Abstract
A switching transistoris provided between a gate terminal of a driving TFTand a drain terminal thereof. A first capacitoris provided between the gate terminal of the driving TFTand a source terminal thereof. The current control terminal of the driving TFTis connected to a first terminal of a second capacitor. A second terminal of the second capacitoris connected to the drain terminal of the driving TFTvia a switching transistor, and to a predetermined voltage line Va via a switching transistor. This allows restraint of variation of a current flowing, during a non-selection period, through a current driving light emitting element of a display apparatus, the current variation being caused by threshold voltage variation and mobility variation of the driving TFT. A specific example of the display apparatus including such a current driving light emitting element is an organic EL display apparatus.
