摘要：An optical sheet is formed by laminating, by co-extrusion molding, a first layercontaining a polycarbonate resin, a second layer containing a polyamide resin, and a third
layer, wherein the second layer is laminated between the first layer and the third layer,the first layer and second layer, and the second layer and third layer can each be peeledat the interface, and the outer surface of the first layer has a fine grooved structure. Theoptical sheet, which is provided with a plurality of layers in such a way, is capable ofretaining, a sufficient amount of heat in a laminate in a mold since the entire sheet can bemade thick during melt extrusion molding, and is able to improve the transferability ofthe fine grooved structure. In addition, the optical sheet can be made thinner by usingonly the peeled first layer as an optical sheet.
