Abstract
An organic light-emitting diode (OLED) display panel and a manufacturing method thereof are provided. The OLED display panel includes an optical filter layer and a light-emitting layer stacked and disposed along a first direction. The optical filter layer includes a substrate, a first capping layer, and a color filter are sequentially stacked along the first direction. The light-emitting layer includes a second capping layer, a first electrode, a light-emitting functional layer, a hole transport layer, and a second electrode are sequentially stacked along the first direction. Thus, the light loss inside the OLED display panel can be reduced, and the light extraction efficiency can be improved.
