Abstract: A 3-dimensional image display device includes a signal controller, a data driver, a display panel, and glasses. The signal controller includes a reference gamma data generator to correct image data. The data driver includes a gray voltage generator to generate a gray voltage based on the corrected image data. The display panel displays left-eye and right-eye images based on a data voltage from the data driver. The lenses of the glasses are controlled by a glasses synchronization signal from the signal controller, to compensate for charging rates of the left-eye and right-eye images.
