A display device comprising a display panel, the display panel comprising:

• an array substrate, including a plurality of open areas and non-open areas between adjacent open areas;
• a display array on a side of the array substrate, the display array at least including a first light-emitting element, a second light-emitting element, and a third light-emitting element with different light-emitting colors, and the first light-emitting element, the second light-emitting element and the third light-emitting element being respectively in corresponding opening areas;
• an encapsulation layer covering the display array;
• a touch electrode layer on a side of the encapsulation layer away from the array substrate;
• a first planarization layer covering the touch electrode layer;
• and
• a color-resist structure on a side of the first planarization layer away from the display array, the color-resist structure including a first color-resist layer, a second color-resist layer and a third color-resist layer, wherein:
• the first color-resist layer includes a first color-resist unit and a first block, in a direction perpendicular to a plane where the array substrate is located, the first color-resist unit at least partially overlaps the first light-emitting element, the first block at least partially overlaps the non-opening area;
• the second color-resist layer includes:
• a second color-resist unit and a second block, in the direction perpendicular to the plane where the array substrate is located, the second color-resist unit at least partially overlaps the second light-emitting element, and the second block at least partially overlaps the non-opening area;
