Abstract

An organic electroluminescence device includes a first substrate, a first electrode layer formed over the first substrate, an organic light emitting layer formed over the first substrate, a second electrode layer formed over the organic light emitting layer, a second substrate, a seal pattern on an outer portion of the first substrate or the second substrate for forming a cell gap between the two substrates and for attaching the two substrates, and a plurality of cell gap maintaining structures located between the first substrate and the second substrate.

Claims (27)

1. A method for fabricating an organic electroluminescence device comprising:

forming a first electrode layer on an upper part of a first substrate;

forming an organic light emitting layer on an upper part of the first electrode layer;

forming a second electrode layer on an upper of the organic light emitting layer;

applying an organic material on the first substrate having the second electrode layer;

providing a second substrate;

forming cell gap maintaining structure between the first substrate and the second substrate by patterning the organic material;

forming a plurality of recesses by etching the second substrate;

installing desiccant film in the recesses;

forming a seal pattern on an outer portion of the substrate or the second substrate; and

attaching the first substrate and the second substrate using the seal pattern.

2. The method of claim 1 , further comprising forming a passivation layer on an upper part of the second electrode layer before applying an organic material.

3. The method of claim 1 , wherein the cell gap maintaining structure is formed on the first substrate.

4. The method of claim 1 , wherein the cell gap maintaining structure is formed on the second substrate.

5. A method for fabricating an organic electroluminescence device comprising:

forming a first electrode layer on an upper part of a first substrate;

forming an organic light emitting layer on an upper part of the first electrode layer;

forming a second electrode layer on an upper of the organic light emitting layer; forming a passivation layer on an upper part of a second substrate;

applying an organic material on the passivation layer;

forming cell gap maintaining structure between the first substrate and the second substrate by patterning the organic material;

forming a seal pattern on an outer portion of the first substrate or the second substrate;

attaching the first substrate and the second substrate using the seal pattern.

6. The method of claim 5 , wherein the cell gap maintaining structure is formed on the first substrate.

7. The method of claim 5 , wherein the cell gap maintaining structure is formed on the second substrate.

8. The method of claim 5 , further comprising:

forming a plurality of recesses by etching the second substrate; and

installing desiccant film in the recesses.
