Gamma correction device and gamma correction method for liquid crystal display device

A gamma correction device for a liquid crystal display device, comprising:

• a storage device which stores gamma correction data corresponding to chiral directions of liquid crystal display panels;
• a chiral direction data acquisition circuit which acquires chirality data on a chiral direction of a liquid crystal display panel arranged in the liquid crystal display device;
• a control circuit, connected to the chiral direction data acquisition circuit, which sets a gamma correction datum adapted to the chiral direction of the liquid crystal display panel arranged in the liquid crystal display device selectively from the stored gamma correction data based on the acquired chirality data;
• and
• a gamma correction circuit which performs a gamma correction process on image signals provided to the liquid crystal display panel using the set gamma correction datum.
