A SINGLE BODY TYPE BACK-LIGHT OF LCD DEVICE AND MANUFACTURING METHOD THEREOF

摘要

An integrated type backlight structure of an LCD device and a manufacturing method thereof are provided to form a light guide plate, a diffusion layer and an optical prism integrally through coating and form an air domain among the light guide plate, the diffusion layer and the optical prism. A light guide plate converts light applied from a light source into a planar light and simultaneously changes a direction of an incident light to emit the light. A diffusion layer(120) is integrally bonded in an upper surface(110a) of the light guide plate so that dispersion of light is blocked between the diffusion layer and the light guide plate and the first closed air domain(A1) is formed. The first closed air domain make light straight. The diffusion layer uniformly diffuses the light which is incident from the first closed air domain by a dispersing effect. An optical prism layer(130) is integrally formed on the diffusion layer. The optical prism layer increases brightness of the light which is inputted from the diffusion layer.
