Abstract: The light-emitting device includes a first light-emitting element having an emission peak wavelength of 430 nm or more and less than 490 nm, a second light-emitting element having an emission peak wavelength of 490 nm or more and 570 nm or less, a support body at which the first light-emitting element and the second light-emitting element are disposed, and a light-transmissive member containing a red phosphor and covering the first light-emitting element and the second light-emitting element. A content density of the red phosphor in the light-transmissive member in a space between the first and second light-emitting elements is higher in a part below an upper surface of the second light-emitting element than in a part above the upper surface thereof.

Abstract: An image display device includes an imaging element, a light source that forms a floating image, a position detecting part, a driver, and a controller. The imaging element includes a base member including a first surface, and a reflector array on the base member; or a base member comprising a reflector array and including a first surface. The reflector array includes multiple reflector rows including multiple dihedral corner reflectors along a first direction. The reflector rows are arranged parallel to a second direction crossing the first direction. The dihedral corner reflectors each include a first reflecting surface, and a second reflecting surface orthogonal to the first reflecting surface.

Abstract: A light emitting device includes a mounting board, light sources, a light diffuser, a wavelength conversion layer, and scatter reflection portions. Each of the light sources has an upper face on which a light reflecting layer is disposed. The light diffuser is arranged above the plurality of light sources. The wavelength conversion layer is located at least between the light sources and the light diffuser. The wavelength conversion layer is configured to absorb at least a portion of light from the light sources and to emit light having a wavelength which is different from a wavelength of the light from the light sources. The scatter reflection portions are arranged on a surface of the wavelength conversion layer that is closer to the light diffuser. Each of the scatter reflection portions is arranged above at least a portion of the upper face of a corresponding one of the light sources.
