FILM AND DISPLAY DEVICE USING THE SAME

摘要

<P>PROBLEM TO BE SOLVED: To inexpensively provide a lenticular film which has a large area and a detailed and uniform pitch and which has an optical absorption layer for improving a contrast ratio by using a melt extrusion process. Ž<P>SOLUTION: This film includes at least a structure in which a resin A and a resin B are laminated alternately in the film width direction. The resin B contains an optical absorption agent. The unevenness where the layer (A layer) 1 made of the resin A is projected and the layer (B layer) 2 made of the resin B is recessed is formed on at least one film surface in the film longitudinal direction. The lenticular film satisfies the formula of 1.2≤h(a)/h(b)≤10. In the formula, h(a) is the thickness of the A layer and h(b) is the thickness of the B layer. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
