  • DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME
    Publication number: 20240067849
    Abstract: A display device includes a display panel including a first surface and a second surface opposite to the first surface, a polarizing member disposed on the first surface of the display panel, a window member disposed on the polarizing member, and a first adhesive member disposed between the window member and the polarizing member and including an ultraviolet light absorber. A side surface of the display panel, a side surface of the polarizing member, and a side surface of the first adhesive member have a first surface roughness, an upper surface of the first adhesive member has a second surface roughness less than the first surface roughness, and the side surface of the display panel, the side surface of the polarizing member, and the side surface of the first adhesive member are aligned at a boundary.
