LIGHT GUIDING PLATE AND LIGHT EMITTING APPARATUS THEREOF

摘要

PURPOSE: It forms the diffuse sheet and the light guide plate and the light emitting device for including the light guide plate decentralize the light coming out from the light guide plate. CONSTITUTION: The waveguide(30) guiding the light is formed on the substrate(10). It reflects the light guided according to waveguide and the reflection metal(40) changes the progressive direction of the light. The cladding layer(20) is formed in substrate and between waveguide. The cladding layer comprises the first insulation layer having the first refractive index.
