Abstract: An organic electroluminescent apparatus including an anode, a cathode, a first organic light emitting unit layer, a plurality of second organic light emitting unit layers, and a plurality of bonding layers is provided. The first organic light emitting unit layer has a phosphorescent host material for emitting blue light. The second organic light emitting unit layers have a host material for emitting light other than blue light. The first organic light emitting unit layer and the second organic light emitting unit layers are located between the anode and the cathode to obtain white light by mixing light. Each of the bonding layers is located between the first organic light emitting unit layer and one of the second organic light emitting unit layers or between two of the second organic light emitting unit layers.
