1. A light-emitting device comprising:
a transistor over a substrate, the transistor comprising an oxide semiconductor;
a light-emitting element over the transistor; and
a color filter overlapping with the light-emitting element,
wherein the light-emitting element comprises:
a first light-emitting layer comprising a first light-emitting substance;
a second light-emitting layer over the first light-emitting layer, the second light-emitting layer comprising a second light-emitting substance;
a third light-emitting layer over the second light-emitting layer, the third light-emitting layer comprising a third light-emitting substance; and
a fourth light-emitting layer over the third light-emitting layer, the fourth light-emitting layer comprising a fourth light-emitting substance, and
wherein the second light-emitting layer and the third light-emitting layer are adjacent to each other without an electrode therebetween.
