<p>A pixel circuit 20 includes an organic EL element 25, a driving TFT 21, and a switching TFT 23 provided between the gate and source of the driving TFT 21. Upon writing into the pixel circuit 20, an initial voltage is applied to the gate terminal of the driving TFT 21, and the switching TFT 23 is temporarily controlled to a conducting state while the driving TFT 21 is in a conducting state, and a data voltage corrected using a gate terminal potential of the driving TFT 21 obtained at that time is applied to the gate terminal of the driving TFT 21. The human is sensitive to blue chromaticity differences but is insensitive to green chromaticity differences. An initial voltage Vint_B that increases the accuracy of threshold correction is used for blue pixel circuits, and an initial voltage Vint_G that reduces power consumption is used for green pixel circuits. By this, a current-driven type color display device with high image quality and low power consumption is provided.</p> |
