Liquid crystal display device and image display method thereof

摘要

A liquid crystal panel displays an image from image signals. A backlight device disposed on the back side of the liquid crystal panel, and divided into a plurality of regions. The backlight device is configured to allow light emitted from the light source of each of the regions to leak to adjacent regions. A light emission luminance calculator obtains a light emission luminance by using, as adjacent regions, a group of regions from the regions in the backlight device and at least two virtual regions provided respectively at opposite ends of the group of regions.
