Patent attributes
An electro optical device having a substrate, scanning lines, data lines, and pixel electrodes arranged to correspond to intersections of scanning and data lines, a counter electrode opposite the substrate from a pixel electrode, an emission layer between the pixel electrode and the counter electrode, a driving transistor connected to the pixel electrode, a driving circuit for supplying a signal to at least one of the scanning lines and data lines, a potential supply line for the driving circuit, an insulating film between the driving transistor and the counter electrode, the insulating film in a first area on the substrate, and a planarizing layer covering the counter electrode, wherein the potential supply line extends along an edge of the substrate in a second area, and the planarizing layer covers the insulating film and overlaps with at least a part of the potential supply line in the second area.
