  • Publication number: 20090262429
    Abstract: The purpose is to provide an antiglare light diffusing member that can satisfy both of external light reflection preventiveness and good contrast when being used for a display. The antiglare light diffusing member is made to be an antiglare light diffusing member having an antiglare light diffusing layer including a binder matrix and particles on a transparent base material, wherein the two types of surface roughness (Ra1, Ra2) of the antiglare light diffusing layer defined by JIS-B0601-1994 are in the following range: Ra1: in the range of 0.008-0.020 ?m Ra2: less than 0.200 ?m (Ra1: cutoff wavelength ?c of 0.008 mm, Ra2: cutoff wavelength ?c of 0.8 mm).

  • Patent number: 7525731
    Abstract: An antiglare light diffusing member is provided comprising a transparent base material and an antiglare light diffusing layer including a binder matrix, a plurality of particles (A) and a plurality of particles (B). A front surface of the antiglare light diffusing layer should not be flat. The difference between a refractive index of the plurality of particles (A) and a refractive index of the binder matrix can be less than or equal to 0.02. The difference between a refractive index of the plurality of particles (B) and a refractive index of the binder matrix can be 0.03-0.2. An average particle diameter of the plurality of particles (A) can be bigger than an average film thickness of the antiglare light diffusing layer. An average particle diameter of the plurality of particles (B) is smaller than an average film thickness of the antiglare light diffusing layer.
