Abstract

A method of manufacturing a display not needing a complicated post-process for forming a reflecting mirror film and allowing degradation in an organic light-emitting device to be prevented, and a display. The method of manufacturing a display includes the steps of: forming a plurality of organic light-emitting devices in a display region on a substrate to form a light-emitting panel; forming projection-shaped reflection elements corresponding to the plurality of organic light-emitting devices, respectively, on a base to form a reflector; forming an adhesive layer along an outer edge of the light-emitting panel; and bonding the light-emitting panel and the reflector together with the adhesive layer in a vacuum atmosphere, thereby to form a vacuum layer in a space between the light-emitting panel and the reflector.

Claims (20)

1. A method of manufacturing a display comprising:

forming a plurality of organic light-emitting devices in a display region on a substrate to form a light-emitting panel;

forming projection-shaped reflection elements corresponding to the plurality of organic light-emitting devices, respectively, on a base to form a reflector, wherein for each reflection element a color filter is formed between the base and the light output side of the reflection element, wherein the reflection elements are separated from one another in a plan view on a light output side of the reflection element by a distance greater than widths of light blocking members that are alternately arranged with the reflection elements;

forming an adhesive layer along an outer edge of the substrate of the light-emitting panel; and

bonding the light-emitting panel and the reflector together with the adhesive layer in a vacuum atmosphere such that the adhesive layer, the substrate of the light-emitting panel, and the base of the reflector encase the organic light-emitting devices and the reflection elements, thereby to form a vacuum layer in a space between the light-emitting panel, the adhesive layer, and the reflector, wherein a thickness of the adhesive layer corresponds to a thickness of the vacuum layer.

2. The method of manufacturing a display according to claim 1 , wherein

in the step of forming the adhesive layer, a getter is arranged outside of the display region of the light-emitting panel, and then the adhesive layer is formed outside of the getter.

3. The method of manufacturing a display according to claim 1 , wherein a fixing layer is formed between the reflector elements and the light-emitting panel.

4. A display comprising:

a light-emitting panel including a plurality of organic light-emitting devices in a display region on a substrate;

a reflector including projection-shaped reflection elements corresponding to the plurality of organic light-emitting devices, respectively on a base, wherein for each reflection element a color filter is formed between the base and the light output side of the reflection element, wherein the reflection elements are separated from one another in a plan view on a light output side of the reflection element by a distance greater than widths of light blocking members that are alternately arranged with the reflection elements;

an adhesive layer formed along an outer edge of the substrate of the light-emitting panel so as to bond the light-emitting panel and the reflector together such that the adhesive layer, the substrate of the light-emitting panel, and the base of the reflector encase the organic light-emitting devices and the reflection elements; and

a vacuum layer formed in a space between the light-emitting panel, the adhesive layer, and the reflector, wherein a thickness of the adhesive layer corresponds to a thickness of the vacuum layer.

5. The display according to claim 4 , wherein

in the reflector, light emitted from the plurality of organic light-emitting devices is reflected by an interface between a side surface of each of the reflection elements and the vacuum layer.

6. The display according to claim 4 , wherein

a getter is arranged between the display region of the light-emitting panel and the adhesive layer.

7. The display according to claim 4 , wherein

a getter is arranged between the display region of the light-emitting panel and the adhesive layer.

8. The display according to claim 4 , wherein a fixing layer is formed between the reflector elements and the light-emitting panel.
