Display panel and electronic device including the same

A display panel comprising a light emitting panel, and a color conversion panel with a surface opposite a surface of the light emitting panel,

• wherein the light emitting panel is configured to emit incident light including a first light with a luminescent peak wavelength greater than or equal to about 450 nm and less than or equal to about 480 nm, and a second light with a luminescent peak wavelength of greater than or equal to about 500 nm and less than or equal to about 580 nm,
• wherein the color conversion panel comprises a color conversion layer comprising a color conversion region, and optionally, a partition wall defining each region of the color conversion layer,
• wherein the color conversion region comprises a first region corresponding to a red pixel, and the first region comprises a first composite comprising a matrix and a plurality of luminescent nanostructures dispersed in the matrix,
• wherein a UV-Vis absorption spectrum of the plurality of the luminescent nanostructures includes a first absorption peak in a range of greater than or equal about 580 nanometers and less than or equal to about 630 nanometers, and
• wherein in the UV-Vis absorption spectrum, an absorbance ratio at a wavelength of about 520 nm with respect to a wavelength of about 350 nm is greater than or equal to about 0.04:1.
