1. A method of forming a light-emitting element by growing a separation layer and a light-emitting layer in this order on a first substrate, bonding the light-emitting layer onto a second substrate, and removing the separation layer to form the light-emitting layer on the second substrate, comprising:
growing a plurality of groups of the separation layers and the light-emitting layers on the first substrate, wherein the separation layer and the light-emitting layer to be grown on the first substrate constitute one group;
patterning the light-emitting layer existing as a uppermost layer into an island shape, and then bonding the light-emitting layer to the second substrate; and
etching the separation layer adjacent to the light-emitting layer patterned into the island shape to form the light-emitting layer patterned into the island shape on the second substrate.
