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 (P 1 , P 2 ) 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.
