<P>PROBLEM TO BE SOLVED: To provide a pixel circuit capable of canceling an influence of mobility of a drive transistor. <P>SOLUTION: The pixel circuit 2 includes at least a sampling transistor Tr1, the drive transistor Trd, pixel capacity, and a light emitting device EL, in the sampling transistor, a gate is connected to a scanning line, one of either a source or a drain is connected to a signal line, the other of either the source or the drain is connected to a gate of the drive transistor, in the drive transistor, one of either a source or a drain is connected to one end of the light emitting device, the pixel capacity is connected between the gate and one of either the source or the drain of the drive transistor, while signal potential is supplied from the signal line to the gate of the drive transistor, the potential of one of either the source or the drain of the drive transistor is brought close to the signal potential by current flowing through the drive transistor Trd to the power supply of which the other of either the source or the drain is connected. <P>COPYRIGHT: (C)2009,JPO&INPIT |
