Laser-induced thermal imaging apparatus, method of laser-induced thermal imaging, and manufacturing method of organic light-emitting display apparatus using the method

A method of manufacturing an organic light-emitting display apparatus, comprising the steps of:

• transferring a substrate including an active area onto a substrate support unit;
• positioning a donor film on the substrate;
• irradiating a linear laser beam onto the donor film after the linear laser beam passes through a second mask, including a transmission unit corresponding to the active area of the substrate and a blocking unit outside the transmission unit, after passing through a first mask including a plurality of openings arranged along a length direction of the linear laser beam and passing through an optical system interposed between the first mask and the second mask;
• and
• transferring a transfer layer of the donor film onto the substrate in a linear pattern extended in one direction that is not perpendicular to the length direction of the linear laser beam by scanning the substrate by the linear laser beam in the one direction.
