PROBLEM TO BE SOLVED: To provide a light transmission plate which has such fluidity as to be molded at a relatively low temperature, has excellent moisture absorption characteristics and therefore has suppressed warpage or deformation of the product at a high temperature and high humidity, and also has high light resistance. SOLUTION: The light transmission plate is obtained by molding a thermoplastic resin comprising 5 to 40 pts. wt. of unsaturated carboxylic acid monomers, 60 to 95 wt.% of aromatic vinyl monomers and having 50,000 to 150,000 molecular weight with 2.0 to 3.0 molecular weight distribution.
