Abstract

A display device includes an image display panel and a control device. The image display panel includes first sub-pixels, second sub-pixels, third sub-pixels, and fourth sub-pixels in which a specified sub-pixel column including the third sub-pixels and the fourth sub-pixels and at least one other sub-pixel column arranged next to the specified sub-pixel column are periodically arranged. The control device performs column inversion driving to apply a voltage having the same polarity to signal lines of a first specified sub-pixel column belonging to the specified sub-pixel columns and the other sub-pixel column adjacent to the first specified sub-pixel column, apply a voltage having the same polarity as the first specified sub-pixel column to one of the signal lines of a second specified sub-pixel column and a third specified sub-pixel column adjacent to the first specified sub-pixel column, and invert the polarities of the voltages to be applied at predetermined cycles.
