Abstract:
1. An electro-optical device comprising: a plurality of scanning lines; a plurality of data lines; a plurality of voltage supply lines; a switch circuit that controls the supply of a voltage to each of the plurality of voltage supply lines; and a plurality of pixel circuits which are disposed at intersections of the plurality of scanning lines and the plurality of data lines, the plurality of pixels circuits being coupled one of the plurality of voltage supply lines, each of the plurality of pixel circuits including an electro-optical element whose luminance corresponding to a driving current that flows through the electro-optical element, an n-channel driving transistor that is disposed between one of the plurality of voltage supply lines and the electro-optical element and whose a conduction state of the n-channel driving transistor being set according to data, and a capacitor having one electrode coupled with a gate of the n-channel driving transistor and the other electrode coupled with a node that couples the driving transistor and the electro-optical element, the capacitor retaining electric charge based on a data current supplied in a writing period before the driving period via one of the plurality of data lines.
