Abstract: An anti-glare member prevents reflection of external light by surfaces of displays or screens without causing reduction of contrast and glare of displayed images. The anti-glare member has an anti-glare layer comprising microparticles and a transparent binder wherein the microparticles are black microparticles having a value (n), obtained by dividing absolute value of complex index of refraction of the black microparticles by index of refraction of the transparent binder, of 0.95 to 1.05. The arithmetical mean roughness (Ra) according to JIS B0601:2001 of surface of the anti-glare layer is 0.3 to 1.0 ?m.

Abstract: An anti-newton ring sheet is provided with an uneven layer. The uneven layer is formed by tightly arranging a plurality of structures in a lattice-like formation. The structures are substantially formed with a polymer resin and have a peak. Here, the axis extending in the vertical direction when the sheet is viewed in plan is the x-axis, and the axis extending in an orthogonal direction to the x-axis is the y-axis. In addition, an arbitrarily defined structure from the structures forming the uneven layer is a base structure, and structures that are adjacent to the base structure along the x-axis and the y-axis are other structures. The uneven layer is formed in a manner such that the height of a vertical section along the direction (x-direction, y-direction) of straight lines connecting the peak of the base structure and the peaks of the other structures periodically changes.

Abstract: An anti-Newton ring sheet can be used for touch panels of various display screens such as those of high definition CRTs and FPDs used in recent years, and so forth. The anti-Newton ring sheet of the can include a plurality of structural rows 2 disposed side by side with a pitch, and heights of the structural rows can vary along extending directions of ridgelines thereof. The heights of the structural rows can vary periodically, and period of the variation can be in the range of 20 to 4000 ?m.

Abstract: A method for manufacturing a thin functional member having no base material, which exhibits a special function and is free from curling caused by the base material. The method includes the following steps (1) to (4): (1) filling a functional layer comprising an ionizing radiation curable resin between a base material and a mold having a predetermined concavo-convex pattern, (2) irradiating the filled functional layer with ionizing radiation to half-cure the functional layer, and then delaminating the functional layer and the base material from the mold, (3) adhering an adhesive sheet to a part of the functional layer, and delaminating the functional layer from the base material starting from a portion to which the adhesive sheet is adhered, and (4) irradiating the functional layer with ionizing radiation again to further cure the functional layer.
