LIGHT EMITTING ELEMENT, METHOD FOR MANUFACTURING THE LIGHT EMITTING ELEMENT, OPTICAL ELEMENT AND METHOD FOR MANUFACTURING THE OPTICAL ELEMENT

摘要

Light emitting efficiency of a light emitting element is improved by simply forming a fine uneven shape on the surface of a light emitting surface. An LED element (10), for instance, is prepared as a light emitting body, and on a light emitting surface (18) of the LED element (10), a recording material layer (12) whose shape can be changed in heat mode is formed. Then, a plurality of recessed sections (15) are formed at a pitch 0.01-100 times the center wavelength of light emitted by the LED element (10), by irradiating the recording material layer (12) with collected light.
