The present invention relates to an OLED display panel comprising a first electrode, and a first hole transporting layer, a second hole transporting layer, and an electron transporting layer stacked on the first electrode, and a second electrode formed; at least two light emitting units are provided on the second hole transporting layer; the electron transporting layer covers the light emitting units; the material of the electron transporting layer fills the gap(s) between adjacent light emitting units; the first hole transporting layer comprises a hole transporting material which has a hole mobility of 9×10−5-5×10−4 cm2/V·S, and a solubility of 10 g/L or more in a cleaning solvent at 25° C. The present invention utilizes a hole transporting material having a specific hole mobility as a common hole transporting layer, avoiding crosstalks between different pixels.
