Display device and method of manufacturing the same

A display device comprising:

• a transistor disposed on a base layer, the transistor comprising:
• an active layer;
• a gate electrode;
• a first transistor electrode electrically connected to a first contact region of the active layer;
• and
• a second transistor electrode electrically connected to a second contact region of the active layer;
• an interlayer insulating layer disposed on the gate electrode;
• a bank disposed on the interlayer insulating layer and protruding in a thickness direction of the base layer;
• a color conversion layer disposed between a first portion of the bank and a second portion of the bank so as to overlap the first and second portions of the bank in a direction perpendicular to the thickness direction of the base layer, the color conversion layer including quantum dots that change a color of light;
• and
• a light emitting element disposed on the color conversion layer,
• wherein a reflective electrode layer is disposed on the first and second portions of the bank so as to surround the color conversion layer in the direction perpendicular to the thickness direction of the base layer.
