Claim:
A lighting device, comprising: a light source; a chassis configured to house the light source therein and having an opening through which light emitted from the light source exits; an optical member provided so as to face the light source and cover the opening and having a surface including surface areas; a light reflecting portion provided on a side of the optical member close to the light source and configured to have different light reflectance in each of the surface areas; and a scattering structure formed on a side of the optical member opposite from the light source and configured to scatter the light; wherein the chassis has a surface facing the optical member and the surface including at least a first end portion, a second end portion, and a middle portion, the second end portion being located at an end away from the first end portion, and the middle portion being located between the first end portion and the second end portion; one or two of the first end portion, the second end portion and the middle portion are configured as light source installation areas in each of which the light source is arranged, and the rest is configured as an empty area in which no light source is arranged; the light reflecting portion is formed such that a portion of the optical member that overlaps the light source installation area has a light reflectance higher than a portion of the optical member that overlaps the empty area; and the light reflecting portion has a uniform light reflectance in a portion that overlaps the light source installation area.
