OPTICAL SHEET, CAPABLE OF IMPROVING A HANDLING PERFORMANCE BY BEING PROTECTED FROM EXTERNAL FORCE OR ROUGH SURFACES

摘要

PURPOSE: An optical sheet is provided to be cost-effectively manufactured and improve the manufacturing efficiency by preventing the reduction of the illuminance.;CONSTITUTION: A light diffusing layer including a binder resin and light diffusing particles is formed on at least one base layer(10). A light collecting layer(40) is formed on the light diffusing layer and is composed of a curable resin. The surface of the light collecting layer is structured. Resin curing layers(50, 60) are formed on the light collecting layer and contain elements including branch chains with the slip characteristic.;COPYRIGHT KIPO 2011
