Abstract: Disclosed is an organic light emitting display device in which water is prevented from externally permeating thereinto. The organic light emitting display device comprises a first substrate on which an organic light emitting diode and a driving device designed to drive the organic light emitting diode are formed; a second substrate facing the first substrate; a viscosity layer interposed between the first substrate and the second substrate to cover entire areas of the first substrate and the second substrate, the viscosity layer including a filler capable of water absorption; and a first adhesion layer arranged to adhere the viscosity layer to the first substrate, wherein the viscosity layer is a material including a cross-linkage functional group and having a viscosity characteristic at room temperature.

Abstract: A light emitting device including a first electrode and a second electrode facing each other, a blue fluorescent light emitting layer and a non-blue phosphorescent light emitting layer in contact with each other between the first electrode and the second electrode, a first common layer between the first electrode and the non-blue phosphorescent light emitting layer, and a second common layer between the blue fluorescent light emitting layer and the second electrode. The non-blue phosphorescent light emitting layer includes a first host, and a first dopant having a first triplet excitation level and a first singlet-triplet excitation level difference. The blue fluorescent light emitting layer includes a second dopant having: a second singlet-triplet excitation level difference that is smaller than the first singlet-triplet excitation level difference, and a second triplet excitation level that is higher than the first triplet excitation level, and a second host.
