third metal layer, and a majority of the opening region is overlapping with the first electrode, a first surface of the first electrode faces the first substrate and a second surface of the first electrode faces the second substrate, and the pixel array further comprises an electro-optical element which includes an electro-optical material layer, and the second substrate is bonded to the first substrate by an adhesive material so that the electro-optical material is sealed between the first substrate and the second substrate.
