Abstract
A display device is provided which includes a lower substrate and an upper substrate. An inner surface of the lower substrate and an inner surface of the upper surface face each other. A polarizing plate is disposed on an outer surface of the upper substrate, wherein the polarizing plate includes at least an inside protective film, a polarizing film and an outside protective film, which are layered on the upper substrate side in this order so that the inside protective film is adjacent to the upper substrate. An expansion axis of the outside protective film forms an angle of 30° or more and 90° or less with an expansion axis of the polarizing film, and an expansion axis of the inside protective film forms an angle of 0° or more and 3° or less with an expansion axis of the polarizing film.
