Abstract:
1. An image display device comprising: a display panel including a plurality of subpixels to selectively configure a 2D image and a 3D image; and a patterned retarder separating the light incident from the display panel into a first polarization component and a second polarization component, wherein, the subpixel includes a main subpixel, a subsidiary subpixel and a control TFT for controlling a display gray level of the subsidiary subpixel, the main subpixel comprising a first liquid crystal cell, a first switch TFT switching on or off a current path between a data line and the first liquid crystal cell in response to a kth scan pulse which is supplied by a kth gate line, and a first storage capacitor formed by an overlap between a first common line, to which a first common voltage is applied, and a pixel electrode of the first liquid crystal cell, the subsidiary subpixel comprising a second liquid crystal cell, a second switch TFT switching on or off a current path between the data line and the second liquid crystal cell in response to the kth scan pulse, and a second storage capacitor formed by an overlap between a second common line, to which a second common voltage is applied, and a pixel electrode of the second liquid crystal cell, the control TFT switching on or off a current path between the second common line and the second storage capacitor in response to a (k+1)th scan pulse which is supplied by a (k+1)th gate line, so as to control display gray level of the subsidiary subpixel, when configuring the 2D image, the first and second common voltage are applied with the same DC voltage level, and when configuring the 3D image, the first common voltage is applied with the DC voltage level, and the second common voltage is applied with a different voltage level from the first voltage.
