We developed cadmium-free quantum dot light-emitting diodes (QD-LEDs) whose emitting layers are composed of QDs and an organic electron-transporting material. Wide area coverage (~80%) of color reproduction area specified in Recommendation ITU-R BT.2020 was achieved by fabricated red, green, and blue QD-LEDs.
