要約
(EN)

Provided is a light-emitting device which can reduce grainy texture, suppress color unevenness and luminance unevenness. A light-emitting device according to the present invention includes: a board; a plurality of light-emitting parts each of which includes (i) a LED chip mounted on the board and (ii) a phosphor-containing resin including a light wavelength converter and covering the LED chip. Further, the light-emitting device includes a light-guiding member provided on the board, between the light-emitting parts which are adjacent to each other. Furthermore, the light-guiding member is formed to cover part of the phosphor-containing resin.
