ELECTROLUMINESCENT SUBSTRATE AND ELECTROLUMINESCENT DEVICE COMPRISING SAME

The present disclosure relates to an electroluminescent substrate and an electroluminescent device comprising same. The electroluminescent substrate comprises a substrate layer comprising a pixel driving circuit and a plurality of pixel areas arranged in an array on the substrate layer; the pixel areas are defined by pixel isolation structures; at least a part of each pixel area comprises a first electrode layer, a first insulating layer located on the first electrode layer and a plurality of blank layers; the blank layers are defined by at least part of the first insulating layer and are separated from each other; the thickness of each pixel isolation structure is greater than the thickness of the first insulating layer; and an interval is provided inside the corresponding first electrode layer in at least a part of each pixel area. By means of the combination of pixel isolation structures and a first insulating layer, the advantages of the pixel isolation structures and of the first insulating layer can be
