LIGHT GUIDE PLATE WITH LASER PATTERN

摘要

PURPOSE: A light guide plate with a laser pattern is provided to offer uniform brightness and high optical efficiency by uniformly forming not only a width of a scattering pattern recess but also a gap between scattering pattern recesses. CONSTITUTION: A light source part(13) accepts a light source at one side. A light guide part(11) of a sheet shape is connected to the light source part and scatters light generated in the light source part. A scattering pattern recess(12) is formed on one side of an up and down side of the light guide part or on the up and down side or the light guide part by laser processing. Scattering pattern grooves is formed to have different depths.
