Abrégé
(EN)
The invention provides an OLED display panel. The OLED display panel comprises a plurality of sub-pixels arranged in an array mode, wherein each sub-pixel comprises a substrate, a TFT layer arranged on the substrate, a flat layer arranged on the TFT layer, a first electrode arranged on the flat layer, a pixel definition layer arranged on the first electrode and the flat layer, a light emitting layer arranged on the first electrode, a transparent second electrode arranged on the light emitting layer and the pixel definition layer, and a packaging layer arranged on the second electrode, whereina part of at least one of the light emitting layer and the pixel definition layer is formed by a black shading material; since that a part of at least one of the light emitting layer and the pixel definition layer is formed by a black shading material, on the premise that the light emitting efficiency is not reduced, the OLED display panel is prevented from reflecting ambient light, and the watching experience of the OLED display panel is improved.
