Title:
LIGHT EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/115405
Kind Code:
A1
Abstract:
A first electrode (110) is an anode, and a second electrode (130) is a cathode. An organic layer (120) has a light emitting layer (125), hole injection layer (121: first functional layer), electron inhibition layer (124: second functional layer), and electron extraction layer (123: third functional layer). The hole injection layer (121) is positioned between the first electrode (110) and the light emitting layer (125), and contains a material wherein holes move. The electron inhibition layer (124) is positioned between the hole injection layer (121) and the light emitting layer (125), and contains a material that inhibits moving of electrons. The electron extraction layer (123) is positioned between the hole injection layer (121) and the electron inhibition layer (124), and contains a material wherein electrons move.
