Abstract:
1. An electro-optical device comprising: a pixel region including a plurality of pixel circuits each having a light emitting element; a main power line provided in an outer circumferential portion that is external to the pixel region, the main power line including a first portion and a second portion adjacent the first portion, the first portion extending along one side of the pixel region and the second portion extending along another side of the pixel region; a plurality of first sub-power lines each connected to the first portion of the main power line and extending to the inside of the pixel region in a first direction; a plurality of second sub-power lines each connected to the second portion of the main power line and extending to the inside of the pixel region in a second direction that intersects the first direction; sub-power lines connecting points connecting the first sub-power lines to the second sub-power lines at some intersections therebetween; and pixel connecting points connecting the pixel circuits to at least one of the plurality of first sub-power lines or the plurality of second sub-power lines, the sub-power line connecting points being provided at the some intersections of the first sub-power lines and the second sub-power lines such that density of the sub-power line connecting points increases with increased distance from the main power line and increased proximity to the center of the pixel region.
