TRANSPARENT PLASTIC PLATE FOR LIGHT-EMITTING DEVICE, LIGHT-EMITTING DEVICE, AND METHOD FOR MANUFACTURING TRANSPARENT PLASTIC PLATE FOR LIGHT-EMITTING DEVICE

摘要

A transparent plastic plate for a light-emitting device according to a first aspect of the present invention is a transparent plastic plate for a light-emitting device, having a plurality of light reflection grooves formed in a light traveling direction so that light irradiated from a light source installed on a side is reflected and refracted, wherein the depths of the plurality of light reflection grooves gradually increase from a portion adjacent to the light source toward the central portion of the transparent plastic plate, and the light reflection grooves have a white color layer of a certain pattern formed on the inner surfaces thereof.
