Abstract
A blue light emitting display element has a hetero p-n junction type light emitting layer formed between a semiconductor layer of a II-VI or III-V semiconducting compound having a wide energy bandgap and a highly electroconductive amorphous silicon type semiconductor layer which is of opposite conduction type and capable of forming a substantially ohmic contact with the semiconducting compound.
Claims12
A blue light emitting diode consisting essentially of:
- a semiconductor layer of a first conduction type composed of a II-VI or III-V semiconducting compound having a wide energy bandgap;
- a highly electroconductive amorphous silicon type semiconductor layer of a second conduction type stacked on said semiconductor layer of a first conduction type, said first and second conduction types being different, said semiconducting compound and said amorphous silicon type semiconductor layer being able to form a p-n junction therebetween;
- a first electrode formed on said amorphous silicon type semiconductor layer of a second conduction type;
- and
- a second electrode formed under said semiconductor layer of a first conduction type.
