In this paper, we realized a transparent white light emitting device (WOLED) using a single blue emitting layer DPVBi doped with DCJTB. Color turning was done by controlling the thickness of DCJTB doped in DPVBi layer. Transparent electrodes were adapted ITO as anode and Ca-Ag thin layer as cathode. We fabricated transparent WOLED having good color properties, (0.33, 0.30) viewed through Ca-Ag cathode side and (0.36, 0.34) viewed through the ITO anode side, respectively.
