PURPOSE: An organic electroluminescent(EL) display apparatus is provided to emit light with a superior color purity by including a fluorescent light emitting material which emits identical color to the color which is emitted from a phosphorescence light emitting material. CONSTITUTION: An organic EL device includes a red organic EL device, a green organic EL device and a blue organic EL device. The organic EL devices include a pair of electrodes, hole transport layers(305, 306) and a light emitting layer(301). The light emitting layers(308) of the green organic EL device include a delay fluorescent material. A micro-cavity is arranged between the electrodes of the green organic EL device. |
