Abstract
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.
