Abstract
A driving circuit in a display apparatus includes a current driving unit for supplying a driving current in a forward direction to a light emitting element based on control data. The current driving unit is furnished with a function of supplying a predetermined current in a reverse direction to the light emitting element. The driving circuit further includes a voltage comparing unit for judging whether a reverse voltage necessary to supply the predetermined current in the reverse direction is smaller than a predetermined voltage. The driving circuit notifies an abnormal condition of the light emitting element based on a judgment by the voltage comparing unit. Consequently, it is possible to detect a light emitting element generating a leak current in a reverse direction of the light emitting element even when the light emitting element is connected to the driving circuit.
