Title:
LIGHT EMITTING APPARATUS, LIGHT EMITTING MODULE, ELECTRONIC DEVICE, AND MANUFACTURING METHOD FOR LIGHT EMITTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/039293
Kind Code:
A1
Abstract:
Provided is a light emitting apparatus that can display images for a long period of time in a bent state. Also provided is a light emitting apparatus that can be repeatedly bent at a small curvature radius. This light emitting apparatus is flexible and has a light emitting element, a first inorganic insulating layer, a second inorganic insulating layer, and a first organic insulating layer. The first organic insulating layer is positioned on the first inorganic insulating layer. The light emitting element is positioned on the first inorganic insulating layer, with the first organic insulating layer sandwiched therebetween. The second inorganic insulating layer is positioned on the light emitting element. An edge of the first inorganic insulating layer and an edge of the second inorganic insulating layer are both positioned further to the inside than an edge of the first organic insulating layer. The edge of the first organic insulating layer is exposed at a side surface of the light emitting apparatus. It is preferable that the first inorganic insulating layer and the second inorganic insulating layer be in contact with each other outside of the edge of the light emitting element.
