Patent ID: 7446338

Claim:
A display panel comprising: a transistor array substrate which includes a plurality of pixels and comprises a plurality of transistors for each pixel, each of the transistors including a gate, a gate insulating film, a source, and a drain; a plurality of interconnections which are formed to project from a surface of the transistor array substrate, and which are arrayed in parallel to each other; a plurality of pixel electrodes for the plurality of pixels, respectively, the pixel electrodes being arrayed along the interconnections between the interconnections on the surface of the transistor array substrate; a plurality of light-emitting layers formed on the pixel electrodes, respectively; and a counter electrode which is stacked on the light-emitting layers, wherein said plurality of transistors for each pixel include a driving transistor, one of the source and the drain of which is connected to the pixel electrode, a switch transistor which makes a write current flow between the drain and the source of the driving transistor, and a holding transistor which holds a voltage between the gate and source of the driving transistor in a light emission period.
