Abstract:
A switching transistor 3 is provided between a gate terminal of a driving TFT 1 and a drain terminal thereof. A first capacitor 2 is provided between the gate terminal of the driving TFT 1 and a source terminal thereof. The current control terminal of the driving TFT 1 is connected to a first terminal of a second capacitor 7. A second terminal of the second capacitor 7 is connected to the drain terminal of the driving TFT 1 via a switching transistor 9, and to a predetermined voltage line Va via a switching transistor 8. 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.
