    摘要： The present invention permits a capacitance value of an electro-optical element such as organic EL element to be arbitrarily set without changing the light extraction efficiency of a pixel. That is, the present invention permits a capacitance value Coled of an organic EL element (21) to be arbitrarily set by adjusting the light emission area of the organic EL element (21) without changing the light extraction efficiency of a pixel (20) in an organic EL display device. The organic EL display device has the pixels (20) arranged in a matrix form. A light extraction opening (56) is formed on the surface of the pixel with a light-shielding film (black matrix) (57). The light extraction opening (56) has an opening area smaller than the light emission area of the organic EL element (21).

    摘要： A pixel circuit is disclosed. The pixel circuit includes, at least a drive transistor; an input transistor; a first switching transistor; a second switching transistor; a retention capacity; and an electro-optic device. The retention capacity is connected, at both ends, to a gate node and a source node, respectively, of the drive transistor. The electro-optic device has rectification properties, and is determined in intensity by a value of a drive current coming from the drive transistor whose source node is connected to an anode thereof. The input transistor is connected, at one current end, to the gate node of the drive transistor, and samples a video signal to the retention capacity during a predetermined sampling period. The first switching transistor is turned on before the sampling period, and connects the gate node of the drive transistor at a predetermined reference voltage.
