Image display device

An image display device having an image display unit that displays an image, the image display unit including a plurality of display pixels to each of which a driving signal and a scan line signal from a scan line driver are supplied, and the image display device, comprising:

• a correction value memory storing uneven luminance correction values for the respective display pixels;
• a test signal supply unit supplying a predetermined test signal as the driving signal to the display pixels;
• a current measuring unit which measures a current flowing through the scan line driver when said test signal supply unit supplies the test signal to each of the display pixels;
• and
• a control unit which executes, at a predetermined timing, an update operation including:
• sequentially supplying the test signal from said test signal supply unit, part of the display pixels of said image display unit being supplied with the test signal at one supply operation;
• measuring the currents flowing through the scan line driver by said current measuring unit;
• and
• updating the uneven luminance correction values in said correction value memory based on a result of the measurement of the currents, wherein said control unit executes the update operation of the uneven luminance correction values a plurality of times to update the uneven luminance correction values for all the display pixels of said image display unit.
