Abstract
An organic light emitting diode (OLED) display device includes a flexible substrate, a thin-film transistor (TFT) layer, an OLED light emitting layer, a barrier layer, and an encapsulation layer. The encapsulation layer covers the barrier layer, and a portion of the encapsulation layer located at an outside of the barrier layer includes a first inorganic layer and a second inorganic layer. A protection layer is disposed on a portion of the first inorganic layer over surface the barrier layer, and the protection layer completely covers the barrier layer.
