Abstract

An object of the present invention is to realize a liquid crystal display device of a field sequential system which is capable of preventing occurrence of color shift and flicker. One frame period is divided into a plurality of fields, the number of which is greater than the number of lighting patterns. Provided are a liquid crystal state value acquiring unit () configured to obtain a liquid crystal state value at an end time of a display field based on an input gradation value in the display field and a liquid crystal state value at an end time of a previous field (one field before the display field) (a gradation value corresponding to an aligned state of liquid crystal molecules), and an application gradation value acquiring unit () configured to obtain an application gradation value in the display field by correcting an input gradation value in the display field based on a liquid crystal state value at the end time of the previous field. The application gradation value acquiring unit () obtains an application gradation value such that display luminance in each field becomes display luminance corresponding to the input gradation value.
