Abstract
The display device includes a display panel including an active area and a non-active area; and a polarization plate on the display panel, the polarization plate including a polarization layer. The polarization layer includes a first pattern corresponding to the active area and a second pattern corresponding to the non-active area, and the second pattern is spaced apart from the first pattern. Thus, it is possible to delay moisture absorption of a polarization layer.
Claims21
A display device, comprising:
- a display panel including an active area and a non-active area;
- and
- a polarization plate on the display panel, the polarization plate including a polarization layer and protection layers respectively disposed on opposite surfaces of the polarization layer,
- wherein the polarization layer includes a first pattern corresponding to the active area and a second pattern corresponding to the non-active area,
- wherein the first pattern is continuous and planar across the first pattern and the second pattern is spaced apart from the first pattern, the second pattern being different from the first pattern,
- wherein the first pattern and the second pattern are spaced apart from each other by at least one of the protection layers, and
- wherein the polarization layer is a polyvinyl alcohol (PVA)-based polymer film.
