Fine metal mask and method of manufacturing the same
A method of manufacturing a fine metal mask is provided. The method of manufacturing a fine metal mask includes: forming a first recessed portion in a first surface of a base member; forming an edge portion of the first recessed portion in a uniform depth; forming a second recessed portion in a second surface of the base member, the second surface being opposite to the first surface; and communicating the first recessed portion and the second recessed portion of the base member. A fine metal mask produced by the inventive method is also described and may be used to fabricate OLEDs having better resolution and an increased aperture ratio in comparison with OLEDs prepared using the fine metal masks of the conventional art.
