An OLED device comprising a substrate, an anode electrode and a cathode electrode, a uniaxial alignment layer disposed between the anode electrode and the cathode electrode, a light-emitting layer disposed over the uniaxial alignment layer and capable of producing polarized light, and a carrier confinement layer disposed over the light emitting layer and wherein the carrier confinement layer blocks either holes, electrons, or excitons. The light-emitting layer includes an oligomeric fluorene or a mixture of oligomeric fluorenes.
