Abstract
An image display apparatus includes a light emitting unit that emits light by current flowing through the light emitting unit; and a driver unit that includes a first terminal and a second terminal. The driver unit has a characteristic that an absolute value of a current flowing through the second terminal increases with a potential of the first terminal to the second terminal, and controls light emission of the light emitting unit based on a potential difference between the first terminal and the second terminal. The image display apparatus also includes a control unit that controls the potential of the first terminal to the second terminal of the driver unit to a value lower than a threshold voltage of the driver unit.
