Display apparatus and method of manufacturing the same
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.
1. A display apparatus comprising:
a first substrate;
a display arranged on the first substrate and comprising a light-emitting diode;
a second substrate facing the first substrate;
a first sealed area arranged between the first substrate and the second substrate, surrounding the display, and comprising a frit; and
a second sealed area arranged in the first sealed area and comprising at least one portion protruding toward the first substrate and/or the second substrate, the at least one portion comprising an area in which materials of the frit and the first substrate, and/or materials of the frit and the second substrate are melted and mixed with each other.
2. The display apparatus of claim 1 , wherein the first substrate and/or the second substrate comprises a glass material.
3. The display apparatus of claim 1 , wherein the first sealed area has a closed loop shape surrounding a periphery of the display.
4. The display apparatus of claim 1 , wherein
the first sealed area comprises a first end arranged proximate the display, and a second end arranged far from the display, and
a center of the second sealed area is nearer to the first end than to the second end.
5. The display apparatus of claim 4 , wherein the center of the second sealed area is between a point corresponding to ¼ of a width of the first sealed area from the first end and a point corresponding to ½ of the width of the first sealed area from the first end.
6. The display apparatus of claim 1 , wherein a width of the second sealed area is less than a width of the first sealed area.
7. The display apparatus of claim 1 , wherein the second sealed area is formed continuously in the first sealed area.
8. The display apparatus of claim 1 , wherein the second sealed area is formed discontinuously in the first sealed area.
9. The display apparatus of claim 1 , wherein the at least one portion comprises first and second portions respectively protruding toward the first substrate and the second substrate and respectively comprising the area in which the materials of the frit and the first substrate and the materials of the frit and the second substrate are melted and mixed with each other.
10. The display apparatus of claim 1 , wherein the at least one portion protruding toward the first substrate and/or the second substrate has a curved shape.
11. The display apparatus of claim 1 , further comprising a metal layer between the second sealed area and the first substrate.
12. The display apparatus of claim 4 , wherein the first sealed area is bonded to the first substrate and the second substrate from the first end to the second end.
