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.

Abstract: Disclosed is a method of manufacturing a multicolor quantum dot pattern, the forming of a first quantum dot layer on the activated substrate includes: coating a polymer with a polarity opposite to a surface charge of the activated substrate or coating quantum dots having a functional group charged with a polarity opposite to a surface charge of the activated substrate onto the substrate; washing the substrate with water having pH 6 to pH 8; drying the substrate with flow of nitrogen, argon or air; coating quantum dots having a functional group charged with a polarity opposite to the polymer or the quantum dots charge coated on the substrate, or coating a polymer with a polarity opposite to the quantum dots charge coated on the substrate; washing the substrate with water having pH 6 to pH 8; and drying the substrate with flow of nitrogen, argon or air.
