Abstract:
1. A mask for crystallizing a semiconductor layer, the mask comprising: a plurality of first main-slit portions extending along an inclined direction with respect to a first direction, the first main-slit portions being disposed substantially parallel to one another and along a second direction substantially perpendicular to the first direction; a plurality of second main-slit portions being spaced apart from the first main-slit portions in the first direction, the second main-slit portions extending along the inclined direction with the same length as the first main-slit portions and disposed substantially parallel to one another and along the second direction; at least one upper slit portion disposed substantially parallel to and above the first main-slit portions along the second direction, the upper slit portions extending toward the second main-slit portions to be longer than the first main-slit portions; and at least one lower slit portion disposed substantially parallel to and under the second main-slit portions along the second direction, the lower slit portions extending toward the first main-slit portions to be longer than the second main-slit portions.
