The present invention relates to a lens unit and an image display apparatus including the same. The image display apparatus includes a display and a lens unit disposed at the front surface of the display and selectively refracting a path of light from the display. The lens unit includes a first electrode, a second electrode, a first medium of an anisotropic material between the first electrode and the second electrode, a polarization output unit converting light from the display into first directional polarization light and outputting the light or second directional polarization light and outputting the light according to power applied between the first electrode and the second electrode, and a lens sheet where a Fresnel lens form of a second medium is formed in a concave form and a third medium is disposed in the concave form. As a result, a 2D image and a 3D image may be selectively viewed. [Reference numerals] (AA) 3D mode; (BB) 2D mode |
