Flat panel display including at least one substrate having a groove
A flat panel display and method of fabricating the same are disclosed. The flat panel display includes a first substrate having a pixel region; a light-emitting element located on the pixel region; a second substrate located opposite the first substrate; and a sealant located between the first and second substrates to cover the light-emitting element. At least one of the first and second substrates includes a groove formed around at least a portion of the circumference surrounding the pixel region. When the first and second substrates are pressed together with the sealant between them, the sealant spreads, covering the light-emitting element, and at least partially filling the groove.
1. A flat panel display comprising:
a first substrate having a pixel region, the pixel region defining a pixel region circumference;
a light-emitting element provided within the pixel region;
a second substrate opposite the first substrate;
a sealant between the first and second substrates and covering the light-emitting element, wherein at least one of the first and second substrates includes a groove corresponding to at least a portion of the pixel region circumference and facing the other of the first and second substrates; and
a moisture-absorbing layer between the sealant and the second substrate, wherein the moisture-absorbing layer comprises an alkaline earth metal oxide.
2. The flat panel display according to claim 1 , wherein the groove corresponds to the entire pixel region circumference.
3. The flat panel display according to claim 1 , wherein the groove has a depth between about 20 and about 500 μm.
4. The flat panel display according to claim 1 , wherein the groove has a width between about 0.1 and about 5 mm.
5. The flat panel display according to claim 1 , wherein the light-emitting element comprises a first electrode, an emission layer and a second electrode, which are sequentially stacked on the first substrate.
6. The flat panel display according to claim 5 , wherein the second electrode is a transparent electrode.
7. The flat panel display according to claim 1 , wherein the second substrate is a glass substrate or a plastic substrate.
8. The flat panel display according to claim 1 , wherein the sealant is a transparent sealant.
9. The flat panel display according to claim 1 , wherein the sealant is a thermosetting curing sealant or a UV light curing sealant.
10. The flat panel display according to claim 1 , wherein the alkaline earth metal oxide is calcium oxide or barium oxide.
11. A flat panel display comprising:
a first substrate having a pixel region, the pixel region defining a pixel region circumference;
a light-emitting element provided within the pixel region;
a second substrate opposite the first substrate; and
a sealant between the first and second substrates and covering the light-emitting element, the sealant comprising a moisture-absorbing material, wherein at least one of the first and second substrates includes a groove corresponding to at least a portion of the pixel region circumference and facing the other of the first and second substrates.
12. The flat panel display according to claim 11 , wherein the moisture-absorbing material comprises an alkaline earth metal oxide.
13. The flat panel display according to claim 12 , wherein the alkaline earth metal oxide is calcium oxide or barium oxide.
