Provided is a liquid crystal display device capable of improving image quality of a display screen while reducing the number of light sources. A light source mounting substrate (42) formed on a backlight unit (4) has an elongated shape having a longitudinal direction aligned in a vertical scanning direction of the image, and has LED modules serving as light sources disposed at a plurality of positions in the longitudinal direction. A lens (45) is disposed above each of the light sources, for expanding light of the light source toward a region elongated in a horizontal scanning direction. A control device for controlling brightness of the plurality of light sources controls a light emission operation of the light sources in synchronization with selection of a scanning line in an operation of writing an image signal into the liquid crystal panel (2).
