    Abstract: A white organic electro luminescence device and a method for manufacturing the same are provided to acquire a white light emitting characteristic having a high purity by forming a trap light emitting layer between a hole layer and an electron layer. A white organic electro luminescence device includes a substrate(210), a first electrode(220), hole layers(230,240), a light emitting layer(250), electron layers(260,270), and a second electrode(280). The first electrode(220) is formed on the substrate(210). The hole layers(230,240) are formed on the first electrode(220). The light emitting layer(250) has a dopant and a host, and has a trap light emitting layer(255) which is formed on an upper part of the positive hole to have a difference of energy level between the dopant and the host. The electron layers(260,270) are formed on the upper part of the light emitting layer(250). The second electrode(280) is formed on the electron layers(260,270).
