Display panel and display apparatus for improving color deviation

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;
• for a contacting surface of the first refracting portion and the second refracting portion, and for a displaying surface of the display panel, an angle between the contacting surface and the displaying surface is an acute angle or an obtuse angle;
• for the light-emitting devices in one light-emitting unit, a diffusion distance of at least one light-emitting device is less than diffusion distances of the other light-emitting devices;
• wherein the diffusion distance refers to a distance between a boundary of the orthographic projection of the light-emitting device on the substrate and a boundary of the orthographic projection of the first refracting portion on the substrate;
• wherein the light-emitting unit comprises a red light-emitting device, a green light-emitting device and a blue light-emitting device;
• and a diffusion distance of the red light-emitting device is less than a diffusion distance of the green light-emitting device, and a diffusion distance of the red light-emitting device is less than the diffusion distance of the blue light-emitting device.
