摘要： A method for manufacturing a display substrate comprises: forming a pixel definition layer on a lower surface of a base so as to define a pixel area; forming a spacer on a lower surface of the pixel definition layer; arranging a mask plate under the spacer; and moving an evaporation source along a first direction parallel to the lower surface of the base, so as to form an organic light emitting layer in the pixel area. When the evaporation source starts forming the organic light emitting layer in the pixel area, the spacer and the mask plate do not block a first border of the evaporation area. Further, when the evaporation source stops forming the organic light emitting layer in the pixel area, the spacer and the mask plate do not block a second border of the evaporation area.

摘要： A array substrate includes: a first sub-pixel, a second sub-pixel and a dummy sub-pixel that are located in a display region; a luminance attenuation degree of the first sub-pixel is greater than that of the second sub-pixel along a target direction; and a light-emitting layer of the dummy sub-pixel is configured to emit light having a color the same as that of light emitted by the first sub-pixel. As the dummy sub-pixel further includes the connecting electrode electrically connecting the pixel circuit with the light-emitting layer of the dummy sub-pixel the luminance attenuation of the first sub-pixel may be effectively compensated by driving the dummy sub-pixel to emit light.
