A display device according to an exemplary embodiment of the present disclosure can include a back cover, a display panel disposed on the back cover, a polarizing plate disposed on the display panel, a barrier film disposed on the polarizing plate, and a side film which has one end disposed between the back cover and the display panel and another end disposed between the polarizing plate and the barrier film to enclose side surfaces of the display panel and the polarizing plate. Therefore, the moisture permeation into the polarization layer is delayed, which in turn improves the reliability of the display device.
