Patent ID: 8207925

Claim:
An electro-optical device comprising: a substrate; a scanning line provided over the substrate, the scanning line sequentially supplying scanning signals; three data lines for supplying image signals, the three data lines intersecting the scanning line; three sub pixel units aligned in a direction in correspondence with intersections of the three data lines and the scanning line, the three sub pixel units corresponding to R (red color), G (green color), and B (blue color), respectively; and a sampling unit for supplying the image signals to the three data lines, the sampling unit including three sampling circuits aligned in a different direction than the direction in which the three sub pixel units are aligned, the three sampling circuits corresponding to R, G, and B, respectively, and including a first sampling circuit and a second sampling circuit, the first sampling circuit including: a first thin film transistor having a first gate electrode, a first source, and a first drain aligned in a first direction, the first gate electrode extending in a second direction that intersects the first direction; and a first image signal line; the second sampling circuit including: a second thin film transistor including a second gate electrode, a second source and a second drain; and a second image signal line for supplying the image signals before or after sampling, the second image signal line being electrically connected to the second source or the second drain of the second thin film transistor, the second image signal line extending in the second direction across the first gate electrode and overlapping the first gate electrode in the plan view.
