Abstract

A mask frame assembly includes a mask having pattern openings and a frame including a first support portion configured to support an end of the mask and having a clamping slot and a support slot adjacent to the clamping slot; and a second support portion connected to the first support portion.

Claims

1. A mask frame assembly comprising:

a mask having pattern openings; and

a frame comprising;

a first support portion having a clamping slot and a support slot, the support slot being adjacent to the clamping slot; and

a second support portion connected to the first support portion.

2. The mask frame assembly of claim 1, wherein the mask comprises a first welding opening extending through an end of the mask.

3. The mask frame assembly of claim 2, further comprising a first welding portion at the first welding opening and connecting the mask and the first support portion to each other.

4. The mask frame assembly of claim 1, wherein the clamping slot extends through the first support portion.

5. The mask frame assembly of claim 1, wherein the clamping slot has a depth that is less than a thickness of the first support portion.

6. The mask frame assembly of claim 1, wherein the support slot extends along a second direction.

7. The mask frame assembly of claim 1, further comprising a support stick extending along a second direction, accommodated in the support slot, and being over the clamping slot.

8. The mask frame assembly of claim 7, wherein the support stick comprises a second welding opening extending through an end of the support stick.

9. The mask frame assembly of claim 8, further comprising a second welding portion at the second welding opening and joining the support stick to at least one of the first support portion and the second support portion.

10. The mask frame assembly of claim 1, wherein the first support portion further comprises a cutting slot arranged nearer to a center of the frame assembly than the support slot is.

11. The mask frame assembly of claim 10, wherein the mask is nearer to a center of the frame assembly than an outer end of the cutting slot is.

12. A method of manufacturing a mask frame assembly, the method comprising:

arranging a mask on a frame, the mask having pattern openings and the frame comprising;

a first support portion configured to support an end of the mask and having a clamping slot and a support slot, the clamping slot being configured to allow in and out movement of a clamper, and the support slot being adjacent to the clamping slot; and

a second support portion connected to the first support portion;

mounting a support stick on the support slot and over the clamping slot, the support stick extending along a second direction;

stretching an end of the mask in a first direction crossing the second direction and aligning a portion of the end of the mask to be on the support stick;

joining the mask and the frame to each other; and

removing a cutting portion of the mask.

13. The method of manufacturing the mask frame assembly of claim 12, further comprising preparing the mask by forming a first welding opening extending through an end of the mask.

14. The method of manufacturing the mask frame assembly of claim 13, wherein the joining the mask and the frame comprises forming a first welding portion at the first welding opening to join the mask and the frame to each other.

15. The method of manufacturing the mask frame assembly of claim 12, wherein the clamping slot has a depth that is less than a thickness of the first support portion.

16. The method of manufacturing the mask frame assembly of claim 12, wherein the clamping slot extends through the first support portion.

17. The method of manufacturing the mask frame assembly of claim 12, wherein the support slot extends along the second direction.

18. The method of manufacturing the mask frame assembly of claim 12, wherein the mounting the support stick on the support slot comprises forming a second welding opening that extends through an end of the support stick and forming a second welding portion at the second welding opening to join the support stick and the frame to each other.

19. The method of manufacturing the mask frame assembly of claim 12, further comprising preparing the mask, the preparing the mask comprising forming a cutting slot on the first support portion, the cutting slot being arranged nearer to a center of the mask frame assembly than the support slot is, having a depth that is less than a thickness of the first support portion, and both the ends of the mask being arranged nearer to the center of the mask frame assembly than an outside surface of the cutting slot after the cutting portion of the mask is removed.

20. A method of manufacturing a display device, the display device comprising a first electrode and a second electrode oppositely facing each other on a substrate and an organic layer between the first electrode and the second electrode, wherein the organic layer and the second electrode are deposited on the substrate by using a mask frame assembly, the mask frame assembly comprising:

a mask having pattern openings; and

a frame, the frame comprising;

a first support portion configured to support an end of the mask and having a clamping slot and a support slot adjacent to the clamping slot; and

a second support portion connected to the first support portion.
