OPTICAL SHEET AND METHOD FOR FABRICATING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an optical sheet which has a function of diffusing and concentrating light and can prevent a moire phenomenon and to provide a method for fabricating the optical sheet. SOLUTION: The optical sheet includes a prism pattern having a plurality of mountains and ravines and a diffusion pattern irregularly formed on the prism pattern to concentrate and diffuse the light emitted from a light source positioned in the upper part of a light transmission plate. As a result, light can be diffused and concentrated and the moire phenomenon can be prevented by one prism sheet without using a diffusion sheet separately. COPYRIGHT: (C)2008,JPO&INPIT
