<p>An electrooptic element (ELD) is connected between a first power wiring (Vcom) and the second conduction terminal (D) of a drive transistor (21). This drive transistor (21) has its first conduction terminal (S) connected with a second power wiring (Vp) and its second conduction terminal (D) connected through a first switching transistor (22) with the control terminal (G) of the drive transistor (21). The first switching transistor (22) has its control terminal (G) connected with a control wiring (Wi). The drive transistor (21) has its control terminal (G) connected through a first condenser (C1) with a node (K), which is connected through a second switching transistor (23) with a data line (Sj). The second switching transistor (23) has its control terminal (G) connected with a scanning line (Gi), and the node (K) is connected with a third power source wiring (Vref) through a second condenser (C2). The constitution thus made realizes a pixel circuit (Aij20) for setting the period, for which the threshold voltage of the driving TFT (21) is compensated, freely, and for reducing the power consumption.</p> |
