Title:
表示基板を製造するための方法、表示基板及び表示装置
Document Type and Number:
Japanese Patent JP6877346
Kind Code:
B2
Abstract:
The present disclosure relates to a method for manufacturing a display substrate, a display substrate and a display device. The method 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. An acute angle between a side surface of the pixel definition layer in the first direction for defining the pixel area and the lower surface of the base is a first angle. An acute angle between a border of an evaporation area of the evaporation source in the first direction and the lower surface of the base is a second angle, wherein the second angle is greater than or equal to the first angle. 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.
