Patent ID: 8836613

Claim:
A stereoscopic image display comprising: a display panel configured to selectively display a 2D image and a 3D image, the display panel including a plurality of pixels; and a patterned retarder configured to divide light from the display panel into first polarized light and second polarized light, wherein each of the plurality of pixels includes: a main display unit including a first pixel electrode connected to a data line through a first thin film transistor (TFT) and a first common electrode which is opposite to the first pixel electrode and is connected to an upper common line; an auxiliary display unit including a second pixel electrode, which is connected to the data line through a second TFT and is connected to the upper common line through a discharge control TFT, and a second common electrode which is opposite to the second pixel electrode and is connected to the upper common line; and a line unit disposed between the main display unit and the auxiliary display unit, the line unit including a gate line, through which a scan pulse is commonly applied to the first TFT and the second TFT, and a discharge control line, through which a discharge control voltage is applied to the discharge control TFT, wherein a lower common line, through which a common voltage is applied to the upper common line, is formed to the outside of the main display unit and the auxiliary display unit, wherein the first TFT and the second TFT are formed on the gate line, and wherein a first storage capacitor of the main display unit, a second storage capacitor of the auxiliary display unit, and the discharge control TFT are formed on the discharge control line.
