An organic light emitting device and a manufacturing method thereof are provided to reduce a size of a display device by decreasing a size of a photodiode. An organic light emitting device includes a substrate(100), a transistor, an OLED(Organic Light Emitting Diode), a photodiode, and a reflective film(110). The transistor is formed on the substrate and includes a gate, a source, and a drain. The OLED is connected to the transistor and includes a first electrode(180), an organic film(210), and a second electrode(220). The photodiode generates an electrical signal according to incident light. The reflective film is formed under the photodiode and reflects the incident light toward the photodiode. A brightness of the light emitted from the OLED is varied according to the electrical signal from the photodiode. |
