Display panel and display apparatus

A display panel, comprising:

• a substrate and a plurality of light-emitting units disposed on the substrate, wherein the light-emitting units comprises a plurality of light-emitting devices arranged in an array, and a barrier is disposed between neighboring light-emitting devices;
• a dimming layer disposed on a light-exiting side of the light-emitting unit;
• wherein the dimming layer comprises a plurality of first refracting portions arranged in an array, and a second refracting portion is disposed between neighboring first refracting portions and contacted with the first refracting portions;
• and orthographic projections of the first refracting portions on the substrate overlap with an orthographic projection of the barrier on the substrate, and an orthographic projection of the second refracting portion on the substrate overlaps with orthographic projections of the light-emitting devices on the substrate;
• wherein a refractive index of a material of the first refracting portion is less than a refractive index of a material of the second refracting portion.
