Abstract

The present disclosure provides an OLED display substrate, a fabricating method thereof and a display device. The OLED display substrate includes a substrate; an inorganic layer and a light-emitting unit on substrate, light-emitting unit being on a side of inorganic layer away from substrate and including a light-emitting structure; a camera on a side of substrate away from inorganic layer, and light-emitting unit being not in orthographic projection region; a protective layer in orthographic projection region and on side of inorganic layer away from substrate, wherein protective layer is configured to protect inorganic layer in orthographic projection region from warping or cracking in a process of removing part of light-emitting structure in orthographic projection region by laser cutting.
