Display panel and display device

A display device, comprising:

• a power supply assembly and a display panel;
• wherein
• the display panel comprises:
• a base substrate;
• a plurality of sub-pixels disposed on the base substrate, wherein each of the plurality of sub-pixels comprises a light-emitting region, wherein an orthographic projection of the light-emitting region on the base substrate is in an elongated-structure shape, a length of the elongated-structure in a first direction is different from a length of the elongated-structure in a second direction;
• and
• a plurality of microlens structures disposed on a side, away from the base substrate, of the plurality of sub-pixels and in one-to-one correspondence to the plurality of sub-pixels, wherein an orthographic projection of each of the plurality of microlens structures on the base substrate covers an orthographic projection of the light-emitting region of the corresponding sub-pixel on the base substrate;
• wherein a length of the orthographic projection of each of the plurality of microlens structures on the base substrate in the first direction is different from a length of the orthographic projection of the each of the plurality of microlens structures on the base substrate in the second direction, and each of the plurality of microlens structures comprises a curved surface away from the base substrate, wherein a curvature of the curved surface in the first direction is different from a curvature of the curved surface in the second direction, the first direction being intersected with the second direction;
• and
• the power supply component is configured to supply power to the display panel.
