Display panel and display device

A display panel comprising:

• a substrate;
• a reflective plate disposed on the substrate;
• and
• a plurality of light-emitting elements disposed on the reflective plate,
• wherein the reflective plate includes a first reflective area and a second reflective area,
• wherein the first reflective area has a reflectance of light of a wavelength of 550 nm greater than a reflectance of light of a wavelength of 550 nm of the second reflective area, and
• wherein some of the plurality of light-emitting elements are disposed to overlap the first reflective area, while the others of the plurality of light-emitting elements are disposed to overlap the second reflective area.

A display device comprising:

• a substrate;
• a thin-film transistor including source and drain electrodes;
• a reflective plate electrically connected to one of the source and drain electrodes;
• a light-emitting element disposed on the reflective plate;
• and
• a connection electrode electrically connecting the reflective plate and the light-emitting element to each other,
• wherein the reflective plate includes a first reflective area and a second reflective area,
• wherein the first reflective area has a reflectance of light of a wavelength of 550 nm greater than a reflectance of light of a wavelength of 550 nm of the second reflective area, and
• wherein at least a partial area of the light-emitting element overlaps the first reflective area.
