OPTICAL FILM AND BACK-LIGHT UNIT WITH THE SAME

摘要

The present invention relates to an optical film and a back-light unit with the same. The optical film comprises a plurality of first patterns formed on one Surface of the film; and a plurality of second patterns and a plurality of third patterns formed on the other surface of the film, wherein the first patterns have optical sections for scattering incident light, the second patterns have optical sections for emitting the incident light in all directions, and the third patterns are formed along pattern surfaces of the second patterns and have optical sections for emitting the incident light in a substantially vertical direction. According to the present invention, there are provided an optical film and a back-light unit with the same, which can enhance productivity and workability and reduce manufacturing costs and a fraction defective. Further, there are provided an optical film and a back-light unit with the same, which can minimize optical defects such as moire or mottles. Moreover, there are provided an optical film and a backlight unit with the same, which can represent a wide viewing angle and high luminance.
