Abstract: The present invention relates to an image display device using a diffractive lens. An image display device according to an exemplary embodiment of the present invention includes a display panel displaying an image, and a diffractive lens for the image of the display panel to be recognized as a two-dimensional (2D) image or a three-dimensional (3D) image, wherein the diffractive lens modifies a path of light by using an optical principle of a Fresnel zone plate.

Abstract: A two-dimensional/three-dimensional switchable display apparatus includes: a display panel; a first substrate disposed on the display panel; a first electrode layer disposed on the first substrate and including a plurality of first electrodes; a second substrate disposed on the first substrate; a second electrode layer disposed on the second substrate and including a plurality of second electrodes; and a liquid crystal layer disposed between the first and second substrates. A plurality of lens units are formed in association with a first position of the liquid crystal layer when a lens forming voltage profile is applied to the first electrodes and a common voltage is applied to the second electrodes. When the common voltage is applied to the first electrodes and the lens forming voltage is applied to the second electrodes, the plurality of lens units are formed in association with a second position spaced apart from the first position.
