Abstract: Disclosed is a method of manufacturing a multicolor quantum dot pattern, which includes: forming a first photoresist pattern on a substrate; activating a surface of the substrate having the first photoresist pattern formed thereon; forming a first quantum dot layer on the activated substrate; generating a first quantum dot pattern by removing the first photoresist pattern; and generating a second quantum dot pattern on the same layer as the first quantum dot pattern generated on the substrate. Accordingly, various kinds of quantum dots may be easily implemented at a single substrate.
