Abstract:
1. A light emitting device comprising a light emitting element and a phosphor layer placed on a top surface of the light emitting element, the light emitting device being configured to convert a part of light outputted from the top surface of the light emitting element into a fluorescence and mix the light passing through the phosphor layer with the fluorescence and output the light with predetermined chromaticity, wherein, the phosphor layer contains phosphor particles laid along the top surface of the light emitting element, and a binder filled into a gap between the phosphor particles, and an area of a region being positioned at the gap between the phosphor particles is between or equal to 3% and 10% with respect to the area of an upper surface of the phosphor layer, the region allowing the light being outputted to pass through the binder and directly reach the upper surface of the phosphor layer.
