Organic electro luminescence device and fabrication method thereof

A fabrication method of an organic electro luminescence device, the fabrication method comprising:

• forming an array element including a TFT (thin film transistor) corresponding to a sub pixel on the first substrate;
• forming a first electrode corresponding to the sub pixel on a second substrate;
• forming a separator on the first electrode so as to separate the sub pixel into a first region and a second region;
• forming an organic electro luminescent layer on the first electrode of one of the first and second regions;
• forming a second electrode on the organic electro luminescent layer;
• electrically connecting the array element of the first substrate and the first electrode of the second substrate;
• and
• attaching the first substrate to the second substrate,
• wherein forming the organic electro luminescent layer comprises:
• placing a mask on the second substrate, the mask having a transmitting part and a blocking part;
• and
• depositing an organic electro luminescent material on a first portion of the second substrate through the transmitting part of the mask,
• wherein an insulating bank prior to depositing the organic electro luminescent material on the second substrate, and depositing the organic electro luminescent material such that the organic electro luminescent material contacts an edge of the bank.
