UV CURABLE RESIN COMPOSITION, PRISM SHEET OF THE SAME, AND BACKLIGHT UNIT AND LIQUID CRYSTAL DISPLAY DEVICE USING THE SHEET

摘要

PURPOSE: A UV curable resin composition, a prism sheet using thereof, and a backlight unit and a liquid crystal display including the prism sheet are provided to maintain the function of the prism sheet, to improve the Transparency, the refractive rate and the surface hardness of the composition. CONSTITUTION: A UV curable resin composition contains 10~80 parts of (meta)acrylate oligomer by weight marked as chemical formula 1, 10~60 parts of (meta)acrylate monomer by weight, and 10~60 parts of photo initiator by weight for 100 parts of total composition by weight. In the chemical formula 1, X refers to an oxygen atom or a sulfur-atom. Y refers to -CH_2CH(OH)CH_2O-, -CH_2CH_2O- or -CH_2C(CH3)HO -. R refers to a hydrogen atom or an alkyl group with the carbon number of 1~10.
