ABSTRACT:
The invention compensates for variations of a driving transistor Tr1. The invention provides a pixel circuit including a current-type driven element L, a driving transistor Tr1to control the amount of electrical current to be supplied to the driven element, a capacitor element C connected to the gate of the driving transistor, a switching transistor Tr3connected to the gate of the driving transistor, a switching transistor Tr1, a scanning line S connected to the gate of the switching transistor Tr3, a data line D connected to the source or the drain of the switching transistor Tr3, and a power-supply line V connected to a signal line via the switching transistor Tr3. A diode-connected compensating transistor Tr4is disposed between the power-supply line V and the switching transistor Tr3.
