Abstract
A method for transferring a micro device on a curved surface according to an exemplary embodiment of the present invention includes: coating an adhesive layer on an external circumferential surface of a tube; providing a micro device pattern on one side of a substrate; positioning an external circumferential surface of the tube to contact the substrate and allow a length direction of the device pattern to cross a radius direction of the tube, and rotating the tube with respect to an axis-direction of the tube and simultaneously moving at least one of the tube and the substrate in a rectilinear way to transfer the micro device pattern on the substrate to the adhesive layer; and fixing the transferred micro device pattern to the adhesive layer by curing the adhesive layer.
