Abstract

A display apparatus is provided. In the display apparatus, a plurality of light emitting devices are mounted in an orderly arranged state, mending light emitting devices capable of light emission are disposed directly above the failed ones of the plurality of light emitting devices, whereby the portions of the failed ones of the plurality of light emitting devices can be mended (repaired), and it is possible to eliminate dark spot defects in use of the display apparatus.

Claims (21)

1. A display apparatus comprising:

a plurality of light emitting devices mounted in an orderly arranged state, at least one of said plurality of light emitted devices being a failed light emitting device and including a first light emitting layer; and

a mending light emitting device including a second light emitting layer and capable of emitting light disposed directly above one of the failed light emitting devices;

wherein the second light emitting layer is disposed above the first light emitting layer.

2. The display apparatus as set forth in claim 1 , wherein a mending wiring communicated with a wiring connected to said failed light emitting device is connected to said mending light emitting device.

3. The display apparatus as set forth in claim 1 , wherein said mending light emitting device has the same structure as that of said plurality of light emitting devices mounted in the orderly arranged state.

4. The display apparatus as set forth in claim 1 , wherein said display apparatus is a display.

5. The display apparatus as set forth in claim 1 , wherein said display apparatus is a liquid crystal backlight.

6. The display apparatus as set forth in claim 1 , wherein said display apparatus is of a top emission type.

7. The display apparatus as set forth in claim 1 , wherein said light emitting device is a light emitting diode.

8. A method of manufacturing a display apparatus including a plurality of light emitting devices mounted in an orderly arranged state, said method comprising:

embedding a mending light emitting device including a first light emitting layer and capable of emitting light in an insulation film covering said plurality of light emitting devices, at a position directly above a failed one of said plurality of light emitting devices, the failed one of said plurality of light emitting devices including a second light emitting layer disposed below the first light emitting layer;

providing said insulation film with contact holes communicated respectively with said mending light emitting device and a wiring connected to said failed light emitting device; and

forming mending wirings for connecting said mending light emitting device and said wiring connected to said failed light emitting device to each other through said contact holes.

9. The method of manufacturing the display apparatus as set forth in claim 8 , comprising:

breaking at least a part of said wiring connected to said failed light emitting device, before carrying out said step of embedding said mending light emitting device.

10. The method of manufacturing the display apparatus as set forth in claim 8 , wherein a light emitting device having the same structure as that of said plurality of light emitting devices mounted in the orderly arranged state is used as said mending light emitting device.

11. The method of manufacturing the display apparatus as set forth in claim 8 , wherein said display apparatus is a display.

12. The method of manufacturing the display apparatus as set forth in claim 8 , wherein said display apparatus is a liquid crystal backlight.

13. The method of manufacturing the display apparatus as set forth in claim 8 , wherein said display apparatus is of a top emission type.

14. The method of manufacturing the display apparatus as set forth in claim 8 , wherein a light emitting diode is used as said light emitting device.
