Abstract: A method of manufacturing a display apparatus includes: forming a plurality of displays including a light-emitting diode on a surface of a first mother substrate; preparing a second mother substrate; forming a first sealed area on a surface of at least one of the first mother substrate or the second mother substrate, wherein the first sealed area surrounds each of the plurality of displays and includes a frit; firstly bonding the first mother substrate to the second mother substrate by melting the frit in the first sealed area by radiating a first laser beam; and secondly bonding the first mother substrate to the second mother substrate by forming a second sealed area in which the frit and the first mother substrate, and/or the frit and the second mother substrate, are melted and mixed with each other by radiating a second laser beam partially in the first sealed area.
