Abstract: A top-emitting OLED device includes: a substrate; a first electrode disposed on the substrate; an organic layer disposed on the first electrode; and a second electrode disposed on the organic layer, through which light emitted from the organic layer exits from the OLED device; wherein the first electrode comprises a curved structure recessed towards the substrate. The top-emitting OLED device can reduce the viewing angle dependence of the top-emitting OLED device, so that it can prevent color difference of exiting light, narrowed visual angle of the OLED device and lateral light leakage from occurring.

Abstract: The present disclosure discloses a pixel defining layer, a display substrate, and manufacturing methods thereof, and relates to the field of display technology. The pixel defining layer includes: a defining layer body, and a temperature-sensitive polymer layer located on an inner side surface of the defining layer body. The temperature-sensitive polymer layer has a solution temperature threshold, and the hydrophilicity and hydrophobicity of the temperature-sensitive polymer layer are different under temperatures of the temperature-sensitive polymer layer higher and lower than the solution temperature threshold. By changing the temperature of the temperature-sensitive polymer layer to be higher or lower than the solution temperature threshold thereof, the temperature-sensitive polymer layer is converted from hydrophilic to hydrophobic. Thus, the pinning effect of the raw material solution on the inner side surface of the defining layer body is reduced and the thickness uniformity of the pixel layer is improved.
