Abstract:
1. A substrate for an electro-optical device comprising: a plurality of scanning lines; a plurality of signal lines that are provided so as to cross the plurality of corresponding scanning lines; a plurality of pixel electrodes that are disposed in a matrix so as to correspond to intersections of the plurality of scanning lines and the plurality of signal lines; a plurality of amplifiers each of which has a first node and a second node, the first node being electrically connected to a corresponding signal line and being input with a first potential signal supplied to a corresponding pixel electrode, the second node being input with a second potential signal serving as a reference potential, each amplifier comparing a potential of the first potential signal with a potential of the second potential signal, and outputting signals corresponding to the potential of the first node being decreased when the first potential signal is low, and corresponding to the potential of the first node being increased when the first potential signal is high, each amplifier being provided such that at least two signal lines of the plurality of signal lines correspond to one of the first and second nodes; a selection unit that selects one signal line of the at least two signal lines; and a connection unit that electrically connects the selected signal line to the one of the first and second nodes of the amplifier.
