Light-emitting device, lighting device, and electronic device

摘要

It is an object to provide a flexible light-emitting device with high reliability in a simple way. Further, it is an object to provide an electronic device or a lighting device each mounted with the light-emitting device. A light-emitting device with high reliability can be obtained with the use of a light-emitting device having the following structure: an element portion including a light-emitting element is interposed between a substrate having flexibility and a light-transmitting property with respect to visible light and a metal substrate; and insulating layers provided over and under the element portion are in contact with each other in the outer periphery of the element portion to seal the element portion. Further, by mounting an electronic device or a lighting device with a light-emitting device having such a structure, an electronic device or a lighting device with high reliability can be obtained.

主权项

1. A light-emitting device comprising:
a substrate having flexibility and a light-transmitting property with respect to visible light; a first insulating layer over the substrate; an element portion over the first insulating layer, wherein the element portion comprises a light-emitting element and a switching element for applying a potential to the light-emitting element; a second insulating layer covering a side surface and a top surface of the element portion; a sealing material over the second insulating layer, wherein the sealing material surrounds an outer periphery of the element portion; and a metal substrate overlapping with the light-emitting element, wherein the first insulating layer and the second insulating layer are in direct contact with each other in a region which is in the outer periphery of the element portion and is surrounded by the sealing material, wherein the switching element comprises a semiconductor layer, and wherein the semiconductor layer is totally over the first insulating layer.
