Abstract:
1. An image display device comprising: a display panel including a plurality of pixels and configured to operate in a 2D mode and a 3D mode; a patterned retarder including a first retarder and a second retarder for dividing light from the display panel into first polarized light and second polarized light, respectively; and a control voltage generator configured to generate a first DC control voltage of an off-level and a second DC control voltage of a slight-on level, which is higher than the off-level and is lower than a full-on level, and selectively output the first DC control voltage and the second DC control voltage depending on a driving mode, wherein each of the plurality of pixels includes an upper display unit and a lower display unit, which are vertically disposed in a mirror form, wherein the upper display unit includes an upper main display unit and an upper auxiliary display unit which are adjacent to each other, and the lower display unit includes a lower main display unit and a lower auxiliary display unit which are adjacent to each other, and wherein the lower main display unit is disposed on a lower side of the upper main display unit along a vertical direction, and the upper auxiliary display unit and the lower auxiliary display unit are disposed adjacent to each other between the upper main display unit the lower main display unit, the first retarder overlaps the lower display unit in a first pixel and the upper display unit in a second pixel next to the first pixel in a vertical direction.
