Abstract
An image display device includes a display element selectively implementing a 2D image and a 3D image and a patterned retarder. The display element includes a pixel array including a plurality of subpixels, which are respectively formed at crossings of column lines and row lines. The patterned retarder includes a plurality of first retarders, each of which transmits light from the display element as a first polarization component, and a plurality of second retarders, each of which transmits the light from the display element as a second polarization component. The first retarders and the second retarders are alternatively arranged.
