摘要：
An optical prism sheet includes an optical refracting part including a plurality of unit prisms, the unit prisms each having a predetermined cross-section and being disposed on one side of the optical prism sheet, and fine irregularities having a predetermined roughness and configured to diffuse light, the fine irregularities being on surfaces of the unit prisms and increasing a unit surface area of the optical refracting part by about 1.1 to about 100 times.
