Display panels and display devices

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

• a panel body comprising a display area;
• and
• a light-splitting component disposed on a light-emitting side of the panel body and covering at least the display area, wherein the light-splitting component comprises a plurality of light-splitting members arranged along a first direction, and each of the light-splitting members comprises a first side edge and a second side edge disposed opposite to each other along the first direction;
• for any two adjacent light-splitting members, a distance between the first side edge of one of the two adjacent light-splitting members and the first side edge of another one of the two adjacent light-splitting members along the first direction is defined as a preset distance, X, and the preset distance satisfies the following equation:
• X
• ≤
• θ
• ⁢
• Y
• ;
• wherein θ indicates angular resolution of human eye, and Y indicates an optimal viewing distance for the human eye.
