Patent ID: 8269710

Claim:
An electro-optical device comprising: unit pixels arranged in a pixel region, one of the unit pixels including a red sub pixel for displaying the color red, a green sub pixel for displaying the color green, and a blue sub pixel for displaying the color blue; data lines juxtaposed side by side in a first direction in the pixel region, and including a red data line electrically connected to the red sub pixel, a green data line electrically connected to the green sub pixel, and a blue data line electrically connected to the blue sub pixel, each of the red data line, the green data line, and the blue data line extending in a second direction; image signal lines disposed in a peripheral region located at the periphery of the pixel region, the image signal lines supplying image signals; a red sampling switch electrically connected to the red data line that samples and supplies image signals to the red data line; a green sampling switch electrically connected to the green data line and that samples and supplies image signals to the green data line; and a blue sampling switch electrically connected to the blue data line and that samples and supplies image signals to the blue data line, wherein: the green sampling switch is located at a position that is closer to the pixel region than are the red sampling switch and the blue sampling switch, and the red sampling switch, the green sampling switch, and the blue sampling switch are aligned with each other in the second direction.
