Abstract

An electro-optical device has electro-optical elements provided in a pixel region of a substrate, pixel electrodes, a common electrode, interconnects electrically connected with the pixel electrodes, a conductive section electrically connected with the common electrode, a common interconnect electrically connected with the interconnects, a number of the common interconnect being less than a number of the interconnects, and a side interconnect which is provided in an end region separated from a region in which the pixel region is provided by a straight line passing outside the pixel region and is electrically connected with the conductive section.

Description

technical field [0001] The present invention relates to an electro-optical device and a method of manufacturing the same. Background technique [0002] In a device having a plurality of wirings such as an electroluminescent panel, when all the wirings are formed on a single substrate, the wiring area (for example, a region called an edge at the periphery of the substrate) becomes large, resulting in an enlarged substrate. Therefore, it is desirable to reduce the wiring area (for example, the edge). Contents of the invention [0003] The object of the present invention is to reduce the wiring area (for example, the edge). [0004] (1) The electro-optic device of the present invention includes a substrate, a plurality of pixel electrodes provided in the pixel region of the substrate, a plurality of electro-optical elements respectively provided corresponding to the plurality of pixel electrodes, and a plurality of electro-optic elements corresponding to the plurality of pix...
