Abstract:
A display apparatus, a display substrate and a manufacturing method therefor are provided. The display substrate comprises: a driving back plate, having a first driving area and a second driving area; a first electrode pattern, comprising a plurality of transparent first electrodes and a second electrode; a light emitting layer, comprising a first light emitting portion in the first driving area and a second light emitting portion in the second driving area; a second electrode pattern, comprising a plurality of transparent third electrodes in the first driving area and a fourth electrode located in the second driving area. The first electrode, the first light emitting portion and the third electrode corresponding to the first driving area constitute a Passive matrix organic light-emitting diode structure.
