Abstract:
A depolarizing film of the present invention comprises a film containing at least one liquid crystal compound, wherein the liquid crystal compound comprises a liquid crystal compound (1) that satisfies the relation: 0.05≦Δn≦0.5, with the proviso that Δn=ne−no, ne represents an extraordinary-ray refractive index, and no represents an ordinary-ray refractive index, and the film has a haze value of 15% or less and a thickness of 1 μm to 10 μm.
