Abstract

A functional panel comprises a convex lens, an insulating film, a first region configured to emit first light of a first light emitting element, and a second region configured to emit second light of a second light emitting element. The insulating film is interposed between the convex lens and at least one of the first region and the second region; the convex lens and the first region overlap each other; the convex lens and the second region overlap each other; the convex lens has a first length in a first direction; the convex lens has a second length in a second direction; the second direction is perpendicular to the first direction; the first length is larger than the second length; and the first region and the second region are aligned in the first direction.
