Patent ID: 8519908

Claim:
An image display device comprising: a display panel including a plurality of red, green, and blue subpixels, the display panel configured to selectively display a 2D image and a 3D image; and a patterned retarder positioned in front of the display panel, the patterned retarder configured to divide light from the display panel into light of a first polarization and light of a second polarization when the 3D image is displayed, wherein each of the plurality of red, green, and blue subpixels includes: a main subpixel including a first pixel electrode receiving a data voltage through a data line and a common electrode that is positioned opposite the first pixel electrode and receives 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 to discharge the data voltage of the second pixel electrode to a common voltage of the common electrode based on a displayed image.
