摘要：
A pixel circuit includes a compensating circuit that detects a decrease in the driving current from an output node side of a drive transistor and feeds back detection results to an input node side of the drive transistor to compensate for a decrease in the driving current, which decrease is attendant on a secular change of the drive transistor.
