摘要： A method of evaluating an image blur of an optical film includes displaying a test pattern by driving an organic light-emitting display apparatus including the optical film, obtaining an image by capturing the test pattern using a digital camera, obtaining a spatial luminance distribution from the image, transforming the spatial luminance distribution into a sensation curve, and estimating a blur width from the sensation curve, where the blur width is a distance between peaks having negative minimum values, from among a plurality of peaks of the sensation curve.
