Organic light-emission device
Disclosed is an organic light-emission device including a first electrode, a second electrode, and the light-emission layer interposed therebetween, wherein the light-emission layer contains a mesogenic polymer-based light-emission material and a chiral dopant, wherein the light-emission layer has one face facing the first electrode and an opposite face facing the second electrode, wherein molecules of the mesogenic polymer-based light-emission material in the one face are orientated in a first predetermined direction, while molecules of the mesogenic polymer-based light-emission material in the opposite face are orientated in a second predetermined direction different from the first predetermined direction, wherein an angle of the second predetermined direction relative to the first predetermined direction is defined as a twisted angle, and wherein molecules of the mesogenic polymer-based light-emission material are vertically arranged in a spirally twisted manner within the twisted angle between the one and opposite faces of the light-emission layer to form a twisted structure.
