Patent attributes
A light guide plate including a transparent light guide substrate and a micro-structural reflective film is provided. The transparent light guide substrate has a light-emitting surface, a bottom surface opposite to the light-emitting surface, and at least one light incident surface connecting the light-emitting surface and the bottom surface. The micro-structural reflective film is disposed below the bottom surface of the transparent light guide substrate and includes a micro-structural layer and a reflective material layer. The micro-structural layer has a plurality of micro-structures, and the reflective material layer covers the micro-structures of the micro-structural layer. Only top ends of the micro-structures and the reflective material layer are laminated on the transparent light guide substrate, such that there is an air gap between the transparent light guide substrate and the micro-structural reflective film. Furthermore, a light-emitting apparatus having the light guide plate is also provided.
