[0059] (1-1) Structure of liquid crystal display

[0060] figure 1 It is a schematic diagram showing a structural example of the liquid crystal display according to the first embodiment of the present invention. Such as figure 1 As shown, the liquid crystal display includes a lighting device 1 that emits light, an optical package 2 that transmits light emitted from the lighting device 1 and a liquid crystal panel 3 that displays images based on the light transmitted through the optical package 2. The lighting device 1 and the optical package 2 constitute a backlight 4. Hereinafter, with regard to the surface of the optical component such as the optical package 2, the surface on which the light from the lighting device 1 is incident is referred to as the "light incident surface", and the surface from which the light incident on the light incident surface is emitted is It is called the "light emitting surface", and the surface located between the light incident surface and the li...

Abstract

The invention discloses an optical package, a method of manufacturing the same, a backlight, and a liquid crystal display. The optical package includes one or two or more film-like or sheet-like optical elements, a plate-like support which supports the one or two or more optical elements, and a film-like or sheet-like packaging member which covers the one or two or more optical elements and the support. The one or two or more optical elements and the support form a stack, the stack and the packaging member are in close contact with each other, and the packaging member has a shrinkage property or a stretching property and contains voids and a filler disposed in the voids.

Description

Technical field [0001] The present invention relates to an optical package, a method of manufacturing an optical package, a backlight, and a liquid crystal display. More specifically, the present invention relates to an optical package with diffusing properties. Background technique [0002] In the liquid crystal display according to the related art, a plurality of optical elements are used for the purpose of improving the viewing angle, brightness, and the like. For example, as the optical element, a film-like or sheet-like element such as a diffusion film and a prism sheet is used. [0003] Figure 29 The structure of a liquid crystal display according to the related art is shown. Such as Figure 29 As shown, the liquid crystal display includes an illuminating device 101 that emits light, a diffusion plate 102 that diffuses light emitted from the illuminating device 101, a plurality of optical elements 103 that converge or diffuse the light diffused by the diffusion plate 102,...
