Display unit and method of manufacturing the same
View Patent ↗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.
1. A display unit, comprising:
a drive panel including a plurality of light-emitting devices on a drive substrate with a drive device layer and a coating layer being laid over the drive device layer in between;
a sealing panel including a sealing substrate that faces the drive panel on a side where the light-emitting devices are disposed; and
a middle layer being disposed between the drive panel and the sealing panel so as to be laid over the plurality of light-emitting devices, and being laid over a surface and an end surface of the coating layer, wherein the middle layer includes an adhesive layer for bonding the whole surfaces of the drive panel and the sealing panel together.
2. The display unit according to claim 1 , wherein
the coating layer includes an organic material.
3. The display unit according to claim 1 , wherein
a peripheral circuit portion is disposed in a peripheral portion of the drive substrate, and the casting layer is formed on the peripheral circuit portion.
4. The display unit according to claim 1 , wherein
the middle layer includes a protective film that is provided on the plurality of light-emitting devices and the surface and the end surface of the coating layer; and an adhesive layer that is disposed between the protective film and the sealing substrate so as to bond a whole surface of the drive panel and the protective film, and a whole surface of the sealing panel together.
5. The display unit according to claim 1 , wherein
the coating layer includes a first portion protruded from an end surface of the middle layer, and the protruded portion and a second portion of the coating layer are separated by a separating groove.
6. The 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.
7. The display unit according to claim 6 , wherein
the light-emitting devices include an auxiliary electrode for preventing a voltage drop in the second electrode, and the auxiliary electrode is in contact with the coating layer.
8. A display unit, comprising:
a drive panel including a plurality of light-emitting devices on a drive substrate with a drive device layer and a coating layer being laid over the drive device layer in between;
a sealing panel including a sealing substrate that faces the drive panel on a side where the light-emitting devices are disposed;
a middle layer being disposed between the drive panel and the sealing panel so as to be laid over the plurality of light-emitting devices, and being laid over a surface and an end surface of the coating layer, wherein the middle layer includes a protective film that is provided on the plurality of light-emitting devices and the surface and the end surface of the coating layer; and
an adhesive layer that is disposed between the protective film and the sealing substrate so as to bond a whole surface of the drive panel and the protective film, and a whole surface of the sealing panel together.
