Abstract:
An optical member comprising:a polarizing plate; a retarder plate; and a diffusing adhesive layer comprising a light-transmissible adhesive layer dispersively containing colorless light-transmissible particles so as to exhibit light diffusing characteristic, wherein a light diffusion factor of said diffusing adhesive layer is not higher than 10% in terms of the light diffusion factor which is defined as 100Ã—I30/I10, when I30 is intensity of light transmitted in a direction inclined by 30 degrees relative to a direction of perpendicular transmission of perpendicularly incident light, and I10 is intensity of light transmitted in a direction inclined by 10 degrees relative to the direction of perpendicular transmission of perpendicularly incident light, and said polarizing plate, said retarder plate, and said diffusing adhesive layer are laminated in this order, wherein the thickness of said diffusing adhesive layer is in a range of from 5 to 100 m.
