1. A display device comprising:
a display panel comprising pixels configured to receive a driving signal;
a polarizing plate comprising a polarizer disposed on an entire surface of the display panel;
an adhesive film disposed between the polarizing plate and the display panel;
a first protective film disposed directly on a first side of the polarizer;
a second protective film disposed directly on a second side of the polarizer, the second side opposing the first side;
a surface treatment film disposed on the first side of the polarizer; and
a barrier film disposed directly on the surface treatment film,
wherein:
the polarizer comprises at least one transmission region overlapping at least some of the pixels and polarization regions excluding the at least one transmission region;
the at least one transmission region has a same thickness as the polarization regions;
the at least one transmission region and the polarization regions include a same material;
the at least one transmission region of the polarizer at least partially overlaps with a display region of each pixel among the at least some of the pixels;
the display region is configured to display a portion of an image according to the driving signal;
the polarizer is disposed between the first protective film and the adhesive film;
the barrier film is disposed directly on the first protective film such that the barrier film is disposed between the surface treatment film and the first side of the polarizer;
the surface treatment film comprises at least one of a hard coating layer, an anti-adhesion layer, an anti-diffusion layer, and an anti-glare layer; and
the adhesive film directly contacts the second protective film and the display panel.
