<p>A pixel circuit (20) includes: an organic EL element (25), a drive TFT (21), and a switching TFT (23) arranged between a gate and a source of the drive TFT (21). While writing to the pixel circuit (20), an initial voltage is applied to the gate terminal of the drive TFT (21) and the switching TFT (23) is controlled to be temporarily conductive while the drive TFT (21) is in a conductive state. A data voltage corrected by using the gate terminal potential of the drive TFT (21) at that moment is applied to the gate terminal of the drive TFT (21). A human being has a high sensitivity for a chromaticity difference of the blue color but a low sensitivity for a chromaticity difference of the green color. An initial voltage Vint_B having a highly accurate threshold value correction for the pixel circuit of the blue color while an initial voltage Vint_G having a low power consumption is used for the pixel circuit of the green color. This, it is possible to provide a current drive type color display device exhibiting a high image quality and requiring a low power consumption.</p> |
