  • Antiglare light diffusing member
    Publication number: 20080112055
    Abstract: An antiglare light diffusing member is provided comprising a transparent base material and an antiglare light diffusing layer including a binder matrix, a particle A and a particle B. A front surface of the antiglare light diffusing layer should not be flat. The difference between a refractive index of the particle 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 particle B and a refractive index of the binder matrix can be 0.03-0.2. An average particle diameter of the particle A can be bigger than an average film thickness of the antiglare light diffusing layer. An average particle diameter of the particle B is smaller than an average film thickness of the antiglare light diffusing layer.
