Embodiment Construction

[0084] Reference will now be made in detail to an optical film and a display device having the same according to the present invention, embodiments of which are illustrated in the accompanying drawings and described below.

[0085] In the following description of the present invention, when a detailed description of known functions and components included in the present invention may make the subject matter of the present invention unclear, the descriptions will be omitted.

[0086] refer to figure 1, the optical film 10 according to an exemplary embodiment of the present invention is a film designed to prevent a moire phenomenon while reducing color shift in the display device 1 . In an example, the display device 1 employing the optical film 10 may be a liquid crystal display. Here, the optical film 10 may be arranged on the front surface of the liquid crystal display panel 5 having a liquid crystal layer interposed between two opposing substrates. In another example, the...

Abstract

A display device that can reduce color shift and prevent the quality of an image from degrading due to Moire. The display device includes a display panel and an optical film, which includes a background layer disposed in front of the display panel, and a lens section formed on the background layer. The lens section has a plurality of patterns spaced apart from each other to diffuse incident light. The spacing [tau] and pitch T of the patterns are determined by the following m value in the following formulae, and m = P / T, p / P is an aperture ratio of sub-pixels of the display panel, [tau] / T is an aperture ratio of the lens section, I is an intensity of light exiting the optical film after being diffused through the sub-pixels, P and p are a pitch and a width of the sub-pixels, T is a pitch of the patterns, and [tau]=T-W.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority from Korean Patent Application No. 10-2011-0051584 filed on May 30, 2011 and Korean Patent Application No. 10-2011-0060522 filed on June 22, 2011, for all purposes The entire contents of these applications are incorporated herein by reference. technical field [0003] The present application relates to a display device, and more particularly, to a display device capable of not only reducing color shift but also preventing degradation of image quality due to a moiré phenomenon. Background technique [0004] In response to the emergence of a highly developed information society, components and devices related to image display have been greatly improved and spread rapidly. Among these components and devices, image display devices have been widely distributed for televisions (TVs), personal computer (PC) monitors, and the like. Also, attempts are being made to simultaneously increase the s...
