<p>PURPOSE: An organic light emitting diode display device is provided to reduce power consumption by lowering a driving voltage needed for light emission. CONSTITUTION: A first electrode(120) is located on a substrate. A light emitting layer(133) is located on a first electrode. A second electrode(140) is located on the light emitting layer. A hole related layer is in charge of the injection and transportation of a hole. An electron related layer is in charge of the injection and transportation of an electron. The light-emitting layer divided into a host layer and a guest layer through an available process.</p>
