ORGANIC LIGHT-EMITTING DEVICE

Title:

ORGANIC LIGHT-EMITTING DEVICE

Document Type and Number:

WIPO Patent Application WO/2011/036868

Kind Code:

A1

Abstract:

An organic light-emitting device includes an anode, a cathode, and an organic compound layer including at least a light-emitting sublayer and being arranged between the anode and the cathode, the light-emitting sublayer containing a host serving as a main component, a first dopant, and a second dopant, in which for the host, the first dopant, and the second dopant, the following relationships (a) to (c) hold, whereby only the second dopant emits light: (a) first maximum emission wavelength (H) < first maximum emission wavelength (D1) < first maximum emission wavelength (D2), (b) LUMO (D2) < LUMO (D1) < LUMO (H), and (c) HOMO (D2) is equal to or lower than HOMO (H) < HOMO (D1).
