Display substrate and display device

A display substrate, comprising:

• a base substrate;
• a first electrode located on a side of the base substrate;
• a light-emitting layer located on a side of the first electrode away from the base substrate;
• a second electrode located on a side of the light-emitting layer away from the base substrate;
• an optical extraction layer located on a side of the second electrode away from the base substrate;
• a protective layer located on a side of the optical extraction layer away from the base substrate;
• and
• an encapsulation layer comprising a first intercalation layer located on a side of the protective layer away from the base substrate and a second intercalation layer located on a side of the first intercalation layer away from the base substrate;
• wherein the display substrate comprises a color deviation adjustment layer configured to adjust a color deviation of the display substrate, so that the color deviation has a maximum value at an observation angle in a range of 0 to 90 degrees,
• wherein the color deviation adjustment layer comprises the first intercalation layer and the second intercalation layer which are located in the encapsulation layer, and the color deviation adjustment layer further comprises one of the group consisting of a film layer taken from the encapsulation layer except for the first intercalation layer and the second intercalation layer, the second electrode, the optical extraction layer, and the protective layer;
• wherein the first electrode comprises a reflective layer, and the second electrode comprises a transparent material, and
• wherein a thickness L1 of the first intercalation layer is less than a thickness L2 of the second intercalation layer.
