Organic electroluminescence display and method for manufacturing the same

An organic EL device, comprising:

• a substrate having a first electrode arranged on an active region;
• at least one organic material layer formed on the first electrode;
• a second electrode formed on the organic material layer;
• a seal-cup facing the second electrode while being connected with the second electrode via a sealant;
• and
• a heat conductor connecting an edge of the second electrode inside a seal line with the seal-cup to dissipate heat of the device to an outside thereof.

A method for manufacturing an organic EL device, comprising the steps of:

• forming a substrate having a first electrode formed thereon;
• forming at least one organic material layer on the first electrode such that holes and electrons are injected to the organic material layer, and then combined therein to emit light therethrough;
• forming a second electrode on the organic material layer to extend outside of a seal line;
• forming a seal-cup to face the second electrode;
• and
• applying a sealant to the second electrode on the seal line and to an edge of the seal-cup, followed by curing the sealant to seal the organic EL device.

A method for manufacturing an organic EL device, comprising the steps of:

• forming a substrate having a first electrode formed thereon;
• forming a heat conductive layer on the substrate outside an active region of the substrate;
• forming at least one organic material layer on the first electrode such that holes and electrons are injected to the organic material layer, and then combined therein to emit light therethrough;
• forming a second electrode on the organic material layer within the active region;
• connecting the heat conductive layer outside the active region with the second electrode within the active region;
• and
• forming a seal-cup to face the second electrode, followed by connecting an edge of the seal-cup with the second electrode at a seal line using a sealant to seal the organic EL device.
