We synthesized new materials of Zn(HPB)2 and Ir-complexes as blue or red emitting material. We fabricated white Organic Light Emitting Diodes (OLED) by using Zn(HPB)2 for the blue emitting layer, Ir-complexes for the red emitting layer and Alq3 for the green emitting layer. We fabricated white OLED by using double emitting layers of Zn(HPB)2:Ir-complexes and Alq3. The doping rate of Ir-complexes was varied, such as 0.2%, 0.4%, 0.6%, and 0.8%, respectively. When the doping rate of Zn(HPB)2:Ir-complexes was 0.6%, white emission was achieved. The Commission Internationale de l`Eclairage (CIE) coordinates of the white emission was (0.322, 0.312).
