Abstract
An image display device includes a display panel that includes a plurality of subpixels and selectively displays the 2D image and the 3D image, and a patterned retarder that is positioned in front of the display panel and divides light from the display panel into light of a first polarization and light of a second polarization when the 3D image is displayed. Each subpixel includes a main subpixel including a first pixel electrode receiving a data voltage through a data line and a common electrode receiving a common voltage through a common line, and a subsidiary subpixel including a second pixel electrode receiving the data voltage through the data line, a common electrode positioned opposite the second pixel electrode, and a discharge thin film transistor (TFT) selectively connecting the second pixel electrode to the common electrode based on a displayed image.
