Abstract: A source of a driving transistor for driving an organic EL element functions as a first capacitance electrode layer. A second capacitance electrode layer is formed on the source through a gate insulating film of the driving transistor. The second capacitance electrode layer is formed with the same layer and by the same process as the gate electrode. A third capacitance electrode layer is formed extending over the second capacitance electrode layer through the interlayer insulating film. The third capacitance electrode layer is formed with the same layer as the drain electrode and the drain signal line. The third capacitance electrode layer is connected to the source of the driving transistor. The forming area of the storage capacitance element for holding the video signal supplied to the gate of the driving transistor can be thus reduced, improving display quality as well as extending life span of the organic El element.

The TFT and the element to be driven are electrically connected by a wiring layer. The contact position between the wiring layer and the TFT and the contact position between the wiring layer and the element to be driven are positioned so as to be distant from each other. Alternatively, at least the contact hole region of a first electrode of the element is covered by a flattening layer. With this structure, it is possible to realize a flatter surface on which to form, for example, the emissive layer of the element to be driven.

Of the inverter circuits, only necessary inverter circuits are selected and connected, thereby delaying the sampling timing for a video signal. The connection between the inverter circuit and the signal path is achieved simply by changing a connection line pattern mask in accordance with the number of inverter circuits to be connected, and without changing other manufacturing processes.

More specifically, of opposing first and second sides of a pixel, in a section where the first TFT is connected to the data line, the driving power supply line is placed on the second side, being the side opposite the data line, and in a section where the second TFT is connected to the driving power supply line, the driving power supply line is placed on the first side. In this manner, pixels provided in positions shifted for each row can be connected with a simple wiring layout.

Abstract: The pixel portion of the display device of this invention has the emissive portion including the organic EL element and the circuit portion including the pixel selection TFT and the driving TFT. The cathode layer C1, which is disposed on the emissive portion, is utilized only as the cathode of the organic EL element. The wiring layer made of the same layer as the cathode layer is separated from the cathode layer, and electrically insulated from cathode layer. The wiring layer, which is disposed on the pixel portion, is utilized for other than the cathode. The location to divide the wiring layer from the cathode layer C1 is above the circuit portion in order to prevent the lowered open aperture. Therefore, it is possible to increase the number of the signal lines and source lines without lowering the open aperture.
