Title: METHOD FOR MANUFACTURING DISPLAY SUBSTRATE, DISPLAY SUBSTRATE, AND DISPLAY DEVICE
Abstract:
Disclosed are a method for manufacturing a display substrate, a display substrate, and a display device. The method comprises: forming a pixel defining layer (2) on a lower surface of a substrate (1) to define a pixel region; forming a spacer (3) on a lower surface of the pixel defining layer (2); disposing a mask below the spacer (3); and moving a vapor deposition source in a first direction in parallel to the lower surface of the substrate (1), so as to form an organic light-emitting layer (8). An acute angle between a side surface of the pixel defining layer (2) in the first direction and the lower surface of the substrate (1) is a first angle. An acute angle between a boundary (6', 6") of a vapor deposition region (6) of the vapor deposition source in the first direction and the lower surface of the substrate (1) is a second angle. The second angle is greater than or equal to the first angle. When the vapor deposition source begins forming the organic light-emitting layer (8) in the pixel region, the spacer (3) and the mask do not form a blockage on a first boundary (6') of the vapor deposition region (6). Likewise, when the vapor deposition source completes formation of the organic light-emitting layer (8) in the pixel region, the spacer (3) and the mask do not form a blockage on a second boundary (6") of the vapor deposition region (6).
