Abstract

A display unit and method of manufacturing same is provided. The display unit includes a drive panel and a sealing panel that face each other with a middle layer in between. The display panel includes a number of light-emitting devices on a drive substrate with a drive device layer and a coating layer that is provided over the drive device layer in between. The middle layer is disposed between the drive panel and the sealing panel so as to be laid over the light-emitting devices.

Claims

1. A method of manufacturing a display unit, comprising:

forming a plurality of light-emitting devices on a drive substrate with a drive device layer and a coating layer that is formed on the drive device layer in between to form a drive panel;

forming a middle layer being laid over the plurality of light-emitting devices and a surface and an end surface of the coating layer; and

disposing a sealing panel including a sealing substrate on a side of the drive panel where the light-emitting devices are disposed so as to face the drive panel with the middle layer in between, wherein the middle layer includes an adhesive layer for bonding the whole surfaces of the drive panel and the sealing panel together.

2. The method of manufacturing a display unit according to claim 1, wherein the coating layer is formed by disposing a sheet-shaped coating film.

3. The method of manufacturing a display unit according to claim 1, wherein subsequent to forming a photosensitive film that includes a photosensitive material, the photosensitive film is exposed and developed so as to form the coating layer.

4. The method of manufacturing a display unit according to claim 1, wherein similar to the middle layer, a protective film being laid over the plurality of light-emitting devices and the end surface of the coating layer, and an adhesive layer are formed in order, then the whole surfaces of the drive panel and the protective film and the whole surface of the sealing panel are bonded together with an adhesive layer in between.

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

the light-emitting devices are organic light-emitting devices each having a laminate including a first electrode, an organic layer including a light-emitting layer, and a second electrode in order from the drive substrate so as to extract light generated in the light-emitting layer from the second electrode.
