Abstract

An object is to provide a light-emitting device having a structure in which an external connection portion can easily be connected and a method for manufacturing the light-emitting device. A light-emitting device includes a lower support 110 , a base insulating film 112 over the lower support 110 which has a through-hole 130 , a light-emitting element 127 over the base insulating film 112 , and an upper support 122 over the light-emitting element 127 . An electrode 131 is provided in the through-hole 130 , and the external connection terminal 132 electrically connected to the electrode 131 is provided below the base insulating film 112 . The external connection terminal 132 is electrically connected to the external connection portion 133 and functions as a terminal that inputs a signal or a power supply into the light-emitting device. This light-emitting device has a structure in which an external connection portion can easily be connected.

First claim

What is claimed is:

a first flexible support;
an element formation layer over the first flexible support with a first adhesive layer interposed therebetween, the element formation layer comprising a transistor, a first insulating film, a light-emitting element, and a second insulating film;
an electrode configured to be electrically connected to an external connection portion; and
a second flexible support over the element formation layer with a second adhesive layer interposed therebetween,
wherein the second insulating film is over the first insulating film,
wherein the first insulating film comprises a first opening portion,
wherein the electrode is provided in the first opening portion,
wherein the electrode does not overlap the second insulating film,
wherein the second insulating film comprises a second opening portion, and
wherein the light-emitting element is provided in the second opening portion.

2. The light-emitting device according to claim 1 , wherein the electrode overlaps the second adhesive layer.

3. The light-emitting device according to claim 1 , wherein the electrode does not overlap the first adhesive layer.

4. The light-emitting device according to claim 1 , wherein the electrode is in contact with the second adhesive layer.
