Electro-Optical Device and Electronic Apparatus

Abstract

To improve the unevenness of brightness. A plurality of pixel circuits is arranged in a pixel region A. Main power lines LR, LG, and LB are provided in the outside of the pixel region A. In addition, first sub-power lines Lr 1 , Lg 1 , and Lb 1 and second sub-power lines Lr 2 , Lg 2 , and Lb 2 are provided in the inside of the pixel region A so as to be connected to each other at sub-power line connecting points P. Further, the pixel circuits are connected to the first sub-power lines Lr 1 , Lg 1 , and Lb 1 at pixel connecting points Q. The structure in which these power lines are arranged in a mesh shape enables a considerable reduction in voltage drop and the improvement of brightness unevenness.
