Light-emitting device
View Patent ↗A light-emitting device includes a substrate on which a laminate is disposed, a sealing substrate bonded to the substrate with a plurality of seals therebetween, a plurality of mounting sites in regions surrounded by the seals on the sealing substrate, and a plurality of adsorbers disposed in the mounting sites to adsorb water and oxygen. The laminate includes a first electrode, a second electrode, and an electrooptical material therebetween. The electrooptical material at least includes a light-emitting layer. The seals have the shape of a double or multiple frame surrounding the periphery of the laminate on the substrate.
1. A light-emitting device comprising:
a substrate on which a laminate is disposed, the laminate including a first electrode, a second electrode, and an electrooptical material therebetween, the electrooptical material at least including a light-emitting layer;
a sealing substrate bonded to the substrate with a plurality of seals therebetween, the seals having the shape of a double or multiple frame surrounding the periphery of the laminate on the substrate, wherein the plurality of seals include:
a first seal surrounding the periphery of the laminate on the substrate; and
a second seal surrounding the periphery of the first seal;
a plurality of mounting sites in regions surrounded by the seals on the sealing substrate, wherein the plurality of mounting sites include:
a first mounting site in a region surrounded by the first seal on the sealing substrate; and
a second mounting site in a region surrounded by the first seal and the second seal on the sealing substrate, the first and second mounting sites each having a recess, wherein:
the first seal is disposed on a first support formed of a protrusion around the recess in the first mounting site; and
the second seal is disposed on a second support formed of a protrusion around the recess in the second mounting site;
a plurality of adsorbers disposed in the mounting sites to adsorb water and oxygen, wherein the plurality of adsorbers include:
a first adsorber in the first mounting site; and
a second adsorber in the second mounting site;
a seal opening formed by partially joining the first and second supports together;
a first discontinuous portion where the frame shape of the first seal on the first support is interrupted at the seal opening; and
a second discontinuous portion where the frame shape of the second seal on the second support is interrupted at the seal opening;
wherein the first discontinuous portion extends outward to the second discontinuous portion; and
the seal opening is sealed by a plurality of opening-sealing members.
2. The light-emitting device according to claim 1 , wherein the plurality of seals have a rectangular shape in plan view.
3. The light-emitting device according to claim 1 , wherein the first and second adsorbers have different adsorption capabilities.
4. The light-emitting device according to claim 3 , wherein the first adsorber adsorbs a larger amount of water and oxygen than the second adsorber.
5. The light-emitting device according to claim 3 , wherein the second adsorber adsorbs water and oxygen at a higher rate than the first adsorber.
6. The light-emitting device according to claim 1 , wherein the plurality of opening-sealing members are integrated.
7. The light-emitting device according to claim 1 , wherein no adsorber is disposed at a position on the sealing substrate opposite the laminate on the substrate.
