Quantum dot (QD)/organic nanohybrids were developed to be utilized in electrohydrodynamic (EHD) jet‐printed QD‐LEDs. Side‐chain copolymer with elongated aliphatic thiol groups was newly introduced into the nanohybrids to coordinate the polymer chains with the QD surface. The QD‐LEDs with the nonohybrids showed a higher current efficiency over 4‐fold than that with a QD‐only active layer. EHD jet‐printing was independently performed up to 5µm pixel pitch on a substrate, resulting in a resolution of ca. 5,080 pixels per inch.
