MICROLOUVER ADHESIVE SHEET AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a microlouver sheet resolving both problems of moire formation due to periodicity of an arrangement of light absorption parts of a microlouver layer and generation of shading irregularity due to coarse/dense arrangement and facilitating the attachment to a body to be attached, and an image display device using the same.

SOLUTION: A microlouver adhesive sheet 10 includes: a microlouver layer 1 comprising light absorption parts 2 and light transmission parts 3; and a transparent adhesive layer 4. A light-shielding pattern 2P that is a planar-view shape of the light absorption parts is formed of multiple boundary segments L that define multiple opening areas corresponding to the light transmission parts and extend between two branch points B to define the opening areas. An average value N of the number of boundary segments extending from one branch point is 3.0≤N<4.0. The microlouver adhesive sheet is formed by including a region in which there is no direction where the opening areas are aligned in a fixed repeated period. The image display device includes the microlouver adhesive sheet.
