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.
Claims15
An electro-optical device comprising:

- a second light-emitting element configured to emit second light from a second light-emitting region;
- a first filter configured to transmit, of the first light, light in a first wavelength region;
- and
- a second filter configured to transmit, of the second light, light in a second wavelength region different from the first wavelength region, wherein
- an area of the first light-emitting region is smaller than an area of the second light-emitting region, and
- (Lf11−Le11)>(Lf21−Le21), where a length of the first light-emitting region along a first axis is Le11, a length of the second light-emitting region along the first axis is Le21, a length of the first filter along the first axis is Lf11, and a length of the second filter along the first axis is Lf21.
