Claims4
A display device comprising:
- a pixel array section, the pixel array section includes a plurality of pixels arranged in a matrix,
- at least one of the pixels including (a) a light emitting element, (b) a write transistor configured to provide a video signal, (c) a drive transistor configured to drive the light emitting element based on the video signal, and (d) a capacitor connected between the drive transistor and a potential supply line,
- wherein the capacitor includes a first electrode, a second electrode and a third electrode which are overlapping each other in a capacitor region,
- wherein the first electrode is electrically connected to the potential supply line via a first contact hole in a first insulating layer,
- wherein the third electrode is electrically connected to the first electrode via a second contact hole in a second insulating layer below the first insulating layer, and the third electrode is opposite the power supply line with the first and second electrodes sandwiched between the power supply line and the third electrode,
- wherein the second electrode is sandwiched between the first electrode and the third electrode, and the first electrode is sandwiched between the second electrode and the potential supply line,
- wherein the potential supply line is disposed on an upper layer of the first insulating layer which covers the first electrode, and
- wherein the first contact hole and the second contact hole contact opposite sides of the first electrode.
