PROBLEM TO BE SOLVED: To execute accurate quantitative evaluation of dazzle in mounting an antidazzle film on a high-precision image display device. SOLUTION: The purpose is accomplished by providing this dazzle evaluation device for an antidazzle film characterized by comprising: a lattice pattern formed on a luminescent surface of a light source; the antidazzle film mounted on the lattice pattern; a photographing means for photographing light from the light source through the lattice pattern and the antidazzle film; and an image data processing means for computing Fourier transform of image data obtained by photographing the light by the photographing means, and thereafter outputting it as a spectrum formed by removing a bright line corresponding to the lattice pattern or by applying a predetermined process to the spectrum.
