Abstract
An optical film constituted by a laminate of a polarizer and a reflective polarizing film through an acrylic-based pressure-sensitive adhesive agent, the polarizer having an anti-glare layer, wherein the optical film has a haze (H) in a range of from 5% to 30%. Preferably, a haze (H1) of the polarizer and a haze (H2) of the reflective polarizing film satisfy the relation H1>H2. Preferably, the haze (H) of the optical film satisfies the relation H/H1>0.5.
