Light-emitting device and electronic device

A light-emitting device comprising:

• a plurality of substrates;
• a first light-emitting element, a second light-emitting element, a third light-emitting element, and a fourth light-emitting element between the plurality of substrates;
• and
• a plurality of color filters overlapping with the first light-emitting element, the second light-emitting element, and the third light-emitting element,
• wherein the first light-emitting element, the second light-emitting element, the third light-emitting element, and the fourth light-emitting element each share an EL layer,
• wherein the light-emitting device is capable of displaying, on CIE1931 chromaticity coordinates, a color gamut within a triangle formed by connecting (x, y) chromaticities of approximately (0.713, 0.287) to (0.182, 0.786) to (0.141, 0.045) to (0.713, 0.287) for a BT.2020 area ratio of approximately 100%.
