A liquid crystal display device includes a display panel and a viewing
angle control panel. The viewing angle control panel includes a pair of
substrates, a liquid crystal layer interposed between the pair of
substrates, and a pair of electrodes for applying an electric field to
the liquid crystal layer. The liquid crystal layer is composed from
hybrid-aligned liquid crystal molecules. The viewing angle of the display
panel is controlled by changing an alignment state of the hybrid-aligned
liquid crystal molecules in the liquid crystal layer by voltage applied
by the electrodes.
