Abstract
An image display apparatus includes a current-controlled light emitting; a transistor which controls a first current flowing through the current-controlled light emitting diode, based on a first voltage applied between the gate and the source of the transistor at a light emitting phase; a capacitor arranged between the gate and the source. The image display apparatus also includes a current determining unit which controls a second current flowing between the source and the drain, based on a third voltage applied thereto at the writing phase. The second voltage is written in the capacitor at a writing phase and depends on the second current.
