Mask for deposition, method of manufacturing mask, and method of manufacturing display device

A method of manufacturing a display device by using a mask for deposition, the method comprising:

• inserting a display substrate and the mask for deposition into a chamber;
• and
• depositing a deposition material over the display substrate, the deposition material being sprayed from a deposition source and passing through the mask for deposition,
• wherein the mask for deposition includes:
• a first rib having a first thickness;
• and
• a pattern portion including:
• a plurality of pattern holes, and
• at least one etch portion, the at least one etch portion having a second thickness that is less than the first thickness and connecting between some of the plurality of pattern holes, and
• wherein some of the plurality of pattern holes are disposed in a rhombus shape.
