Abstract: According to an aspect, a liquid-crystal display device includes: a liquid crystal layer including a pixel; a driving circuit unit for applying a driving voltage to the pixel; a status detection unit that detects a response speed of the liquid crystal layer; and a control unit that controls a gradation of the pixel by controlling the driving voltage. The control unit switches between a first mode and a second mode based on a detection result from the status detection unit. In the first mode, the control unit uses each of a predetermined number of voltage values from a minimum voltage value to a maximum voltage as a voltage value of the driving voltage corresponding to a gradation value. In the second mode, the control unit uses part of the predetermined number of voltage values as a voltage value of the driving voltage for overdrive.

Abstract: According to an aspect, a liquid-crystal display device includes: a liquid crystal layer; and a control unit that controls a display operation. The control unit performs a first display control mode when a response speed of the liquid crystal layer is equal to or higher than a predetermined speed and performs a second display control mode when the response speed of the liquid crystal layer is lower than the predetermined speed. In the first display control mode, the control unit executes a display control at a first frame rate with which a number of frames per unit time is equal to a predetermined number. In the second display control mode, the control unit executes a display control at a second frame rate obtained by dividing the number of frames at the first frame rate by an integer equal to or larger than 2.
