Display substrate, fabricating method of display substrate, and display device

A display device, comprising:

• a display substrate, comprising:
• a base;
• at least one organic film layer at a side of the base;
• and
• a blocking dam, wherein:
• the base comprises a display area, a non-display area on at least one side of the display area, and an anti-cracking reinforcing area at an edge of the non-display area away from the display area;
• at least one organic film layer is in the anti-cracking reinforcing area, the at least one organic film layer being configured to block cracks from diffusing towards the display area;
• the blocking dam and the at least one organic film layer are on the same side of the base;
• the at least one organic film layer is further away from the display area relative to the blocking dam;
• the base comprises a first bottom layer, a second bottom layer, and a bottom barrier between the first bottom layer and the second bottom layer;
• the first bottom layer and the second bottom layer are formed of organic material comprising polyimide;
• and
• the bottom barrier is formed of inorganic insulating material, which is correspondingly removed from the anti-cracking reinforcing area.
