Abstract
A light-emitting device includes an inner light-emitting element having an n-sided polygonal shape (n is an integer of 3 or more) in a plan view with a peak emission wavelength in a range of 490 nm to 570 nm; m (m is an integer of 3 or more) outer light-emitting elements with a peak emission wavelength of 430 nm or greater and less than 490 nm; and a first phosphor with a peak emission wavelength in a range of 580 nm to 680 nm covering the inner light-emitting element and the m outer light-emitting elements. Each of n lateral surfaces of the inner light-emitting element faces a corresponding one of the m outer light-emitting elements in a top view.
