Light emitting device

摘要

It is an object of the present invention to provide a light-emitting device where periphery deterioration can be prevented from occurring even when an organic insulating film is used as an insulating film for the light-emitting device. In addition, it is an object of the present invention to provide a light-emitting device where reliability for a long period of time can be improved. A structure of an inorganic film, an organic film, and an inorganic film is not continuously provided from under a sealing material under a cathode for a light-emitting element. In addition, penetration of water is suppressed by defining the shape of the inorganic film that is formed over the organic film even when a structure of an inorganic film, an organic film, and an inorganic film is continuously provided under a cathode for a light-emitting element.

主权项

1. A light-emitting device comprising:
a first substrate; a first conductive film over the first substrate; a first insulating film over the first conductive film; a second conductive film over the first insulating film; a second insulating film over the second conductive film; a light-emitting film over the second conductive film; a third conductive film over the light-emitting film; and a second substrate opposed to the first substrate with a sealing material interposed therebetween, wherein the sealing material and the first conductive film overlap each other, wherein the sealing material and the third conductive film do not overlap each other, wherein the first conductive film comprises a plurality of openings being in contact with the sealing material, each of the plurality of openings having a narrower-side direction and a wider-side direction, and wherein the wider-side direction of each of the plurality of openings is a direction extended from the light-emitting film to a side of the sealing material in contact with each of the plurality of openings.
