Abstract
The present invention relates to a substrate for color conversion, a manufacturing method therefor, and a display device comprising the same and, more specifically, to a substrate for color conversion for not only securing the long-term stability of quantum dots but also exhibiting excellent color conversion efficiency, a manufacturing method therefor, and a display device comprising the same. To this end, the present invention provides a substrate for color conversion, a manufacturing method therefor, and a display device, the substrate for color conversion comprising: a thin plate glass; a coating layer for quantum dots formed on one surface of the thin plate glass; a light guide plate disposed to face the coating layer for quantum dots, a light emitting diode being disposed on the sides thereof; and a sealing material which is formed between the thin plate glass and the light guide plate and which blocks the coating layer for quantum dots from the outside.
