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.
