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 rollably display device includes a flexible display panel with an active area for displaying images and a non-active area surrounding the active area. A first seal member is disposed in the non-active area on a first portion of a side surface of the display panel and a second seal member is disposed on the first seal member and on a second portion of the side surface of the display panel to reduce the likelihood of occurrence of cracks at the sides of the display panel during rolling and unrolling of the display panel around a roller.
