1. An electro-optical device, comprising:
a first light-emitting element configured to emit light in a first wavelength region;
a second light-emitting element configured to emit light in a second wavelength region shorter than the first wavelength region;
a third light-emitting element configured to emit light in a third wavelength region shorter than the second wavelength region;
a fourth light-emitting element configured to emit light in the first wavelength region;
a first filter configured to transmit light in the first wavelength region and light in the second wavelength region and absorb light in the third wavelength region; and
a second filter configured to transmit light in the first wavelength region and light in the third wavelength region and absorb light in the second wavelength region,
wherein the first light-emitting element, the second light-emitting element, the third light-emitting element, and the fourth light-emitting element are disposed in two rows and two columns in one pixel, and the first light-emitting element and the fourth light-emitting element are disposed diagonally with respect to an array direction of a plurality of pixels included in a display area of the electro-optical device,
wherein an array of the first light-emitting element, the second light-emitting element, the third light-emitting element, and the fourth light-emitting element is a Bayer array,
the first light-emitting element overlaps the first filter in a plan view,
the second light-emitting element overlaps the first filter in the plan view,
the third light-emitting element overlaps the second filter in the plan view,
the fourth light-emitting element overlaps the second filter in the plan view,
the first filter and the second filter are arranged alternately in a stripe pattern along a row direction of the Bayer array, and
each of the first filter and the second filter has a long shape extending in a column direction of the Bayer array.
