Color filter substrate and display panel

A color filter substrate, comprising:

• a substrate, having a display area and a peripheral area located at at least one side of the display area, wherein the display area has at least one first region, and the peripheral area has at least one second region;
• a plurality of first photo spacers, disposed on the display area of the substrate, wherein at least one of the first photo spacers is located in the first region of the display area, and the first region has a first projection area A on the substrate;
• a plurality of second photo spacers, disposed on the peripheral area of the substrate, wherein at least one of the second photo spacers is located in the second region of the peripheral area, and the second region has a second projection area B on the substrate;
• a plurality of color photoresist patterns, disposed on the display area of the substrate, wherein in the first region, the color photoresist patterns are disposed at least partially around the at least one of the first photo spacers, and a projection area of the color photoresist patterns in the first region on the substrate is a, wherein (a/A)*100% is defined as a first coverage rate M;
• and
• at least one dummy-color photoresist pattern, disposed on the peripheral area of the substrate, wherein in the second region, the at least one dummy-color photoresist pattern is disposed at least partially around the at least one of the second photo spacers, and a projection area of the at least one dummy-color photoresist pattern in the second region on the substrate is b, wherein (b/B)*100% is defined as a second coverage rate N,
• wherein the first projection area A is substantially equal to the second projection area B, and 27% ≤(N-M)≤58%.
