Abstract
The present invention provides a light-emitting device suppressing the reduction in the light output while improving the response speed. As shown in FIG., the light-emitting device comprises four square element regions arranged with the sides of the element regions aligned in a two by two lattice. The light-emitting regions are disposed in the vicinity of corners at the center side of the element regions, and the light-emitting regions are localized in the vicinity of the center in the entire element region. A plane pattern of each of the light-emitting regions is formed so that plane patterns of p-electrodes and n-electrodes are not disposed in a region sandwiched by the light-emitting regions.
