Display panel, manufacturing method thereof, and display apparatus

A display panel, comprising:

• a substrate, comprising a main surface;
• a plurality of sub-pixels, arranged in an array on the main surface of the substrate, wherein each of the plurality of sub-pixels comprises a light-emitting device and a color filter on a light-emitting side of the light-emitting device;
• the color filter of the plurality of sub-pixels comprises a first color filter and a second color filter that are adjacent, light transmission color of the first color filter and light transmission color of the second color filter are different from each other, and light transmittance of the second color filter is smaller than light transmittance of the first color filter;
• the first color filter comprises a first light-transmitting portion and a first peripheral portion, the first light-transmitting portion is configured to allow light of the sub-pixel where the first light-transmitting portion is located to pass through to emit from the display panel;
• the first peripheral portion at least partially surrounds the first light-transmitting portion, and comprises a first portion located on a side of the first light-transmitting portion close to the second color filter;
• the second color filter comprises a second light-transmitting portion and a second peripheral portion, the second light-transmitting portion is configured to allow light of the sub-pixel where the second light-transmitting portion is located to pass through to emit from the display panel;
• the second peripheral portion at least partially surrounds the second light-transmitting portion, and comprises a first portion located on a side of the second light-transmitting portion close to the first color filter;
• the first portion of the second peripheral portion comprises a plurality of sub-layers that are at least partially overlapped and spaced apart from each other in a longitudinal direction perpendicular to the main surface of the substrate, the plurality of sub-layers comprise a first sub-layer and a second sub-layer, and at least a part of the first portion of the first peripheral portion is located between the first sub-layer and the second sub-layer in the longitudinal direction.
