Abstract: A light emitting device includes a base having a light reflecting surface and having a first side on which the light reflecting surface is provided, light sources mounted on the first side, and a half mirror disposed opposite to the base to reflect a part of incident light and to transmit another part of the incident light. Each of the light sources includes a reflecting layer on an upper surface of each of the light sources. The half mirror has an oblique reflectance with respect to wavelengths of light emitted from the light sources in a case where the light travels obliquely toward the half mirror. The half mirror has a perpendicular reflectance with respect to the wavelengths in a case where the light travels perpendicularly toward the half mirror. The oblique reflectance is smaller than the perpendicular reflectance.

Abstract: A display apparatus includes a first light source, a second light source, a third light source, a first color filter, a second color filter, a third color filter, and an opto-functional device. The first light source and the second light source are allowed to emit light in a first emission time period to form a first display pattern. The third light source is allowed to emit light and the opto-functional device controls the third color filter to transmit light in a second emission time period to form a second display pattern. The first emission time period and the second emission time period are alternately repeated to combine the first display pattern and the second display pattern to obtain an intended display pattern when the display apparatus displays the intended display pattern.
