1. a kind of method for manufacturing organic light emitting diode display, the described method comprises the following steps:

  • Prepare substrate;

    Spacer is formed on the substrate in edge along substrate;

    The driving circuit and Organic Light Emitting Diode surrounded by spacer is formed on the substrate;

    Formed wrap film substantially to cover driving circuit and Organic Light Emitting Diode,Wherein, the mask used in the step of forming driving circuit, Organic Light Emitting Diode and wrap film is by spacer branchIt supports and is contacted with spacer,Wherein, the height ratio of spacer is by i) driving circuit, ii) Organic Light Emitting Diode and iii) stratiform that is formed of wrap filmThe height of structure is big,Wherein, the infiltration of wrap film and spacer blocking moisture and oxygen into Organic Light Emitting Diode and driving circuit, and nothingNeed another additional substrate.
