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. A multi-layered wiring structure is used so that a second wiring layer is formed on a layer different from that on which a first wiring layer is formed.

Abstract: Disclosed herein is a display device including: a pixel array portion; a drive portion; and a power source wiring; the pixel array portion, at least a part of the drive portion configured to drive the pixel array portion and the power source wiring are forming a panel, the pixel array portion including scanning lines disposed in rows, signal lines disposed in columns, and pixels disposed in matrix in portions where the scanning lines and the signal lines cross each other, respectively, the drive portion including a scanner portion configured to drive the pixels in a line-sequential manner through the scanning lines, and a signal portion configured to supply a video signal to each of the signal lines in correspondence to the line-sequential drive, so that an image is displayed on the pixel array portion.

Abstract: Disclosed herein is a display apparatus has a pixel array section including: pixel circuits which are each provided with a driving transistor and an electro-optical device and are laid out to form a matrix; and a draw wire provided in each of the pixel circuits to serve as a wire connecting the driving transistor to a power-supply providing line, wherein the resistance of the draw wire is relatively large in the pixel circuit close to a source applying a power-supply voltage to the power-supply providing line.
