Abstract
A gamma correction device for a liquid crystal display device including LCD panels. The gamma correction device includes a storage device for storing gamma correction data corresponding to chiral directions of LCD panels. A chiral direction data acquisition circuit acquires chirality data on the chiral direction of a LCD panel arranged in the liquid crystal display device. A control circuit sets a gamma correction datum adapted to the chiral directions of the LCD panel arranged in the liquid crystal display device selectively from the stored gamma correction data based on the acquired chirality data. A gamma correction circuit performs a gamma correction process on image signals provided to the LCD panel using the set gamma correction datum.
