Abstract
An electro-optical device includes a first light-emitting element including a first light-emitting region, a second light-emitting element including a second light-emitting region, a first filter, and a second filter. The area of the first light-emitting region is smaller than the area of the second light-emitting region, and a relationship (Lf11−Le11)>(Lf21−Le21) is satisfied when the length of the first light-emitting region is Le11, the length of the second light-emitting region is Le21, the length of the first filter is Lf11, and the length of the second filter is Lf21.
