摘要： When a current-writing type pixel circuit is made, it involves a greater number of transistors and TFTs occupy much of the area of the pixel circuit. To alleviate this problem, two pixel circuits (P1, P2) have a first scanning TFT (14), a current-voltage conversion TFT (16), respective second scanning TFTs (15-1, 15-2), capacitors (13-1, 13-2), and drive TFTs (12-1, 12-2) for OLED including organic EL elements (11-2, 11-2) of two pixels, for example, in a row direction. In each of the pixel circuits, the first scanning TFT (14) handling a large amount of current (Iw) as compare with current flowing through the OLED (11-2, 11-2), and the current-voltage conversion TFT (16) are shared between two pixels.

摘要： In an active-matrix display device and a method for driving the active-matrix display device, a fifth transistor is connected between a power line and a drain terminal of a first transistor so that a power-supply voltage, namely the fixed voltage required for the compensation of the threshold voltage, is supplied by the power line via a fifth transistor and not by a signal line. Thus, a sufficient length of time for the threshold voltage compensation period can be maintained, and a second transistor of each pixel can accurately be compensated for threshold voltage irregularities.
