UNIT MASK STRIP AND METHOD FOR PRODUCING ORGANIC LIGHT-EMITTING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a unit mask strip with a reduced positioning error of an opening pattern and a method for producing an organic light-emitting device using the same.SOLUTION: The unit mask strip 110 according to an embodiment of the present invention is a unit mask strip 110 fixed on a frame 140 pulled to a longitudinal direction with a plurality of unit masking pattern portions 120 in which opening patterns 122 are arranged in a matrix form having plurality of rows parallel to a crosswise direction orthogonal to the longitudinal direction and a plurality of columns parallel to the longitudinal direction. Each row of the opening patterns has a curvature and is formed by recessing to inside of the unit masking pattern portion 120 and each column of the opening patterns has a curvature and is formed inflating to outside of the unit masking pattern portion 120.
