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.
