Abstract
An electrooptic device includes: a plurality of parallel signal lines provided in a pixel array region in which a plurality of pixels is arrayed; a driving circuit electrically connected to a first end of each of the signal lines outside the pixel array region; and a protection circuit in which a diode device is electrically connected to a second end of the signal line, the diode device dissipating static electricity from the signal line. The resistance of the portion of the signal line from the center of the length to the driving circuit is higher than that of the portion of the signal line from the center to the diode device.
