Summary:PROBLEM TO BE SOLVED: To provide an inexpensive scratch resistance lens sheet capable of preventing a scratch of a lens structure surface, making the scratch inconspicuous when being scratched, and furthermore, preventing occurrence of moire to attain high quality of an obtained image.SOLUTION: In a scratch resistance lens sheet, many lens structure 2 are arranged in parallel on one surface of the scratch resistance lens sheet, many projections 3 having a spot shape are irregularly formed to be higher than a lens apex by 5-100 μm and to have substantially uniform height. The projections 3 are arranged across adjacent lens structure, and ratio of total installation area of the projections 3 with respect to total area of the lens sheet 1 is 0.3-20%.
