Display panel and display device

A display device comprising the display panel, wherein the display panel comprises:

• a substrate;
• light-emitting units on a side of the substrate;
• a black matrix, located on a side of the light-emitting units away from the substrate, and provided with black matrix openings, wherein a black matrix opening of the black matrix openings corresponds to a light-emitting unit of the light-emitting units;
• and
• a filter layer, comprising color-resistance units disposed in the black matrix openings and at least partially overlap with the light-emitting units of the same color in a direction perpendicular to a plane of the display panel;
• wherein a color-resistance unit of the color-resistance units comprises microparticles having a particle size, and a different between the particle size and a wavelength of light emitted by a corresponding light emitting unit is within a preset range, and the light-emitting units of different colors correspond to different particle sizes of the microparticles of the color-resistance units;
• wherein the color-resistance units comprise a first color color-resistance unit and a second color color-resistance unit;
• wherein the display panel comprises a first display area and a second display area;
• wherein a difference between a concentration of microparticles in the first color-resistance unit located in the first display area and a concentration of microparticles in the first color-resistance unit located in the second display area is n1;
• wherein a difference between a concentration of microparticles in the second color-resistance unit located in the first display area and a concentration of microparticles in the second color-resistance unit located in the second display area is n2;
• and
• wherein n1/n2.
