Display device

A method of manufacturing a display device, the method comprising:

• disposing first, second, third and fourth driving transistors on a substrate;
• disposing an intermediary layer on the first, second, third and fourth driving transistors;
• disposing first, second, third and fourth light emitting diodes on the intermediary layer, the first, second, third and fourth light emitting diodes being connected to the first, second, third and fourth driving transistors, respectively;
• testing the first, second, third and fourth light emitting diodes to determine whether any defective light emitting diode exists among the first, second, third and fourth light emitting diodes;
• disposing color conversion members over non-defective light emitting diodes among the first, second, third and fourth light emitting diodes, respectively;
• and
• disposing a black matrix to completely cover a remaining light emitting diode among the first, second, third and fourth light emitting diodes that does not include the non-defective light emitting diodes.
