Abstract

An organic EL display device and a method for fabricating the same are disclosed, wherein an organic luminescence layer is formed at a crossing region of first and second electrodes using a shadow mask on which a plurality of holes are connected by bridges.

Claims (6)

1. A method for fabricating a display device comprising:

forming a first electrode pattern on a substrate;

forming at least one organic luminescence layer on the first electrode pattern at a plurality of pixels that is formed by aligning a mask having a plurality of holes and a plurality of bridges that connect the holes; and

forming a second electrode pattern on the organic luminescence layer in a perpendicular direction to the first electrode, wherein the bridges are formed on the same or different plane as the mask and thicker than the mask.

2. The method of claim 1 , wherein the mask is aligned three times so that each organic luminescence layer of R, G, and B is alternatively arranged in a row direction.

3. The method of claim 1 , wherein the substrate includes at least thin film transistors.
