Abstract:
1. An electro-optical device comprising: a display unit that has a plurality of switching elements provided at intersections of a plurality of scanning lines and a plurality of data lines and that drives the plurality of switching elements based on image signals supplied to the plurality of data lines so as to display images; a driving unit that controls driving of the display unit through a phase expansion so as to drive the plurality of switching elements for predetermined blocks; m×n signal wiring lines that transmit image signals, the image signals being divided into m (where m is a natural number of 2 or more) parallel data sequences and each of the data sequences including n (where n is a numerical value of 2 or higher and also a natural number of less than or equal to m) parallel image signals, and that have extended portions such that the m×n signal wiring lines are grouped into a plurality of groups of signal wiring lines, each of the plurality of groups of signal wiring lines including n signal wiring lines for each data sequence on a substrate, and such that the plurality of groups of signal wiring lines for each data sequence are grouped; a plurality of supply voltage lines being applied a supply voltage, wherein at least one of the supply voltage lines is formed between two adjacent groups of the plurality of groups of signal wiring lines, runs along one of the signal wiring lines of the two adjacent groups in the extended portions, and is not formed between two adjacent signal wiring lines of a same group of the plurality of groups of signal wiring lines; at least one sampling signal line supplied with a sampling signal from the driving unit, wherein at least a portion of each sampling signal line is adjacent and between two shield lines from a plurality of shield lines, the plurality of shield lines being applied the supply voltage, the plurality of shield lines being branched in a direction of the plurality of data lines, from one of the supply voltage lines; and a plurality of mounting terminals, the signal wiring lines being disposed between the plurality of mounting terminals and the driving unit, the plurality of groups of signal wiring lines each being comprised of more than one group of signal wiring lines.
