Abstract
Provided is a light reflecting plate capable of reducing glare of reflected light while maintaining high light reflectance by regular reflection. The light reflecting plate includes a base, a light reflecting layer that is formed on the base and made of silver or silver alloy, or aluminum or aluminum alloy, in which arithmetic average roughness (Ra) is 0.10 to 0.30 μm and arithmetic average waviness (Wa) is 0.30 to 2.50 μm on a surface of the light reflecting layer.
