Abstract
An image display device comprises an image display panel that displays a 2D or 3D image; a driving circuit that applies a data voltage of a 2D data format for the 2D image or a data voltage of a 3D data format for the 3D image to the image display panel; and a controller that controls the driving circuit according to a 2D mode for displaying the 2D image or a 3D mode for displaying the 3D image, wherein R, G, and B subpixels of the image display panel each comprises first and second fine subpixels divided by one data line and two adjacent gate lines. In the 2D mode, the same data voltage of the 2D data format is applied to the first and second fine subpixels. In the 3D mode, the data voltage of the 3D data format is applied to the first fine subpixel and a black gray voltage is applied to the second fine subpixel.
