Oled display and manufacturing method thereof

A manufacturing method of an organic light-emitting diode (OLED) display comprising a plurality of sub-pixel units, the method comprising:

• forming a first electrode and a third electrode on a base substrate in a first region and a second region of each of the sub-pixel units respectively;
• the first electrode and the third electrode both comprising an opaque metal layer;
• forming a first organic material functional layer and a second organic material functional layer in the first region and the second region respectively on the substrate formed with the first electrode and the third electrode, and
• forming a second electrode and a fourth electrode in the first region and the second region respectively on the substrate formed with the first organic material functional layer and the second organic material functional layer, the second electrode and the fourth electrode both being translucent metal electrodes,
• wherein the first electrode, the first organic material functional layer and the second electrode constitute a first micro-cavity, the third electrode, the second organic material functional layer and the fourth electrode constitute a second micro-cavity, and the first micro-cavity and the second micro-cavity have different thicknesses.
