摘要:
A driving transistor is configured to control driving current for the light-emitting element. A first capacitive element and a second capacitive element are connected in series between a gate and a source of the driving transistor. A first switching transistor is configured to switch connection/disconnection between a data line and an intermediate node located between the first capacitive element and the second capacitive element. A second switching transistor is configured to switch connection/disconnection between the gate and a drain of the driving transistor. A third switching transistor is configured to switch connection/disconnection between the intermediate node and a reference power line. A fourth switching transistor is configured to switch supply/non-supply of driving current from the driving transistor to the light-emitting element. A fifth switching transistor is configured to switch connection/disconnection between an anode of the light-emitting element and a reset power line.
