Mask and method of manufacturing display device by using the same
A mask includes: a frame; and a mask base attached to the frame, having an opening such that light is illuminated, and including a first surface and a second surface that is opposite to the first surface, and the mask base has a welding portion at an outer portion of the mask base and a half-etching portion in at least a portion of the first surface and/or the second surface of the mask base.
1. A method of manufacturing a display device, the method comprising:
forming a display portion on a substrate;
preparing a first mask comprising:
a frame; and
a mask base comprising:
a first surface;
a second surface; and
a half-etching portion in a portion of the first surface or the second surface, wherein the half-etching portion continuously extends along each side at an outer portion of the mask base;
forming an organic layer using the first mask;
preparing a second mask for an inorganic layer; and
forming the inorganic layer to cover the organic layer using the second mask,
wherein the half-etching portion is at a corner of the mask base, and
wherein the half-etching portion is inside a welding portion.
2. The method of claim 1 , wherein the preparing of the first mask comprises:
forming the half-etching portion in the mask base; and
welding the mask base to the frame.
3. The method of claim 1 , wherein the display portion comprises an organic light-emitting device.
4. The method of claim 1 , wherein the half-etching portion at least partially surrounds a center portion of the mask base.
5. The method of claim 1 , wherein the mask base comprises the welding portion that extends along each side of an outer portion of the mask base.
6. The method of claim 1 , wherein the mask base comprises the welding portion that continuously extends along each side of an outer portion of the mask base.
7. A mask comprising:
a frame; and
a mask base attached to the frame and defining an opening through which light may be illuminated, the mask base comprising:
a first surface;
a second surface opposite to the first surface;
a welding portion at an outer portion of the mask base; and
a half-etching portion at a portion of at least one of the first surface and the second surface,
wherein the half-etching portion continuously extends along each side at an outer portion of the mask base,
wherein the half-etching portion is at a corner of the mask base, and
wherein the half-etching portion is inside the welding portion.
8. The mask of claim 1 , wherein the half-etching portion is between the opening and the welding portion.
9. The mask of claim 1 , wherein the half-etching portion is in a pattern across an entire surface of the mask base.
10. The mask of claim 1 , wherein the mask is configured to be used for curing an organic thin film encapsulation layer with ultraviolet light.
11. The mask of claim 1 , wherein the half-etching portion at least partially surrounds a center portion of the mask base.
12. The mask of claim 1 , wherein the welding portion extends along each side of the outer portion of the mask base.
13. The mask of claim 1 , wherein the welding portion continuously extends along each side of the outer portion of the mask base.
