An image display device includes a display panel, a scan driver a data driver, a refresh circuit and a timing controller. The display panel includes a plurality of pixels activated through a plurality of scan lines, and an image data signals are provided through a plurality of data lines. The image data signals to are stored as pixel voltages in the pixels. The refresh circuit is configured to sense the pixel voltages through the data lines and to output one of a first refresh voltage and a second refresh voltage to each of the data lines, to refresh the respective pixel voltage. The timing controller is configured to control the scan driver, the data driver and the refresh circuit.
