Abstract
A liquid crystal display device of one aspect of the present invention includes a liquid crystal display unit that includes a liquid crystal layer which exhibits vertical alignment and plural picture elements, and a control unit that controls a voltage which is supplied to the liquid crystal display unit. The control unit performs display by sequentially applying a first voltage that corresponds to a larger gradation number than an original gradation number and a second voltage that corresponds to zero gradation respectively in plural subframe periods that result from division of one frame period of an image signal in a case where the original gradation number of the input image signal is a low gradation number that is less than a prescribed threshold value, performs display by applying the second voltage in the one frame period in a case where the original gradation number is the zero gradation, and performs display by applying a third voltage that corresponds to the original gradation number in the one frame period in a case where the original gradation number is a high gradation number that is equivalent to or more than the threshold value.
