1. A method of manufacture OLED display device, comprising steps of:

  • step S1, providing a TFT substrate, the TFT substrate includes a substrate element and an anode layer positioned on the substrate element;

    step S2, forming an antireflective layer on the TFT substrate, and patterning the antireflective layer for forming a plurality of first openings exposing the anode layer;

    step S3, forming a negative photoresist material layer on the TFT substrate and the antireflective layer, and forming a pixel defining layer by exposure-and-development process to the negative photoresist material layer,wherein a plurality of second openings corresponding to the plurality of first openings are pass through and formed on the pixel defining layer, a plurality of pixel regions on the TFT substrate are defined by the plurality of second openings and the plurality of first openings positioned below the plurality of second openings; and

    step S4, forming an OLED emitting layer on the plurality of pixel regions of the TFT substrate.
