Abstract: A white organic light emitting diode (OLED) display device and a method of manufacturing the same are provided. By making an organic fluorescent color conversion film including a first conversion film and a second conversion film respectively disposed on a green color resist and a red color resist, the first conversion film converts cyan light into green light, and the second conversion film converts yellow orange light into red light. This can improve color gamut and color conversion rate of the white OLED display device and improve density of the organic color conversion film and stability of a device.
