Display substrate and manufacturing method thereof, display panel and display device

A display substrate, comprising a plurality of pixels, wherein

• each of the plurality of pixels comprises a plurality of sub-pixels that emit light of different colors, and each of the plurality of sub-pixels comprises a light emitting element, the light emitting element comprises an upper electrode, a lower electrode, and a light emitting layer provided between the upper electrode and the lower electrode;
• each of at least two of the plurality of sub-pixels comprises a color filter, the color filter has a solid structure;
• without any opening, and the color filter covers at least a portion of a light emitting region of the light emitting element of the sub-pixel which comprises the color filter;
• a color of light emitted by the light emitting element of at least one of the at least two of the plurality of sub-pixels includes a color of the color filter of the at least one of the at least two of the plurality of sub-pixels;
• the plurality of sub-pixels that emit light of different colors comprise a red-light sub-pixel, a green-light sub-pixel, and a blue-light sub-pixel that respectively emit red light, green light, and blue light;
• the at least two of the plurality of sub-pixels include the green-light sub-pixel, the blue-light sub-pixel, and the red-light sub-pixel, and an overlapping area of the color filter and the light emitting region of the light emitting element of the green-light sub-pixel is less than an overlapping area of the color filter and the light emitting region of the light emitting element of the blue-light sub-pixel;
• and
• the color filter of the green-light sub pixel does not cover an entirety of the light emitting region of the light emitting element of the green-light sub-pixel but covers a center of the light emitting region of the light emitting element of the green-light sub-pixel, and the color filter of the blue-light sub-pixel does not cover an entirety of the light emitting region of the light emitting element of the blue-light sub-pixel but covers a center of the light emitting region of the light emitting element of the blue-light sub-pixel, and the color filter of the red-light sub-pixel covers an entirety of the light emitting region of the light emitting element of the red-light sub-pixel.
