An organic electroluminescent display panel comprises a substrate, an anti-reflective layer, a light-shielding layer, a transistor and an organic light emitting diode. A method for fabricating said organic electroluminescent display panel comprises forming the anti-reflective layer on the substrate; forming the light-shielding layer with a first region and a second region on the anti-reflective layer; and then, removing at least part of the light-shielding layer to expose at least part of anti-reflective layer in the first region. After that, the transistor is formed above the light-shielding layer in the second region, and the organic light emitting diode is formed above the anti-reflective layer in the first region.
