Abstract: An optical prism sheet having surface roughness is provided to improve light diffusion and transmission properties and to reduce a manufacturing cost by not using a diffusion sheet. An optical prism sheet includes a light refraction unit(210). The light refraction unit is formed on one surface of a base film(200) and composed of a plurality of unit prisms(211) having predetermined cross sections. Fine unevenness having predetermined surface roughness is formed on a surface of the light refraction unit. A unit surface area of the light refraction unit, where the fine unevenness is formed, is in a range of 1.1 to 100 times of the unit surface of the light refraction unit, where the fine unevenness is not formed.

Abstract: A filter and a plasma display panel are provided to effectively shield an EMI(Electromagnetic Interference) and improve a contrast ratio by mixing a black bead and an EMI shielding material into an external beam shielding portion. A filter includes a transparent substrate(111), an anti-reflection layer(113), a near IR(InfraRed) ray shielding layer(115), and an optical film(120). The transparent substrate passes an inlet visual ray. The anti-reflection layer is formed on one surface of the transparent substrate and prevents a reflection of the external ray. The near IR ray shielding layer is formed on one side of the transparent substrate and blocks an inlet near IR ray. The optical film is formed on at least one surface of the transparent substrate and includes a focusing portion, an external ray shielding portion, plural black beads, and an EMI(ElectroMagnetic Interference) shielding material. The focusing portion focuses the inlet visual ray. The external ray shielding portion is made of a material with a refractive index lower than the focusing portion. The black beads and the EMI shielding material are mixed into the external ray shielding portion.

Abstract: An optical sheet with a photo-sensitive coating layer for improving adhesion is provided to enhance adhesion between an optical member and a photocurable coating layer and to minimize environmental pollution by forming a photo-sensitive resin layer between the optical member and the photocurable coating layer. An optical sheet(10) comprises an optical member(100), a photocurable coating layer(120), and a photo-sensitive resin layer(115) between the optical member and the photocurable coating layer. The photo-sensitive resin layer includes a photopolymerization initiator 0.1~20 parts by weight and a binder polymer 20~80 parts by weight for photopolymerization monomer and oligomer 100 parts by weight. The photopolymerization monomer and oligomer is at least any one selected from a group consisting of acrylate, epoxy acrylate, urethane acrylate, polyester acrylate, and bisphenol derivatives.
