PURPOSE: An organic electro luminescence device is provided to improve luminous efficiency by forming a2 stack architecture through a photoluminescence layer. CONSTITUTION: A first electrode(10) and a second electrode(20) which each other faces are prepared. A first light-emitting layer(130) is arranged between the first electrode and the second electrode. The first light-emitting layer generates a first light. The second light-emitting layer(250) Is interstratified between the first electrode and the second electrode. The second light-emitting layer generates a second light. A photoluminescence layer(230) generates a third light by using the first light. |
