Abstract
A highly durable polarizing plate and a display device including the same are provided. In the highly durable polarizing plate, sticking agent having different storage modulus are formed on top and bottom surfaces of a λ/4 retardation film. Such a highly durable polarizing plate can be attached to LCDs and OLEDs to realize high-quality screens due to a small change in retardation value under environments for reliability evaluation of heat resistance and wet-heat resistance.
