Abstract
Exemplary embodiments of the present invention provide an electro-optical device having a sampling circuit including a plurality of thin-film transistors corresponding to respective data lines, the thin-film transistors each including i) a drain connected to a drain line extending from the data line, ii) a source connected to a source line extending from an image-signal line in the extending direction of the data line, and iii) a gate interposed between the drain line and the source line; a data-line driving circuit supplying sampling-circuit driving signals to the gate; and an electromagnetic shield disposed in a space between two adjacent thin-film transistors. This reduces the occurrence of image problems due to parasitic capacitance between the thin-film transistors in the sampling circuit.
