摘要： The present disclosure provides a display motherboard, a method for fabricating the same, and a method for aligning the same. The display motherboard includes an array substrate on which an alignment mark and a color film layer are provided. A portion of a black matrix of the color film layer in an alignment mark area includes a first light-shielding portion and a second light-shielding portion. The first light-shielding portion covers the alignment mark, and the second light-shielding portion covers an area outside the alignment mark, where upper surfaces of the first light-shielding portion and the second light-shielding portion are not in the same plane. When the display motherboard is aligned in the subsequent processes, since the black matrix forms the same pattern as the alignment mark due to a height step, when the exposure machine exposures, the pattern can be directly captured for alignment.

摘要： The present application provides display substrates and their manufacturing methods, and display devices. A display substrate includes a base substrate, an encapsulation layer, a filter layer and optical film layers. The encapsulation layer is located on the base substrate. The filter layer is located in the encapsulation layer. The filter layer includes black matrixes. The black matrixes include black matrix openings. The optical film layers are located on a side of the encapsulation layer away from the base substrate. The optical film layers are configured to transmit part of incident light and absorb part of the incident light. A light transmittance of the optical film layers is larger than that of the black matrixes. The optical film layers include optical film layer openings. Projections of the optical film layer openings on the base substrate are located within projections of the black matrix openings on the base substrate.
