Abstract:
A display panel includes a plurality of light-emitting elements. Light emitted from a first light-emitting element has a CIE 1931 chromaticity coordinate x of greater than 0.680 and less than or equal to 0.720 and a CIE 1931 chromaticity coordinate y of greater than or equal to 0.260 and less than or equal to 0.320. Light emitted from a second light-emitting element has a CIE 1931 chromaticity coordinate x of greater than or equal to 0.130 and less than or equal to 0.250 and a CIE 1931 chromaticity coordinate y of greater than 0.710 and less than or equal to 0.810. Light emitted from a third light-emitting element has a CIE 1931 chromaticity coordinate x of greater than or equal to 0.120 and less than or equal to 0.170 and a CIE 1931 chromaticity coordinate y of greater than or equal to 0.020 and less than 0.060.
