Abstract

This invention relates to a mask for an organic electro-luminescence device and a method of fabricating the same that is capable of forming an organic layer having a special color without a damage of an organic layer formed on a substrate. The mask for the organic electro-luminescence device includes: an open part formed in a hole type to pass an organic material for forming a first organic layer on a substrate; and a blocking part having a groove on a surface facing to at least one second organic layer formed on the substrate, wherein the groove has a width corresponding to a width of the second organic layer.

Claims (5)

1. A mask for an organic electro-luminescence device comprising:

an open part formed in a hole type to pass an organic material for forming a first organic layer on a substrate; and

a blocking part having a groove on a surface facing to at least one second organic layer formed on the substrate, wherein the groove has a width corresponding to a width of the second organic layer.

2. The mask according to claim 1 , wherein at least one groove is formed to correspond to at least one of second organic layers.

3. The mask according to claim 1 , wherein one groove is formed with a width corresponding to a whole width of at least two of second organic layers formed on the substrate.
