Abstract: The present invention is applicable to display device-related technical fields and may provide a transfer substrate in which multiple semiconductor light-emitting elements of a first color and a light conversion layer formed on at least a portion of the semiconductor light-emitting elements to convert the first color into a second color or a third color are formed, the transfer substrate comprising: multiple unit pixels including one light-emitting element among the multiple semiconductor light-emitting elements; and a pixel including at least one of the multiple unit pixels, wherein the pixel includes a first pixel and a second pixel adjacent to each other and the light conversion layer of the unit pixel disposed at a position adjacent to the first pixel and the second pixel includes a light-emitting element which converts the first color into the same color.
