Abstract
The present invention relates to an optical film including a light-transmitting substrate film such as a polyester-based substrate film and an antiglare layer, and more specifically, to an optical film capable of effectively suppressing the occurrence of interference fringes derived from the substrate film, realizing excellent antiglare properties, and having excellent scratch resistance, and excellent adhesion between the substrate film and the antiglare layer, and the like, and to an image display device including the same.
