A liquid crystal display device includes: a liquid crystal display unit that displays, for each of frames, an image based on an input image signal; a drive unit that applies a voltage based on the input image signal to pixels of the liquid crystal display unit; and a control unit that controls an amplitude of the voltage applied to the pixels. The drive unit applies, in one of the frames, a voltage of the same polarity to the pixels connected to one of the source signal lines. The control unit includes: a temperature-information acquiring unit that acquires temperature information of the drive unit; and a filter unit that acquires high-frequency and low-frequency components of the input image signal in a substantial extending direction of the source signal lines. The control unit controls the amplitude of the applied voltage using the temperature information and an output value of the high-frequency component.
