The invention provides a pixel structure of an OLED display panel and a manufacturing process of the pixel structure. The pixel structure comprises a pixel area, and an anode conducting layer and a cathode conducting layer of a pixel unit; the pixel area comprises adjacent sub-pixel areas adjacent successively, at least two adjacent sub-pixel areas form a sub-pixel area group, and the sub-pixel areas in the sub-pixel area group are arranged in an integrated manner; the anode conducting layer is arranged in the pixel area, and the anode conducting layers are separated from one another; the cathode conducting layer and the anode conducting layer are electrically connected to control the pixel unit; the pixel unit comprises sub-pixels, and is arranged in the pixel unit, each sub-pixel is arranged in one sub-pixel area, and sub-pixels arranged in the same pixel area group are integrated in modeling and the same in color; and the pixel unit comprises a cavity implantation layer, a luminescent layer and an electron injecting layer.
