Abstract

Disclosed is a liquid crystal display apparatus (600) having enhanced axial brightness as well as embodying a thin and lightweight LCD. A first light (L1) generated from a light source (120) is incident to a light guiding plate (200). A path of the first light is changed by the light guiding plate (200), and a third light (L3) exits toward a reflecting plate (300). Then, the third light (L3) is reflected on the reflecting plate (300) to be changed into a second light (L2) with enhanced axial brightness. The third light (L3) is converged to be the second light (L2) with enhanced axial brightness by the reflecting late (300) with a surface structure having a triangular prism shape. Thus, the liquid crystal display apparatus is capable of enhancing the axial brightness as well as minimizing the overall dimension and weight.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device (LCD) for enhancing axial brightness and realizing a thin and light LCD. Background technique [0002] In recent years, information processing devices have been rapidly developed to have various forms, functions, and faster information processing speeds. Such an information processing device requires a display that displays processed information. [0003] A typical approach is to use a CRT (cathode ray tube) type display as a display device, but recently developed a liquid crystal display device that is smaller in weight and volume than a CRT type display, and has thus become the most popular computer monitor, indoor wall-mounted TV computers and display devices for other information processing devices. [0004] Generally, a liquid crystal display device applies a voltage to a liquid crystal having a specific molecular arrangemen...
