PROBLEM TO BE SOLVED: To provide a transmission type display material, which has an improved white light transmittance and effectively diffuses the light so that the element of a light source cannot be clearly seen. SOLUTION: An image formation element is formed by involving a transparent polymer sheet, at least one layer of biaxial oriented polyolefin sheet, and at lease one layer of image layer. The polymer sheet has a rigidity of 20-100 mN. The biaxial oriented polyolefin sheet has a spectral transmittance of at least 40%, and a reflection density of less than 600%, desirably 46-54%. |
