Abstract: Provided is a method for a light conversion member including forming a plurality of grooves etched by a predetermined depth from a top surface to a bottom surface of a first substrate, forming a plurality of first connection members disposed in a first unit area partitioned by each of the grooves and having a closed loop shape surrounding each of the grooves on the top surface of the first substrate, forming a quantum dot member in the groove, forming a plurality of second connection members disposed in each of second unit areas partitioned on a bottom surface of a second substrate, cutting the second substrate along boundaries of the second unit areas; bonding a plurality of second sub substrates cut along the second unit areas to the top surface of the first substrate so as to overlap the first unit areas.
