Abstract
Official abstract text for this publication.
The present invention includes a frame-shaped sealing material, a filling layer, and a support. The frame-shaped sealing material is provided between a TFT substrate and a counter substrate, and is configured to seal an organic EL element (electroluminescent element) along with the TFT substrate and the counter substrate. The filling layer is composed of a liquid filler, and is filled in the space between the counter substrate, a sealing film, and the sealing material. The support is located inside the sealing material and between the TFT substrate and the counter substrate, and also supports the TFT substrate and the counter substrate.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electroluminescent device comprising: a substrate; an electroluminescent element provided on the substrate; a counter substrate that is located opposite the substrate; a sealing film that seals the electroluminescent element; a frame-shaped sealing material that is provided between the substrate and the counter substrate, and that is configured to seal the electroluminescent element along with the substrate and the counter substrate; and a filling layer that is composed of a liquid filler, and that is filled in a space between the counter substrate, the sealing film, and the frame-shaped sealing material, and wherein a support is located inside the sealing material and between the substrate and the counter substrate so as to leave holes through which the filler can flow, and also supports the substrate and the counter substrate. 2. The electroluminescent device according to claim 1 , wherein the support includes a plurality of support members that are arranged parallel to a side of the frame-shaped sealing material. 3. The electroluminescent device according to claim 1 , wherein the support includes a plurality of support members that are arranged perpendicular to a side of the frame-shaped sealing material. 4. The electroluminescent device according to claim 1 , wherein the support includes a plurality of support members that are arranged only along long sides of four sides of the frame-shaped sealing material. 5. The electroluminescent device according to claim 1 , wherein the support is configured such that a size of a support member located in an end portion of a side of the framed-shaped sealing material is larger than that of a support member located in a central portion of the side of the frame-shaped sealing material. 6. The electroluminescent device according to claim 1 , wherein the support includes a plurality of support members that are alternately arranged along a side of the frame-shaped sealing material. 7. The electroluminescent device according to claim 1 , wherein the electroluminescent element includes a first electrode provided on the substrate and a second electrode provided on the counter substrate, the second electrode is a reflecting electrode and light from the electroluminescent element is emitted from the substrate to the outside. 8. The electroluminescent device according to claim 1 , wherein the support is made of the same material as that of the sealing material.
