Oled array substrate, production method thereof, and display apparatus

A method of producing an OLED array substrate, comprising steps of:

• providing a substrate;
• forming a plurality of pixel defining layers, which are provided at intervals on the substrate, on the substrate;
• and
• forming a conductive structure which is at least partly located in at least one of the plurality of pixel defining layers.

A display apparatus, comprising an OLED array substrate, the OLED array substrate comprising:

• a substrate;
• a plurality of pixel defining layers which are provided at intervals on the substrate;
• and
• a conductive structure which is at least partly located in at least one of the plurality of pixel defining layers.
