Abstract
An organic light-emitting diode (OLED) display device is provided in the present invention, including a flexible substrate, a thin film transistor (TFT) layer, an OLED light emitting layer, a light extraction film layer, an inorganic protection film layer, and a packaging film layer. The light extraction film layer includes a first light extraction film layer and a second light extraction film layer. A nano-imprint process is performed on the second light extraction film layer to form a micro-lens array. The present invention also provides a manufacturing method of the OLED display device.
