The invention provides an electro-optical device that can include a plurality of scanning lines, a plurality of signal lines, a plurality of pixels arranged corresponding to intersections of the scanning lines and the signal lines, and heat-release sections. The pixels can each include corresponding transistors and corresponding light-emitting elements, the light-emitting elements emit light in the direction that light is withdrawn, and the heat-release sections include heat release portions, located on the side opposite to the light-withdrawing direction of the light-emitting elements, having electrical conductivity. Accordingly, the invention can enhance the environmental resistance of an electro-optical device including light-emitting elements.
