Abstract
A display apparatus is disclosed. The display apparatus includes a display including an active area for displaying an image and a black matrix adjacent to the active area, and an optical sheet attached onto the display. The optical sheet includes a Fresnel pattern formed on the black matrix and a portion of the active area. The Fresnel pattern includes a plurality of peaks and a plurality of valleys, which are formed such that depths between the peaks and the valleys gradually increase from the active area to the black matrix. Therefore, it is possible to view an image in front of the black matrix, on which an image is not actually displayed.
