Disclosed is an organic LED device capable of coping with a large area and an efficient manufacturing method thereof. An organic LED device of the present invention is constituted by including a driver TFT and a switching TFT, which are formed on an insulating substrate. Furthermore, an organic LED element is formed, for each pixel, on the substrate with an insulating film interposed therebetween and is connected to the driver TFT. The organic LED device of the present invention includes an anode and a cathode connecting the driver TFT and the organic LED element formed on the insulating film to each other. As a common electrode, the anode connects a plurality of pixels to one another, and thus a self-consistency thereof is improved during manufacturing. |
