MASK FRAME ASSEMBLY FOR THIN LAYER DEPOSITION AND METHOD OF MANUFACTURING ORGANIC LIGHT EMITTING DISPLAY DEVICE BY USING THE MASK FRAME ASSEMBLY
First Claim
1. A mask frame assembly for thin film deposition, comprising:
- a frame including an opening portion; and
a plurality of unit mask strips fixed to the frame after a tensile force is applied to both of end portions of the unit mask strips in a lengthwise direction of the unit mask strips;
each of the plurality of unit mask strips comprises a plurality of unit masking pattern portions each comprising a plurality of opening patterns; and
before the tensile force is applied to both of the end portions of the unit mask strips in the lengthwise direction and the unit mask strips are fixed to the frame, a width of each of the unit masking pattern portions in a widthwise direction perpendicular to the lengthwise direction increases as a function of a closeness of a portion of the unit masking pattern portion where the width is measured to a central portion of each of the unit masking pattern portions.

Abstract
A mask frame assembly for thin film deposition includes a frame including an opening portion, and a plurality of unit mask strips that are fixed to the frame after a tensile force is applied to both of end portions of the unit mask strips in a lengthwise direction of the unit mask strips. Each of the plurality of unit mask strips includes a plurality of unit masking pattern portions each including a plurality of opening patterns. Before the tensile force is applied to both of the end portions of the unit mask strips in the lengthwise direction and the unit mask strips are fixed to the frame, a width of each of the unit masking pattern portions in a widthwise direction perpendicular to the lengthwise direction increases as a function of a closeness of a portion of the unit masking pattern portion where the width is measured to a central portion of each of the unit masking pattern portions.

19. A method of manufacturing an organic light-emitting display device,
the organic light-emitting display device including an organic film disposed between a first electrode and a second electrode that are arranged opposite to each other on a substrate, the method comprising depositing the organic film through a mask frame assembly for thin film deposition, the mask frame assembly comprising: -
a frame including an opening portion; a plurality of unit mask strips having both of end portions in a lengthwise direction welded and fixed to the frame; each of the plurality of unit mask strips comprises a plurality of unit masking pattern portions each comprising a plurality of opening patterns; before a tensile force is applied to both of the end portions of the unit mask strips in the lengthwise direction and the unit mask strips are fixed to the frame, a distance between rightmost and leftmost opening patterns from among opening patterns existing on the same row in a widthwise direction perpendicular to the lengthwise direction increases as a function of a closeness of the row to a central portion of each of the unit masking pattern portions; and after a tensile force is applied to both of the end portions of the unit mask strips in the lengthwise direction and the unit masking pattern portions are fixed to the frame, the distance between rightmost and leftmost opening patterns from among opening patterns existing on the same row in the widthwise direction is substantially constant in a direction from both of the end portions of each of the unit masking pattern portions in the lengthwise direction toward the central portion of each of the unit masking pattern portions. - View Dependent Claims (20)
