Kind Code:
A1
Abstract:
A display substrate, comprising a pixel defining layer, a plurality of light-emitting devices, a first isolation portion and a light adjusting layer. The pixel defining layer has a plurality of apertures. A part of one light-emitting device is located in one aperture, and the light-emitting device comprises a first light-emitting layer and a cathode which are stacked. The first isolation portion is provided on the pixel defining layer and located between two adjacent apertures, and the first isolation portion isolates the first light-emitting layer and the cathode of the light-emitting device located in the two adjacent apertures. The light adjusting layer covers the pixel defining layer, the plurality of light-emitting devices and the first isolation portion. The refractive index of the light adjusting layer is different from that of the first isolation portion.
