Abstract: An optical sheet is formed by laminating, by co-extrusion molding, a first layer containing 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 peeled at the interface, and the outer surface of the first layer has a fine grooved structure. The optical sheet, which is provided with a plurality of layers in such a way, is capable of retaining, a sufficient amount of heat in a laminate in a mold since the entire sheet can be made thick during melt extrusion molding, and is able to improve the transferability of the fine grooved structure. In addition, the optical sheet can be made thinner by using only the peeled first layer as an optical sheet.

Abstract: The optical sheet according to the present invention includes a first layer containing a polycarbonate resin and a second layer containing an amorphous polyamide resin, the first layer and the second layer being layered by coextrusion molding. The first layer and the second layer are peelable from each other; and a surface of at least one of the first layer and the second layer has a fine uneven shape formed thereat. Such an optical sheet including a plurality of layers can make the entirety sheet thick at the time of melt extrusion molding, and therefore the layered body during the molding can hold a sufficient amount of heat. This improves the transferability of the fine uneven structure. In addition, the layers may be peeled off so that one of the layers is used. In this case, the optical sheet can be made thinner.
