Abstract:
1. An electro-optical device comprising: an X address decoder that selects one of a plurality of X selection lines; a Y address decoder that selects one of a plurality of Y selection lines; and a plurality of pixel blocks, each of the pixel blocks being arranged corresponding to intersections of the plurality of the X selection lines and the plurality of the Y selection lines; wherein each of the plurality of the pixel blocks includes a plurality of pixel circuits, the pixel circuits of a same column share both a common bit line and a common complementary bit line, different from the common bit line, each of the pixel circuits includes a memory circuit, a selection circuit, and a pixel electrode, the memory circuit includes a plurality of transistors that become conductive between the bit line, the complementary bit line, and terminals of the memory circuit at a time of concurrent selection of a respective X selection line and Y selection line corresponding to the pixel block including the plurality of the transistors, the memory circuit storing a data bit which is fed to the corresponding bit line when the plurality of the transistors are conductive, and the selection circuit selects a signal that turns an electro-optical element into an ON state or an OFF state according to the data bit stored in the memory circuit, so as to feed the selected signal to the pixel electrode, wherein the memory circuit is a complementary memory, and the plurality of transistors that become conductive between the bit line, the complementary bit line, and terminals of the memory circuit at a time of concurrent selection of a respective X selection line and Y selection line corresponding to the pixel block including the plurality of the transistors are all conductive at a same time to input to the memory circuit, at the same time, the data bit on the common bit line and a complementary data bit on the common complementary bit line.
