Abstract:
1. An electro-optical device having a display region in which a plurality of pixels are arranged in a matrix, comprising: switching elements each corresponding to one of the plurality of pixels; a first sealed wiring portion that is formed in a rectangular shape arranged outside of and surrounding the entire display region; and a second sealed wiring portion that is formed on an element substrate so as to be arranged outside of the first sealed wiring portion and to surround only three sides of the display region, the second sealed wiring portion including a common electrode wiring line surrounding a first side of the display region, a second side of the display region, and a portion of a third side of the display region, the common electrode wiring line having a width greater than a width of the first sealed wiring portion, wherein the first sealed wiring portion includes a fourth side other than the three sides at which the second sealed wiring portion is arranged, wherein a data line that is connected to a data line driving circuit includes a first electrostatic protection circuit and the data line is connected to the portion of the common electrode wiring line on the second side of the display region through a second electrostatic protection circuit, and a scanning line includes a third electrostatic protection circuit and the scanning line is connected to the portion of the common electrode wiring line on the first side of the display region through a fourth electrostatic protection circuit, and wherein the first sealed wiring portion is connected to the data line through a first connecting member, then through the common electrode wiring line, and then through the second electrostatic protection circuit and the first electrostatic protection circuit, the first sealed wiring portion is also connected to the scanning line through a second connecting member and then through the fourth electrostatic protection circuit and the third electrostatic protection circuit, and the first sealed wiring portion is not directly connected to the data line driving circuit.
