Abstract: A quantum dot (“QD”) glass aging device including a bottom part including a flat surface defined by a first direction and a second direction intersecting the first direction; a side wall part including a side surface defined by the first direction and a third direction intersecting the bottom part, and a seating part disposed between the bottom part and the side wall part. The seating part includes a plurality of protrusion parts extending in the first direction and arranged in the second direction. A plurality of QD glasses is arranged on the plurality of protrusion parts. A plurality of light sources is disposed in the plurality of grooves defined between the protrusion parts and between the side wall part and a first protrusion part adjacent to the side wall part. Heights of upper surfaces of the protrusion parts gradually decrease from the side wall part to the bottom part.
