The utility model provides a Micro OLED full-color display structure, comprising a substrate provided with a driving circuit, and an anode layer, a pixel definition layer, an electron hole injection layer, an electron hole transmission layer, a luminescent layer, an electron transmission layer, a cathode layer, a micro-cavity optical adjustment layer and a packaging layer which are arranged on the substrate from bottom to top in sequence. The anode layer comprises a plurality of pixel units with different thicknesses, the pixel definition layer covers gaps among the pixel units of the anode layer, pixel openings are etched above the pixel units and expose the pixel units, each pixel opening is in a trapezoid shape with a wide upper part and a narrow lower part, and the pixel definition layer is arranged between the pixel openings and the anode layer. And the height of the pixel definition layer is higher than that of the light-emitting layer in the pixel opening. According to the Micro OLED full-color display
