LIQUID CRYSTAL DISPLAY DEVICE WITH IMPROVED VIEWING ANGLE AND TELEVISION SET WITH SUCH A DEVICE

摘要

: A broadcasting receiving apparatus includes a liquid crystal display device including a liquid crystal cell (1) in which a liquid crystal layer (10) that is twist-aligned at 90° and sandwiched between a pair of substrates (2, 3), first and second polarizing layers (12, 16) arranged to sandwich the cell therebetween so that their absorption axes (12a, 16a) are set in parallel with directions crossing aligning treatment directions (7a, 8a) of the substrates at 45°, and viewing angle compensating plates (19, 22) respectively arranged between the polarizing layers (12, 16) and the cell (1). A total value of retardations in a thickness direction, defined as a value of a product of a phase difference within a plane perpendicular to substrate surfaces of the cell and a layer thickness, of optical layers present between the polarizing layers is set to a value that substantially cancels out a retardation in a liquid crystal layer thickness direction when a saturation voltage is applied to the liquid crystal layer.
