Claim:
1. A blue light organic light-emitting diode, comprising: a first electrode layer; a first hole injection layer disposed on the first electrode layer; a second hole injection layer disposed on the 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 first hole injection layer has a thickness which is substantially equal to 10 nm, and the second hole injection layer has a thickness which is between 90 nm to 95 nm such that a percentage of the energy of blue light having a wavelength less than 435 nm emitted from the blue light organic light-emitting diode is between 0.08%˜0.21%.
