Organic light emitting diode display and manufacturing method thereof

An organic light emitting diode display comprising:

• a substrate;
• a thin film transistor provided on the substrate;
• a first electrode connected to the thin film transistor;
• an organic emission layer provided on the first electrode;
• an interlayer provided on the organic emission layer;
• an electron auxiliary layer provided on the interlayer;
• and
• a second electrode provided on the electron auxiliary layer, wherein
• the interlayer comprises a mixture of a host material of the organic emission layer and the electron auxiliary layer.

A method for manufacturing an organic light emitting diode display, comprising:

• forming a thin film transistor and a first electrode on a substrate;
