Abstract
A liquid crystal display device of a time division driving system, capable of preventing an occurrence of a color shift without causing flickering or image sticking, is achieved. The liquid crystal display device includes: a stable arrival gradation data acquisition unit () configured to acquire stable arrival gradation data indicating an arrival gradation estimation value at a start timing of each field of the last frame, in a case where a virtual display process of three or more frames is performed based on input gradation data for one frame; and an input gradation data compensation unit configured to acquire writing gradation data by compensating the input gradation data based on the stable arrival gradation data. The stable arrival gradation data acquisition unit () includes a plurality of arrival gradation value estimation circuits () each being configured to perform an arrival gradation value estimation process (a process for acquiring an arrival gradation estimation value at the start timing of a next field, based on input gradation data for an object field and an arrival gradation estimation value at the start timing of the object field).
