ORGANIC LIGHT-EMITTING DEVICE

摘要

Provided is an organic light emitting device, which shows improved blue light emission efficiency and luminance while maintaining other characteristics such as a color coordinate. The organic light emitting device comprises: a first electrode(10); a first organic layer(40) formed on the first electrode and comprising a first compound with a maximum wavelength of 400-500 nm as measured by photoluminescence(PL) spectrum; a blue light emitting layer(30) formed on the first organic layer; a second organic layer(50) formed on the blue light emitting layer and comprising a second compound with a maximum wavelength of 400-500 nm as measured by PL spectrum; and a second electrode(20) formed on the second organic layer.
