Abstract
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.
Claims3
A display device comprising:
- a plurality of pixel circuits arranged in a matrix form;
- a first scanner adapted to output a drive signal onto a drive wiring;
- and
- a second scanner adapted to output a data signal onto a data wiring, each of the plurality of pixel circuits including
- a switching transistor whose conduction is controlled by the drive signal supplied to the control terminal,
- the drive wiring adapted to propagate the drive signal,
- the data wiring adapted to propagate the data signal, and
- an electro-optical element whose brightness changes with change in current flowing, wherein
- the drive wiring is formed on a first wiring layer and connected to the control terminal of the switching transistor and the first scanner,
- the data wiring layer is formed on a second wiring layer and connected to a first terminal of the switching transistor and the second scanner, and
- 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.
