  • Patent number: 8758877
    Abstract: An antiglare hard coat film is provided in which light transmittance is high without giving antiglare properties more than necessary, a haze value is low, transparency is excellent, image clarity is high, glare of an image is suppressed, whitishness (white blur) of the film is reduced, contrast deterioration is suppressed, and visibility of the display is improved as compared with prior-art antiglare films. This antiglare hard coat film is formed by providing an antiglare hard coat layer containing organic particulates and a resin on a transparent film. When an average value of height in an evaluation region on the surface of the antiglare hard coat film is set to zero (0), a maximum sectional height represented by a difference between a height maximum value in the evaluation region and a height minimum value in the evaluation region is 0.6 ?m or less.
