Abstract
To provide an image display device having a circuit for solving burning phenomenon without increasing the size of the circuit. An image display device is provided having a display unit formed using display devices, a signal line for inputting a display signal voltage to the display unit, and a display control unit for controlling the display signal voltage, the image display device comprising a detection power source, a switch for causing a current of the detection power source to flow to the display device, a detection circuit for detecting the current, and a detection information storage circuit for storing information, and compensating the display signal voltage, using the information, wherein using a first reference voltage, and current detection is carried out, the detection circuit feeds back the current detected to set a second reference voltage different from the first reference voltage, and carries out current detection.
