Organic electroluminescence display device and method for fabricating the same

A method for fabricating an organic electroluminescence display device, comprising the steps of:

• preparing a device substrate and an encapsulating substrate;
• forming a semiconductor layer, a gate insulating layer, a gate electrode, a scan line and an interlayer dielectric layer;
• forming a contact hole for exposing a part of the semiconductor layer by etching a prescribed region of the interlayer dielectric layer;
• forming source/drain electrode materials on the device substrate;
• forming source/drain electrodes, a data line, a first lower power supply line and a second lower power supply line by patterning the source/drain electrode materials;
• forming an insulating layer on the device substrate;
• forming a first electrode on the insulating layer;
• forming a pixel defining layer and forming a first via-hole and a second via-hole for exposing the first lower power supply line and the second lower power supply line, respectively, by patterning the pixel defining layer material after forming a pixel defining layer material the surface of the device substrate;
• forming an organic layer including at least an organic light emitting layer, and a second electrode on the device substrate;
• forming a moisture absorbing material on the encapsulating substrate;
• forming a second upper power supply line and a first upper power supply line at respective positions on the encapsulating substrate corresponding to the first lower power supply line and the second lower power supply line;
• forming a first contact member and a second contact member in the first via-hole and the second via-hole, respectively;
• and
• sealing the device substrate by the encapsulating substrate in such a manner that the first lower power supply line and the first upper power supply line contacted to each other via the first contact member, the second lower power supply line and the second upper power supply line are contacted to each other via the second contact member.
