Abstract

Light-emitting devices are formed on a support substrate, whereas a black matrix is provided on a transparent opposed substrate. The support substrate and the opposed substrate are adhered to each other in the condition where the display devices are sealed with an adhesive resin and the adhesive resin is charged between the support substrate and the opposed substrate. In this case, alignment of the support substrate and the opposed substrate is conducted so that the surface of the opposed substrate provided with the black matrix is faced to the surface of the support substrate provided with the light-emitting devices and the black matrix is disposed faced to the spaces between the light-emitting devices. The alignment is conducted by disposing alignment marks provided on the surface of the support substrate provided with the light-emitting devices and alignment marks provided on the opposed substrate into a predetermined condition.

Claims

1. A display unit comprising:

a support substrate provided with light-emitting devices and inter-device wiring in a display region;

a transparent opposed substrate provided with a black matrix and disposed on the side of the surface forming the light-emitting device of said support substrate, said black matrix forming a pattern to cover at least said inter-device wiring; and

a sealing adhesive resin charged and filling the space between said support substrate and said opposed substrate in the condition of sealing said light-emitting devices.

2. A display unit as set forth in claim 1, wherein said opposed substrate is provided in the condition where the surface forming the black matrix thereof is faced to said support substrate.

3. A display unit as set forth in claim 2, wherein an anti-reflection film is provided on the surface of said opposed substrate on the side opposite to the surface forming the black matrix.

4. A display unit as set forth in claim 1, wherein said black matrix is comprised of a laminate film having a predetermined reflected-light-attenuation structure or resin material film.

5. A display unit as set forth in claim 1, further comprising alignment marks used for aligning said light-emitting devices on said support substrate and said black matrix on said opposed substrate into a predetermined condition, said alignment marks being provided on the surface forming the light-emitting device of said support substrate and on said opposed substrate, and being located outside of the display region.

6. A display unit as set forth in claim 1, wherein said sealing adhesive resin acquires transparency when cured.

7. A method of manufacturing a display unit comprising the steps of:

providing light-emitting devices and inter-device wiring in a display region on a support substrate,

providing a black matrix on a transparent opposed substrate, said black matrix forming a pattern to cover at least said inter-device wiring, and

adhering said support substrate and said opposed substrate in the condition where said light-emitting devices are sealed with an adhesive resin and said adhesive resin is charged and fills the space between said support substrate and said opposed substrate.

8. A method of manufacturing a display unit as set forth in claim 7, wherein said support substrate and said opposed substrate are adhered in the condition where the surface forming the black matrix of said opposed substrate is faced to the surface forming the light-emitting device of said support substrate.

9. A method of manufacturing a display unit as set forth in claim 7, wherein said support substrate and said opposed substrate are aligned into a predetermined condition using alignment marks so that said black matrix is disposed to cover at least said inter-device wiring in the step of adhering said support substrate and said transparent opposed substrate.

10. A method of manufacturing a display unit as set forth in claim 9, wherein said alignment marks are provided on the surface forming the light-emitting device of said support substrate and on said opposed substrate, said alignment marks being located outside of the display region.

11. A method of manufacturing a display unit as set forth in claim 9, wherein said alignment of said support substrate and said opposed substrate is conducted in the condition where said support substrate and said opposed substrate are adhered to each other through said adhesive resin before said adhesive resin is cured, and thereafter said adhesive resin is cured.

12. A method of manufacturing a display unit comprising the steps of disposing an opposed substrate on the side of a display region provided on a support substrate, and adhering said support substrate and said opposed substrate through an adhesive resin, wherein alignment of said support substrate and said opposed substrate is conducted in the condition where said support substrate and said opposed substrate are adhered to each other through said adhesive resin and before said adhesive resin is cured, and thereafter said adhesive resin is cured.

13. A method of manufacturing a display unit as set forth in claim 12, wherein light-emitting devices are formed in said display region, and said adhesive resin is charged and fills the space between said support substrate and said opposed substrate in the condition of sealing said light-emitting devices.

14. A method of manufacturing a display unit comprising the steps of disposing an opposed substrate faced to a surface of a support substrate on which light-emitting devices are formed, and adhering said support substrate and said opposed substrate in the condition where said light-emitting devices are sealed with an adhesive resin and said adhesive resin is charged and fills the space between said support substrate and said opposed substrate, wherein alignment of said support substrate and said opposed substrate is conducted so that alignment marks provided on said support substrate and alignment marks provided on said opposed substrate are disposed in a predetermined condition in the step of adhering said support substrate and said opposed substrate, said alignment marks being located outside of the display region.
