PROBLEM TO BE SOLVED: To provide a light reflection plate having excellent light-reflecting property with excellent blue light cut-off property.SOLUTION: The light reflection plate comprises a thermoplastic resin and light-reflective fine particles, in which the total amount of metal elements of calcium, potassium and magnesium is 150 to 1000 μg/g, which results in excellent blue light cut-off property. While the reflection plate absorbs light in a blue color wavelength region where human eyes are likely adversely influenced, to suppress reflection of the light, the reflection plate can effectively reflect visible light in other wavelength regions and can give light that is harmless to human eyes as reflected light. |
