An image display screen which is composed of a multi-layer film consisting of at least 11 layers and formed by alternately laminating first thermoplastic resin layers having a thickness of 0.05 to 0.03 m with second thermoplastic resin layers having a thickness of 0.05 to 0.3 m and a parallel ray transmittance of 50% or more, and which has at least a reflection peak with a maximum reflectance 5 to 80% higher than the base line of reflectance and a half-value width of 20 to 200 nm in its reflectance curve for visible light having a wavelength of 380 to 780 nm, and an image display device comprising the same as a screen. This screen has improved transparency while maintaining the definition of an image.
