1. A method for manufacturing a display panel, the method comprising:
providing a mask assembly on a target substrate; and
providing a light-emitting pattern of the display panel on the target substrate through the mask assembly,
wherein the mask assembly comprises:
a mask frame in which a first opening is defined extended through a front surface of the mask frame; and
a deposition mask which is attached to the front surface of the mask frame and through which a second opening is defined corresponding to the light-emitting pattern of the display panel,
wherein
the mask frame includes an attachment orientation in which the front surface extends along a direction of gravity,
the deposition mask includes an initial mask which is attached to the front surface of the mask frame in the attachment orientation thereof and through which the second opening is defined, and
the attachment orientation of the mask frame having the front surface which extends along the direction of gravity disposes the first opening of the mask frame corresponding to the second opening of the initial mask along the direction of gravity.
