Embodiment Construction

[0020] The invention will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers, films, panels, regions, etc., may be exaggerated for clarity. Like reference numerals in the drawings indicate like elements.

[0021] It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” or “connected to” another element, it can be directly on or directly connected to the other element. One element, or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" ...

Abstract

A light guide for converting a dot light source or a linear light source into a planar light source, and the light guide includes a light emitting surface and a reflection surface facing the light emitting surface and having a plurality of reflection patterns, wherein a width of the reflection patterns is less than 10 mum.

Description

technical field [0001] Exemplary embodiments of the present invention relate to a light guide that converts a point light source or a linear light source into a planar light source. Background technique [0002] In liquid crystal displays, which are passive display devices that display images by controlling light emitted from individual light sources, light guides are used to convert point or linear light sources into planar light sources. [0003] Liquid crystal displays are now widely used as a type of flat panel display. A liquid crystal display has two display panels on which field generating electrodes such as pixel electrodes and common electrodes are formed. The liquid crystal layer is interposed between the panels, and a backlight module is included to provide light to the display panel interposed by the liquid crystal layer. In a liquid crystal display, a voltage is applied to field generating electrodes to generate an electric field across a liquid crystal layer,...
