Abstract
An image display device includes a luminescence element, a first capacitor, a driver having a gate connected to a first electrode of the first capacitor and a source connected to an anode of the luminescence element, and a second capacitor connected to a second electrode of the first capacitor. A power source supplies a reference voltage to the first electrode of the first capacitor via a first switch. A data line supplies a signal voltage to the second electrode of the first capacitor via a second switch. A third switch connects the anode of the luminescence element to the second capacitor. A controller supplies the signal voltage to the first capacitor by switching ON the first and second switches when the third switch is OFF, switches OFF the first and second switches to switch ON the third switch, and causes the second capacitor to hold a source potential of the driver while the third switch is ON.
