COMBINATION TYPE OPTICAL FILM, LAMINATED COMBINATION TYPE OPTICAL FILM AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a combination type optical film which includes a plurality of optical films, the end faces of which are butted against one another and which can prevent light leakage without degrading appearance.SOLUTION: In the combination optical film including a plurality of optical films, at least the one end face of which are butted against one another, the butted end faces are bonded to one another with a bonding agent having substantially the same refractive index as that of the optical films.
