摘要：A pixel circuit is capable of maintaining a display quality even in cases where an

input transistor has a low mobility, or where it is impossible to take a sufficient selectionperiod for each scanning line. A pixel circuit includes an organic EL element (OLED),transistors, and a capacitor. A drive transistor has its drain terminal connected to a HIGHlevel power supply line, and has its source terminal connected to an anode terminal ofthe OLED. The first input transistor has its gate terminal connected to a scanning line Si,and is disposed between a data line Dj and the gate terminal of the drive transistor. Thesecond input transistor has its gate terminal connected to a scanning line (Si−1) in the(i−1)th row, and is disposed between a data line and the gate terminal of the drivetransistor. The capacitor is disposed between the gate terminal and the source terminalof the drive transistor.
