ORGANIC LIGHT EMITTING DISPLAY DEVICE AND REPAIR METHOD THEREOF
First Claim
1. An organic light emitting display device comprising:
- a substrate;
two or more first electrodes positioned on the substrate and spaced apart from one another;
an auxiliary electrode positioned between the first electrodes;
a barrier rib positioned on the auxiliary electrode and having a reversely tapered structure including at least two layers;
a bank layer exposing portions of the first electrodes to define a light emission region;
an organic layer positioned in the light emission region and patterned by the barrier rib; and
a second electrode positioned on the organic layer and the barrier rib, and disposed to be in contact with the auxiliary electrode.

16. A method for repairing an organic light emitting display device including a substrate, a plurality of first electrodes positioned on the substrate and spaced apart from one another, an auxiliary electrode positioned between the first electrodes, a barrier rib positioned on the auxiliary electrode and having a reversely tapered structure including at least two layers, a bank layer exposing portions of the first electrodes to define a light emission region, an organic layer positioned in the light emission region and patterned by the barrier rib, and a second electrode positioned on the organic layer, spaced apart from the barrier rib, and disposed to be in contact with the auxiliary electrode, the method comprising:
-
irradiating a laser to the barrier rib to melt portions of the barrier rib and the second electrode positioned on the barrier rib; and forming the second electrode such that the second electrode continues from an upper surface of the organic layer to an upper surface of the barrier rib. - View Dependent Claims (17, 18, 19, 20)
