Abstract
The present invention relates to a laser pattern mask, and a method for fabricating the same, which can prevent a laser pattern mask from being damaged by coating a protective film on a surface of a laser pattern mask for patterning an entire layer on a mother substrate at a time by laser ablation. The laser pattern mask includes a base substrate, a laser shielding pattern formed of a non-transparent metal on the base substrate to define laser pass through regions, and a protective film formed on an entire surface of the base substrate including the laser shielding pattern.
