Patent ID: 7391052

Claim:
An electro-optical device, comprising: a substrate; a scanning line provided on the substrate and extending in a scanning line direction; a data line extending in a data line direction crossing the scanning line direction; a pixel electrode; and a transistor connected to the scanning line, the data line, and the pixel electrode, the transistor including: a semiconductor region including a channel region having at least one end in the scanning line direction electrically connected to the data line; and a portion of the scanning line having a first and a second end at opposite ends of the portion in the scanning line direction and a third and a fourth end at opposite ends of the portion in the data line direction, both of the first and second ends being at least partially disposed within the semiconductor region, both of the third and the fourth ends having portions that extend outside of the semiconductor region on either side of a portion disposed within the semiconductor region, wherein the third end has a fifth portion disposed within the semiconductor region connecting the portions of the third end that extends outside of the semiconductor region; and the fourth end has a sixth portion disposed within the semiconductor region connecting the portions of the fourth end that extends outside of the semiconductor region.
