1. A display device comprising:
a thin film transistor substrate comprising a thin film transistor;
light emitting elements on the thin film transistor substrate and comprising a first light emitting element and a second light emitting element;
a pixel electrode connected to one end of the thin film transistor and electrically connected to one end of the first or the second light emitting elements via a first contact electrode;
a common electrode on the thin film transistor substrate and electrically connected to an other end of one of the first or second light emitting elements via a second contact electrode;
a pixel defining layer including an opening at least partially exposing the one of the first or second light emitting elements;
an insulator on the one of the first or second light emitting elements in the opening of the pixel defining layer;
a color conversion layer comprising a red color conversion layer on the first light emitting element and a green color conversion layer on the second light emitting element, the red color conversion layer comprising a plurality of quantum dot materials, and the green color conversion layer comprising a plurality of quantum dot materials; and
a light blocking layer on the red and green color conversion layers,
wherein the color conversion layer is directly on the insulator,
wherein the first and second contact electrodes contact a bottom surface of the one of the first or second light emitting elements facing away from the color conversion layer, and
wherein the insulator contacts a top surface and the bottom surface of the one of the first or second light emitting elements.
