Patent ID: 8384287

Claim:
An organic EL display device in which pixels each of which is constituted of an organic El element are arranged in a matrix array, wherein power source lines which are configured to supply an electric current to the organic EL elements, video signal lines which are configured to supply video signals to the pixels, a longitudinal direction of the pixels is along the video signal line, the pixel includes a pixel circuit which is configured to control an electric current supplied to the organic El element, the pixel circuit includes a capacitance and a transistor to control the electric current, the capacitance is arranged on a boundary of the pixels arranged adjacent to each other in a longitudinal direction of the pixels, the transistor is connected between the power source line and the organic EL element, the capacitance is connected between the transistor and the video signal line, one electrode of the capacitance is connect to the video signal line, another electrode is connect to a gate electrode of the transistor, one electrode which constitutes the capacitance is continuously formed between the pixels arranged adjacent to each other in the longitudinal direction of the pixels, and another electrode which constitutes the capacitance is separately formed between the pixels arranged adjacent to each other in the longitudinal direction of the pixels.
