Abstract

Disclosed is a liquid crystal display having a prism sheet. The prism sheet includes a base and a plurality of prism mountains. The base includes a front surface and a rear surface facing the front surface. The prism mountains are integrally formed with the base on the rear surface of the base. At least one prism mountain includes a plurality of light incidence surfaces and a reflective surface. The light incidence surfaces receive light. The reflective surface is adjacent to one of the light incidence surfaces to reflect the light. A vertical angle of the prism mountains formed between the light incidence surface adjacent to the reflective surface and the reflective surface, is in a range of about 70 DEG to about 100 DEG.

Description

[0001] This application claims priority from Korean Patent Application No. 2008-83455 filed on Aug. 26, 2008, the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a liquid crystal display. More particularly, the present invention relates to a liquid crystal display having a prism sheet capable of exhibiting high light collection efficiency. Background technique [0003] Recently, as various electronic apparatuses such as mobile phones, PDAs (Personal Digital Assistants), computers, and large-sized televisions have been developed, demands for flat panel display apparatuses suitable for the electronic apparatuses are also increasing. [0004] Flat panel display devices such as LCD (Liquid Crystal Display), PDP (Plasma Display Panel), FED (Field Emission Display), VFD (Vacuum Fluorescent Display), EPD (Electrophoretic Display), etc. have been actively studied. At present, among them, LCDs are attracting attention...
