PROBLEM TO BE SOLVED: To suppress an increase in the instantaneous power consumption of a backlight subjected to a local dimming control.SOLUTION: A light source control device for controlling a plurality of light sources, a brightness of each of the light sources being independently controllable by changing a ratio of a turn-on period to a turn-off period, comprises: determination means determining the brightness of each light source in response to an image signal, and determining a length of the turn-on period of each light source and turn-on reference timing that is start timing of the turn-on period as light source driving conditions; correction means correcting the light source driving conditions to reduce the brightnesses of at least part of the light sources so that power consumption of a power source at all of the turn-on reference timing is equal to or lower than a threshold if a maximum value of the power consumption of the power source at the turn-on reference timing of each light source exceeds a
