Provided is a low-cost method for easily forming a transparent conductive pattern that has a low electrical resistance and high transparency, and that is highly invisible to the eye. The method for forming a transparent conductive layer pattern includes the steps of (1) detachably forming a transparent conductive layer on a substrate; (2) then forming, on a support, a negative-patterned heat-sensitive adhesive image; (3) bonding the substrate to the support so that the transparent conductive layer and the heat-sensitive adhesive layer are in close contact with each other; (4) forming a pattern of the transparent conductive layer on the substrate by detaching the support from the substrate to transfer a portion of the transparent conductive layer, the portion being in close contact with the heat-sensitive adhesive layer, to the heat-sensitive adhesive layer; and (5) fixing the transparent conductive layer on the substrate by applying a coating material for a protective layer onto a front surface of the substrate on which the pattern of the transparent conductive layer is formed and impregnating the transparent conductive layer with the coating material.

Provided is a prism sheet which has high effects of suppressing Moir&#xe9; fringes, high front luminance and reduced number of components when it is used as a prism sheet for a backlight unit for a liquid crystal display device. The prism sheet has a prism row having ridges formed in parallel to each other at equivalent intervals on one surface and a light diffusion layer containing porous particles on the other surface. The prism sheet preferably has the prism row on one surface and the light diffusion layer on the other surface by having a light-transmissive substrate in between.
