发明名称 Pixel circuit, electro-optical device, and electronic apparatus
摘要 To prevent degradation of quality of a displayed image by maintaining the flow of current at a constant value even when organic EL elements are degraded, a pixel circuit includes a capacitor that accumulates, when a scanning line is selected, charge in accordance with current flowing through a data line; a TFT that allows, subsequent to the selection, current I2 in accordance with the accumulated charge to flow between the source and drain of the TFT; an organic EL element whose anode is connected to the drain of the TFT; a TFT that detects a voltage applied to the organic EL element and allows current I3 in accordance with the applied voltage to flow between the source and drain of the TFT; and a correction circuit that generates mirror current I4 of the current I3 and adds the current I4 to the current I2.
