Claim Text:
1. An antiglare sheet having an antiglare layer comprising a binder resin, diffusion particles and binder fine particles on at least one side of a transparent base material, the antiglare layer having irregularities on the side opposite the transparent base material, the irregularities being formed by raised sections constituted by the diffusion particles and/or aggregates of the diffusion particles, the diffusion particles being surrounded by a localization layer with high density of the binder fine particles, and the binder fine particles being hydrophobic-treated fumed silica and/or a laminar inorganic compound, wherein the following inequalities (1) and (2) are satisfied to improve blackness in dark surroundings, to improve vivid complexion and blackness, and to prevent an increase of reflection thereby preventing the generation of stray light, wherein Q is a transmission intensity in the direction of regular transmission, when visible light rays have been irradiated on the antiglare sheet perpendicular to the transparent base material side, wherein Q wherein U is the mean value of the transmission intensity determined by extrapolation of a straight line connecting the transmission intensity in the direction +2 degrees from the direction of regular transmission with the transmission intensity in the direction +1 degree from the direction of regular transmission, and a straight line connecting the transmission intensity in the direction −2 degrees from the direction of regular transmission with the transmission intensity in the direction −1 degree from the direction of regular transmission, to regular transmission respectively.
