Abstract:
1. An electro-optical device, comprising: a plurality of scanning lines and a plurality of data lines; a combination of a first thin film transistor and a pixel electrode provided corresponding to each crossing between the scanning lines and the data lines; a conductive interlayer composed of a first conductive layer, electrically connected between the first thin film transistor and a pixel electrode; a sampling circuit having a plurality of a second thin film transistor, the second thin film transistor including a gate electrode composed of a second conductive layer as a first lead, a source region electrically connected to a second lead composed of a third conductive layer and a drain region electrically connected to the data line; a sampling signal line composed of the third conductive layer, electrically connected to the first lead of the second thin film transistor through a first contact hole; an image signal line composed of the third conductive layer; and a first relay lead composed of the first conductive layer, electrically connected to the second lead through a second contact hole, and crossing the sampling signal line so that the second lead electrically connected to the image signal line.
