Abstract

The present disclosure provides a blue light organic light-emitting diode, which includes a first electrode layer; a first hole injection layer disposed on the first electrode layer; a second hole injection layer disposed on first hole injection layer; a hole transport layer disposed on the second hole injection layer; a blue light emitting material layer disposed on the hole transport layer; an electron transport layer disposed on the blue light emitting material layer; and a second electrode layer disposed on the electron transport layer, wherein the second hole injection layer has a thickness of 85 nm˜105 nm. The present disclosure further provides a display including the device. The blue light organic light-emitting diode of the present disclosure can control blue light energy components having a wavelength less than 435 nm within 0.2%, which reduces the harm of the blue light in the wave band to human eyes to a great extent.
