Plastic sheet

A plastic sheet having a thickness of from 1 to 5 mm, a haze of 80% or more and a total light transmittance of 80% or more, which comprises at least one diffuser layer A, two or more diffuser layers B, and optionally a diffusing agent-free layer C,

• the diffuser layer A comprising 100 parts by weight of a first matrix plastic and from 0.2 to 1.5 parts by weight of a first light-diffusing fine particle having an average particle size of from 2 to 6 μm and a refractive index of from X−0.02 to X+0.02 wherein X is a refractive index of the first matrix plastic;
• the diffuser layer B comprising 100 parts by weight of a second matrix plastic and from 10 to 30 parts by weight of a second light-diffusing fine particle having an average particle size of from 10 to 18 μm and a refractive index of from Y−0.03 to Y+0.03 wherein Y is a refractive index of the second matrix plastic, and
• two adjacent diffuser layers B being separated by an intervening diffuser layer A or diffusing agent-free layer C.
