Abstract:
1. An electro-optical device, comprising: a plurality of scanning lines and a plurality of data lines intersecting each other in an image display area; a plurality of pixels connected to the plurality of scanning lines and the plurality of data lines; n-number of image-signal lines to which image signals are supplied, n being a number greater than or equal to 2, the image-signal lines being located in a peripheral area that is peripheral to the image display area; a sampling circuit in the peripheral area, the sampling circuit including thin-film transistors corresponding to the respective data lines, the thin-film transistors including a first group of n thin-film transistors connected to n data lines and a second group of n thin-film transistors connected to a different n data lines, the first group and the second group being located adjacent to each other and separated by a space therebetween, the thin-film transistors each including: a data-line driving circuit to supply sampling-circuit driving signals to the gates of the thin-film transistors in the sampling circuit, data-line driving circuit simultaneously driving n data lines at a time by first supplying sampling-circuit driving signals to the gates in the first group and subsequently to the gates of the thin-film transistors in the second group; and an electromagnetic shield disposed entirely between thin-film transistors of the first group and thin-film transistors of the second group in the sampling circuit, no electromagnetic shield disposed in between any other parts of the thin-film transistors in either the first group or the second group.
