    摘要: The present disclosure provides an OLED display substrate, a method for preparing the same, and a flexible display device, and belongs to the technical field of display. The OLED display substrate includes a base substrate, and a thin film transistor, a first electrode and a light emitting layer sequentially arranged on the base substrate, the thin film transistor including an active layer, in which the OLED display substrate further includes a light shielding layer arranged between the active layer and the first electrode, and the light shielding layer also serves as an insulating layer of the OLED display substrate. The technical solution of the present disclosure is capable of ensuring the display effect of the display device.
