摘要： 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.

摘要： A pixel circuit of a display device of the present invention has a drive transistor which serves also as a transistor adapted to control the emission and non-emission periods of an organic EL element or other elements. A final stage buffer in an output circuit of a write scan circuit (WS) has its power supply separated from the power supply of circuit portions of a previous stage. In a first embodiment, a scan signal WS from the write scan circuit is activated instantaneously. In a second embodiment, the trailing edge of the scan signal WS falls slowly. This allows for writing of an input signal voltage in a stable manner.
