An optical film in which a function of a brightness enhancement film is maintained and variations in brightness and chromaticity within a film plane are suppressed is provided. An optical film is a laminate of an absorptive dichroic polarizing plate and a brightness enhancement film. A maximum chromaticity difference Δxy(max) of in-plane transmitted light is 0.008 or smaller after the optical film is attached to a glass plate and allowed to stand at 70° C. for 120 hours. The brightness enhancement film includes a layer having a circularly polarized light separating function, and a quarter wavelength plate. The quarter wavelength plate is a film showing an in-plane retardation (Δnd) satisfying Δnd(450 nm)/Δnd(550 nm)

A cable end structure in which the cable end device and an intermediate cushion are tightly engaged with each other by mating conical surfaces without an apprehension that they might be shifted relatively to each other. In this way, inflection of the cushion and interfacial contact pressure caused by such inflection can be minimized and the durability of the cushion can be effectively improved.
