Abstract: An image display apparatus includes a display, a signal processing device spaced apart from the display to transmit power and a video signal to the display, a plurality of cables configured to transmit power and the video signal from the signal processing device, and an optical sheet attached to the cables. The optical sheet includes a Fresnel pattern formed on the plurality of cables and transparent partition walls formed between the plurality of cables. The Fresnel pattern includes a plurality of peaks and valleys and differences in depth between the peaks and the valleys are decreased from the cables to the transparent partition walls. Therefore, the cables provided between the display and the signal processing device appear transparent.

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.
