Title:
TRANSPARENT LIGHT GUIDE PLATE AND LIGHT-REFLECTIVE SHEET USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/209146
Kind Code:
A1
Abstract:
Provided is a light guide plate having sufficiently high uniformity of emitted light volumes and having light-reflective protrusions that are difficult to see and difficult to peel off. This transparent light guide plate reflects incident light from inner spherical surfaces of a plurality of light-reflective protrusions provided on a rear surface thereof and emits said incident light from the surface thereof. This transparent light guide plate comprises a light-transmitting light guide base material, an adhesive layer, and a light-reflective member. The light-reflective member has a base layer and a light-reflective layer. The light-reflective protrusions are formed in the light-reflective layer, by embossing. As a result of forming the light-reflective protrusions by embossing, these light-reflective protrusions can be formed smaller, the radius and pitch of same can be controlled with high precision, and peeling off thereof can be suppressed.
