Abstract: A solar cell module is provided with a solar cell, a sealing member embedding the solar cell therein, a front surface protective member, and a back surface protective member. The storage modulus of the sealing member for the temperature range of 20-40° C. is from 6×107 Pa to 1×109 Pa (inclusive), and the average linear expansion coefficient, which is the average of linear expansion coefficients in the length direction and in the width direction when the temperature of the back surface protective member is changed from 20° C. to 25° C., is 40 ppm/° C. or less. A solar cell protective sheet is a laminate wherein an adhesive layer contains a (meth)acrylic polymer including functional groups reactive with carboxyl groups is laminated on the surface of a transparent resin sheet formed from at least one light-transmitting resin material selected from (meth)acrylic resins, polycarbonate resins and fluororesins.

Abstract: An unwarped, lightweight solar cell module with excellent durability in a thermal cycling test and a humidity freeze test is provided. The solar cell module includes: a solar cell; a sealing member for having the solar cell embedded; a front surface protection member; and a back surface protection member. The back surface protection member includes a plate-like structure (a) including a fibrous reinforcement material with a thickness of 6 mm or less and with a mean linear expansion coefficient of 40 ppm/° C. or less at a temperature of 20 to 25° C., and the front surface protection member includes a plate-like structure (b) including a light-transmitting resin material with a thickness of 0.03 mm or more and 0.6 mm or less.

Abstract: An actinic-energy-ray-curable resin composition (10) is supplied to the nip between a roll-shaped die (7) obtained by subjecting the peripheral surface of a roll-shaped metal member to blasting to thereby form a finely roughened structure and a filmy light-transmitting substrate (9) disposed along the peripheral surface of the roll-shaped die (7), thereby forming the actinic-energy-ray-curable resin composition (10) into a thin film. The finely roughened structure in the peripheral surface of the roll-shaped die (7) is transferred to a surface of the thin film. This actinic-energy-ray-curable resin composition (10) is cured to form a light-transmitting thin film. This film is bonded to the surface of the light-transmitting substrate (9) to obtain an antiglare film. That surface of the light-transmitting thin film which has the finely roughened structure has an arithmetic average inclination angle of 0.5-3.5 degrees.

Abstract: Provides a light polarizing sheet which is easy to manufacture, offers the functionality of conventional multiple sheet structures, and satisfies both the luminance and viewing angle characteristics required for liquid crystal televisions and the like. The light polarizing sheet of the present invention comprises a first polarizing lens sheet including a sheet-shaped substrate and a first lens portion formed on one face of the substrate; and a second polarizing lens sheet including a sheet-shaped substrate and a second lens portion formed on one face of the substrate, having a flat portion on its tip; wherein the flat portion of the second lens portion on the second polarizing lens sheet and the other face of the substrate of the first polarizing lens sheet are adhered using a transparent material.

Abstract: A prism sheet provided with an elongated prism formed surface (41) on which a plurality of elongated prisms (411) extend in parallel to each other. The elongated prism formed surface (41) has roughened portions (412) each having a width W 0.04 to 0.5 times the arranging pitch P of the elongated prisms and arranged between adjacent elongated prisms (411). The surface of the roughened portion (412) has a center-line average roughness Ra of 0.3-2 ?m and a ten-point average roughness Rz of 1-3 ?m, and the prism surface (411a, 411b) of elongated prism has a center-line average roughness Ra of less than 0.3 ?m and a ten-point average roughness Rz of less than 1 ?m.
