Abstract:
1. An electro-optical device comprising: a substrate; a plurality of unit circuits formed in an operating region of the substrate corresponding to intersecting regions of a plurality of scanning lines and a plurality of data lines, each of the unit circuits including an electro-optical element; at least one peripheral circuit which includes an active element and is formed adjacent to the operating region; and a sealing member which seals the electro-optical elements and includes an attachment section to the substrate, the attachment section being located to overlap the peripheral circuit, wherein the peripheral circuit is one of a scanning line driver circuit, a test circuit and a precharge circuit, the scanning line driver circuit supplying a scanning signal to the unit circuits through the scanning lines, the test circuit testing the unit circuits to determine whether or not each of the unit circuits is defective, and the precharge circuit outputting a precharge signal to the data lines.
