摘要： A liquid crystal display includes: a light source section including light-emission subsections controlled separately from one another; a liquid crystal display panel modulating, based on an input picture signal, light emitted from each light-emission subsection to display pictures; and a display control section including a partitioning-drive processing section which generates a light-emission pattern signal representing a two-dimensional pattern formed from lighting light-emission subsections and a partitioning-drive picture signal based on the input picture signal, the display control section performing a light-emission drive on each light-emission subsection based on the light-emission pattern signal and performing a display-drive on the liquid crystal display panel based on the partitioning-drive picture signal. The partitioning-drive processing section determines, based on the input picture signal, a barycentric position in a partitioned picture corresponding to each light-emission subsection, and generates the light-emission pattern signal and the partitioning-drive picture signal based on the barycentric position.
