Abstract
An electro-optical device includes a plurality of pixels, a sampling circuit, electrostatic protection circuits, constant potential lines, and image signal lines. The electrostatic protection circuits switching elements having first terminals and second terminals. The first terminals are electrically connected to the second terminals when an over voltage is applied to the first terminals. The constant potential lines are connected to the second terminals of the switching elements via contact holes of the first insulating layer. The image signal lines transmit image signals supplied to input terminals to the sampling circuit. The image signal lines include first wiring line portions connected to the first terminals of the switching elements via the contact holes of the first insulating layer, and a second wiring line portion connected to the first wiring line portion via contact holes of the second insulating layer.
