Display device and method for manufacturing the same

A method for manufacturing a display device according to an embodiment of the present invention includes providing a display substrate and an encapsulation substrate, each of which has a display area and a non-display area surrounding the display area thereon, forming a nanowire on the encapsulation substrate overlapping a sealing area defined as a partial area of the non-display area, and combining the encapsulation substrate and the display substrate with each other, wherein the forming of the nanowire includes irradiating a first laser, which is a ultrashort pulse laser, onto the encapsulation substrate overlapping the sealing area, and the combining of the encapsulation substrate and the display substrate with each other includes irradiating a second laser, which is a ultrashort pulse laser, onto the display substrate overlapping the sealing area.
