A pixel circuit includes: a switching transistor whose conduction is controlled by a drive signal supplied to the control terminal; a drive wiring adapted to propagate the drive signal; and a data wiring adapted to propagate a data signal. The drive wiring is formed on a first wiring layer and connected to the control terminal of the switching transistor. The data wiring is formed on a second wiring layer and connected to a first terminal of the switching transistor. A multi-layered wiring structure is used so that the second wiring layer is formed on a layer different from that on which the first wiring layer is formed.
