Abstract
The present disclosure relates to the field of quantum dot display technology and discloses a method for manufacturing a quantum dot display device. The method comprises: providing an array substrate and a counter substrate opposite to each other; printing an alignment solution containing a quantum dot material onto a side of the array substrate facing the counter substrate; removing a solvent in the alignment solution printed onto the side of the array substrate facing the counter substrate; heating the array substrate after removal of the solvent; and providing a backlight source at a side of the array substrate facing away from the counter substrate. The present disclosure further relates to a corresponding quantum dot display device. With such a manufacturing method, the display quality of the resulting quantum dot display device is greatly improved, and the associated manufacturing cost and process difficulty are reduced.
