摘要： Disclosed is a liquid crystal display device including: a VA-IPS mode liquid crystal display panel; a backlight unit incorporating a PWM dimming type light source; and a control unit that controls the liquid crystal display panel and the backlight unit, in which the control unit obtains response speed data of orientation change of liquid crystal molecules, and changes a duty factor of a PWM dimming signal according to the response speed data. In a case where the response speed of the liquid crystal molecules is relatively high, LEDs are driven with a relatively small duty factor. In a case where the response speed of the liquid crystal molecules is relatively low, the LEDs are driven with a relatively large duty factor, and black insertion is not performed. The liquid crystal display device prevents an image quality malfunction (multiple outlines).
