A method of manufacturing a display device includes forming on a first substrate a display element and a metal layer surrounding the display element, the metal layer including a first portion having a first width and a second portion having a second width less than the first width, forming on a second substrate a sealing member surrounding the display element, the sealing member including a first sealing portion having a first forming width and a second sealing portion having a second forming width greater than the first forming width, arranging the first substrate and the second substrate such that the sealing member on the second substrate faces the first substrate, the first sealing portion overlaps the first portion of the metal layer, and the second sealing portion overlaps the second portion of the metal layer, and sealing the first and second substrates by melting and curing the sealing member.
