Abstract:
An electro-optical device substrate, comprising:a plurality of wires; a plurality of switching devices interposed between each parallel pair of the wires, wherein the each pair of the wires comprise adjacent two wires, and each of the switching devices belongs to one of a first group and a second group, and one of the adjacent switching devices interposed between a first wire and adjacent one wire and another one of the adjacent switching devices interposed between the first wire and adjacent another wire belongs to different groups, and the switching devices belonging to the groups are switched on/off in units of each group; and a shift register that serially shifts data supplied to the each pair of the wires, the electro-optical device substrate allowing a current to pass through the each pair of the wires connected in series via the switching devices switched on or applying a voltage to the first wire of the each pair of the wires, and allowing a current to pass through the each pair of the wires connected in series via the switching devices switched on or applying a voltage to the first wire of the each pair of the wires based on the data which is shifted for serially by the shift register one after another.
