Disclosed herein is a transfer printing technology. A transfer printing substrate includes a plurality of pillar structures and a sacrificial layer applied thereon. In situ alignment of a transfer layer is performed by the pillar structures and a structural confinement by a concave structure formed on a bottom surface of the transfer layer corresponding to the pillar structures, or a chemical bond of the pillar structure and the transfer layer. In the in situ alignment by the structural confinement, the remaining sacrificial layer after being removed may serve as an adhesive component. The transfer process is performed by a separation of the bond by the sacrificial layer, a cutting of the pillar structures in the chemic bonding state of the pillar structures and the transfer layer, or a separation of the bond between the pillar structures and the handling substrate.
