PROBLEM TO BE SOLVED: To provide an antiglare film provided on the outermost surface from the viewpoint of surface protection in a liquid crystal display device (LCD) and the like, all of antiglare property, anti-white turbidity, image clarity (image sharpness), and antiglare property. An antiglare film having good optical performance is provided. The distribution of uneven portions in a predetermined region of an antiglare film having uneven portions on the entire surface is such that the total area of unit regions having an inclination angle of 3 ° or more is 95% or more of the total area of the predetermined region. When the total area of the unit regions having an inclination angle of 0 ° is α, α is 0.5 to 10% of the total area of the predetermined region. In addition, among the unit regions having other inclination angles within 3 °, the total sum of the unit region areas of the unit regions with frequent inclination angles belonging to the range of 0.9α to 1.1α is the predetermined region. In addition to being 80% or more of the total area, the distribution of the irregularities in the unit area of the frequent inclination angle has a distribution close to a rectangle in the distribution graph of the inclination angle of the irregularities and the number of irregularities. ,preferable.
