Abstract

A optical element covering member includes one or more optical elements, a support medium for supporting the one or more optical elements, and a cover material for covering the one or more optical elements and the support medium. The cover material includes a layer of block copolymer of vinyl aromatic hydrocarbon and conjugate diene, and a mass ratio of the vinyl aromatic hydrocarbon to the conjugate diene stands at 95:5 to 5:95.

Description

Optical element covering member, backlight, and liquid crystal display device Cross References to Related Applications The present invention contains subject matter of Japanese Patent Application No. 2007-103347 filed in the Japan Patent Office on Apr. 10, 2007, the entire content of which is hereby incorporated by reference. technical field The invention relates to a covering body structure of an optical element, a backlight member having the covering structure of the optical element, and a liquid crystal display device. More specifically, the present invention relates to a cladding structure of an optical element for improving display characteristics of a liquid crystal display device. Background technique In order to improve viewing angles, brightness, etc., many optical elements have been used in liquid crystal display devices. These optical elements have a film shape or a sheet shape, such as a diffusion film and a prism sheet. FIG. 10 shows the structure of a l...
