Provided is a mask for an evaporation apparatus, which includes a first division mask and a second division mask. The first and second division masks are directly bonded to each other by welding, thereby forming welding portion between the first and the second division masks. A method and apparatus for manufacturing a mask for evaporation are also provided. The division masks according to the embodiment do not use subframes, and are directly bonded to one another by welding, so that a shadow effect does not occur. The apparatus for manufacturing a mask for evaporation includes a work stage, a clamp fixing a first division mask and a second division mask to the work stage, and a laser welding part welding the first division mask to the second division mask. The apparatus may further include a first roller leading the laser welding part and a second roller following the laser welding part.

Mask for evaporation, and method and apparatus for manufacturing the same

A mask frame assembly using a plurality of stick-shaped split masks. The mask frame assembly includes a plurality of split masks, each of which includes a deposition pattern corresponding to a unit screen. Each of the split masks is formed of a plurality of partial masks to form the deposition pattern corresponding to a unit screen. Accordingly, the split masks accommodating a pattern corresponding to a large screen may be easily manufactured without an increase in the amount of etching errors.

Mask frame assembly for thin film deposition and the manufacturing method thereof

A mask frame assembly for thin film deposition, an organic light-emitting display device using the same, and a method of manufacturing the organic light-emitting display device. The organic light-emitting display device includes a first electrode and a second electrode patterned on a substrate to face each other, and a plurality of organic layers formed between the first and second electrodes. The plurality of organic layers include at least a plurality of stripe-shaped organic layers and a plurality of discontinuous dot-shaped organic layers.
