The present invention provides a transparent plastic sheet comprising: a support layer including a polycarbonate resin layer; and a polymethylmethacrylate resin layer, which is formed as a surface layer on the support layer and has a glass transition temperature of 120-135°C, wherein the thickness of the polymethylmethacrylate resin layer is 5-20% of the total thickness of the sheet, and the overall transmittance of the sheet is 89-94% based on ASTM D1003. Therefore, the deformation of the transparent plastic sheet can be minimized under high-temperature and high-humidity conditions, and thus the transparent plastic sheet can be favorably applied, as a window cover for glass replacement, to various display products. |
