Quantum dot light-emitting diodes (QD-LEDs) were fabricated using multinary compound semiconductor QDs. The electroluminescence (EL) spectra of the RGB QD-LEDs indicated a significantly high color purity of 88% when compared to the BT.2020 standard. A passive-matrix QD-LED display that incorporated these QDs was also fabricated by ink-jet printing and exhibited clear moving images by passive matrix driving.
