An object of the present invention is to provide a lighting device that can suppress uneven brightness. The lighting device of the present invention includes a LED 22 having a light emitting surface 22A, a light guide plate 50 having a light entrance surface 50D and a light exit surface 50A, and a reflection-type polarizing sheet 43 covering at least a part of the light exit surface 50A of the light guide plate 50. Light emitted from the light emitting surface 22A enters the light entrance surface 50D facing the light emitting surface 22A. The light in the light guide plate 50 exits through the light exit surface 50A. A light-source-side peripheral end 43A of the reflection-type polarizing sheet 43 is located farther from the LED 22 than a light-source-side peripheral end of the light guide plate 50, whereby a peripheral end portion of the light guide plate 50 has a sheet-non-overlapping area T1 that does not overlap with the reflection-type polarizing sheet 43.
