Title: ANTIGLARE HARDCOAT FILM
Abstract:
To provide an antiglare hardcoat film having a transparent plastic film base material and an antiglare hardcoat layer formed on the film, which can suppress the reduction of the display contrast of a display while maintaining the antiglare property thereof. An antiglare hardcoat film (4) comprising a transparent plastic film base material (1) and a hardcoat layer (2) containing fine particles (2b) and having an irregular surface provided on at least one face of the material (1), characterized in that the particles (2b) have an average particle diameter of 6 to 15 μm, an average slope angle (θa) of the irregular shape formed by the fine particles (2b) is 0.4 to 1.5˚, and the relationship of (a contrast ratio)/(a contrast ratio of a hardcoat film containing none of the fine particles) x 100 ≥ 60 % is satisfied.
