To provide: a light-emitting unit which can be made thin in a simple composition and which can reduce the occurrence of unevenness in luminance; a backlight having the light-emitting unit; and a liquid crystal display apparatus with the backlight.

A second translucent member 36 with a refractive index which is different from that of a resin sealing layer 35 is arranged in an optical path for light which is ejected from light ejecting surfaces 32a of the light-emitting elements 32. The optical path lies between a surface 35a on the opposite side of the side of the resin sealing layer 35 composing the light-emitting unit 22 which faces a substrate 31 and an installation surface 31a of the light-emitting elements 32. In addition, a bottom section reflecting member with inclined surfaces 33a and 33b inclining toward the installation surface 31a is arranged on the installation surface 31a of the substrate 31. Furthermore, side section reflecting members 34 with sidewall surfaces 34a which are inclined to proceed toward the light-emitting elements 32 as the sidewall surface 34a facing the light-emitting elements 32 goes from the installation surface 31a to the surface 35a of the resin sealing layer 35 are arranged on both sides of the light-emitting elements 32 along the lineup direction of the light-emitting elements 32 on the installation surface 31a of the substrate 31.
