Abstract: Disclosed, in the present specification, is a transfer substrate for transferring a semiconductor light emitting device with high reliability and a method for manufacturing a display device by using same. Specifically, the transfer substrate includes an organic stamp layer having a protrusion, wherein the organic stamp layer contains a plurality of inorganic fillers, and the concentration of the inorganic fillers is formed so as to increase as the distance from the protrusion increases. Therefore, the protrusion of the organic stamp layer has a low concentration of the inorganic fillers so as to maintain sufficient adhesion for transferring the semiconductor light emitting device, and the stiffness of the organic stamp layer itself is formed so as to be much stronger than that of a stamp layer using a single organic material. Accordingly, it is possible to improve the accuracy of transfer by minimizing an arrangement error of the semiconductor light emitting device due to the deformation of the stamp layer occurring in a transfer process. Accordingly, it is possible to improve the accuracy of transfer by minimizing an arrangement error of the semiconductor light emitting device caused by the deformation of the stamp layer occurring during a transfer process.
