OPTICAL PLATE, METHOD OF MANUFACTURING THE SAME AND DISPLAY DEVICE HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an optical plate, a method of manufacturing the optical plate and a display device having the optical plate.

SOLUTION: The optical plate comprises: an incident surface to which light from a lamp disposed on a side part; an emission surface perpendicularly extended from the upper side of the incident surface; and a reflection surface facing the emission surface. A condensing pattern in which each of a plurality of belt-like structures forms concentric circles is formed on the emission surface. The focal pattern has a fresnel shape. A diffusion pattern for diffusion reflection of light is formed on the reflection surface. As a result, an optical sheet such as prism sheet for light condensing can be removed, manufacturing expenses can be reduced and the thickness of a product can be reduced.
