Abstract: Provided is an organic light-emitting diode (OLED) display device having sub-pixels with four colors. When a B1 sub-pixel that represents deep blue and a B2 sub-pixel that represents sky blue are formed, by using a high efficiency blue organic material to form the same emission material layers in both the B1 and B2 sub-pixels such that a microcavity effect is implemented only in the B2 sub-pixel and a sky blue peak is extracted from the high efficiency blue organic material of the B2 sub-pixel, the emission material layer of the B2 sub-pixel represents sky blue. Therefore, a process of depositing emission material layers is simplified, which leads to a short process time and a reduction of the cost of materials, resulting in improvement in process efficiency of the OLED display device.
