Abstract: 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.

Abstract: A display device and a method for manufacturing the same are disclosed, in which excitation and side permeability of a flexible substrate are minimized to prevent defects of a display panel from occurring. The display device comprises a first substrate; a buffer layer arranged on the first substrate; a pixel array layer arranged on the buffer layer; and an encapsulation layer covering the pixel array layer, wherein the buffer layer surrounds a front surface and a side of the first substrate. The method for manufacturing a display device comprises the steps of preparing a supporting substrate; forming a plurality of first substrates spaced apart from one another on the supporting substrate; forming a buffer layer covering the plurality of first substrates; forming a pixel array layer on an area of the buffer layer overlapped with each of the plurality of first substrates; forming an encapsulation layer covering the pixel array layer; and forming a plurality of display panels by cutting the supporting substrate and the buffer layer based on cutting lines defined among the plurality of first substrates.

Abstract: A flexible, rollable display system includes a display and one or more cover components coupled thereto. The cover components include openings that, when the display is wound around a roller, reduce induced stresses and the likelihood of the display cracking. The roller may include a flat portion to accommodate a printed circuit board or other electronic components less flexible than the display. The cover component(s) may be formed of heat radiating material(s) to improve performance of the system.
