<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of improving contrast performance. <P>SOLUTION: In the liquid crystal display device, light is radiated to the back of a liquid crystal display part 1 from a light source 2, and an image is displayed in the liquid crystal display part 1 based on an image signal S. The liquid crystal display device, in which the liquid crystal display part 1 is divided into a plurality of pseudo regions A1-A9, includes: a plurality of auxiliary light sources 51-59 arranged in association with the respective regions; a luminance calculation part 6 calculating luminance of an image displayed in each of the regions A1-A9 for each of the regions based on the image signal S; and an auxiliary light source control part 7 controlling light emission quantity of each of the auxiliary light sources 51-59 based on the luminance obtained by the luminance calculation part 6. <P>COPYRIGHT: (C)2010,JPO&INPIT |
