Abstract

A flat panel display apparatus includes: a first substrate, a second substrate opposite the first substrate and including a display region in which a plurality of pixels are formed, and a sealing member between the first substrate and the second substrate; the sealing member bonds the first substrate and the second substrate to each other. The sealing member overlaps at least a part of outermost pixels of the display region.

Claims (33)

1. A flat panel display apparatus, comprising:

a first substrate;

a second substrate opposite the first substrate, the second substrate including a display region in which a plurality of pixels are formed; and

a sealing member between the first substrate and the second substrate, the sealing member bonding the first substrate and the second substrate to each other,

wherein the sealing member partially overlaps and directly contacts outermost pixels of the display region.

2. The flat panel display apparatus as claimed in claim 1 , wherein:

the second substrate includes at least one driving unit that supplies a plurality of driving signals to the plurality of pixels,

wherein the sealing member overlaps at least one driving unit.

3. The flat panel display apparatus as claimed in claim 2 , wherein the sealing member further comprises:

a first sealing member formed on the first substrate and partially overlapping and directly contacting the outermost pixels of the display region; and

a second sealing member disposed between the first substrate and the second substrate and formed on outer sides of the at least one driving unit.

4. The flat panel display apparatus as claimed in claim 1 , wherein the plurality of pixels includes organic light emitting diodes (OLEDs).

5. The flat panel display apparatus as claimed in claim 4 , wherein the sealing member partially overlaps a light emitting layer of the OLEDs of outermost pixels of the display region.

6. The flat panel display apparatus as claimed in claim 1 , wherein an area where the sealing member partially overlaps the outermost pixels of the display region is determined such that visibility of the outermost pixels of the display region is the same as that of inner pixels of the display region.

7. The flat panel display apparatus as claimed in claim 1 , wherein the sealing member surrounds outer sides of the display region.

8. The flat panel display apparatus as claimed in claim 1 , wherein the sealing member is a frit.

9. A method of manufacturing a flat panel display apparatus that includes a first substrate, a second substrate opposite the first substrate, and a display region in which a plurality of pixels are formed, the method comprising:

forming a sealing member on the first substrate, the sealing member being located on the first substrate to partially overlap outermost pixels of the display region when the first substrate is disposed on the second substrate;

disposing the first substrate on the second substrate such that the sealing member partially overlaps and directly contacts the outermost pixels of the display region; and

bonding the first substrate to the second substrate by using the sealing member.

10. The method as claimed in claim 9 , wherein:

the second substrate includes at least one driving unit that supplies a plurality of driving signals to the plurality of pixels,

wherein forming the sealing member includes locating the sealing member on the first substrate such that the sealing member overlaps the at least one driving unit when the first substrate is disposed on the second substrate.

11. The method as claimed in claim 10 , wherein forming the sealing member includes:

forming a first sealing member on the first substrate to partially overlap with outermost pixels of the display region when the first substrate is disposed on the second substrate; and

forming a second sealing member on the first sealing member and to be disposed on outer sides of the at least one driving unit when the first substrate is disposed on the second substrate.

12. The method as claimed in claim 10 , wherein bonding the first substrate to the second substrate includes melting and hardening the sealing member by irradiating a laser beam or infrared light onto at least a part of outer sides of the at least one driving unit.

13. The method as claimed in claim 9 , wherein the plurality of pixels include organic light emitting diodes (OLEDs).

14. The method as claimed in claim 13 , wherein forming the sealing member includes locating the sealing member on the first substrate such that the sealing member partially overlaps a light emitting layer of the OLEDs of the outermost pixels of the display region when the first substrate is disposed on the second substrate.

15. The method as claimed in claim 9 , wherein an area where the sealing member and the outermost pixels of the display region partially overlap is determined such that visibility of the outermost pixels of the display region is the same as that of inner pixels of the display region.

16. The method as claimed in claim 9 , wherein forming the sealing member includes forming the sealing member to surround outer sides of the display region.

17. The method as claimed in claim 9 , wherein bonding the first substrate to the second substrate includes melting and hardening the sealing member by irradiating a laser beam or infrared light onto at least a region of the sealing member.

18. The method as claimed in claim 9 , wherein the sealing member is a frit.
