Abstract

Disclosed are an optical sheet, a filter including the same, and an image display device including the optical sheet or the filter. The optical sheet includes a light transmission portion including a plurality of grooves spaced apart from each other at an end of the light transmission portion corresponding to an image light source side or an observer side; and a plurality of external light absorption portions which fill the grooves and include a light absorbable material, wherein at least one part of each of the grooves that is not filled with external light absorption portion forms a recess portion having one open side, and a difference Δd between maximum depths of two recession portions that are adjacent to each other among the recession portions satisfies the following condition: 0.01 ㎛ ≤ |Δd| ≤ 1 ㎛.
