LIGHT GUIDE PANEL OF BACK LIGHT THAT HAVE MULTI FUNCTION

摘要

A light guiding plate for a backlight is provided to realize a simple structure and a small thickness, thereby reducing the productive cost, by coupling sheets having respective functions with a light guiding member in a single body. A prism member(20) is coupled with an upper side of a light guiding member(10), thereby constituting a light guiding plate with a multi-function. A concave-convex pattern part(11) is formed on a lower portion of the light guiding member. A reflective layer(12) is formed on a surface of the pattern part. The reflective layer is formed through sputtering. The prism member has predetermined area and thickness. A grid(21), which has rectangular parallelepiped shape unit prisms, is coupled with a lower portion of the prism member in a single body.
