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

摘要

broadcast receiving apparatus , a pair of the twist-oriented by 90 between the substrates , a liquid crystal layer sandwiched (1) and , sandwiched between the liquid crystal cell , the absorption axis (12a, 16a) the alignment treatment direction of the substrate (7a, 8a) of the first and second polarizing plates disposed in crossed by 45 to the (12 , 16) , comprises the polarizing layers ( 12,16 ) and the cell (1) liquid crystal display device having a viewing angle compensation plates ( 19,22 ) disposed respectively in between . And the refractive index difference in the vertical plane of the substrate surface of a cell of the optical layer is present between the polarizing layer , the total value of retardation in the thickness direction defined by the value of the product of the layer thickness is saturated in the liquid crystal layer when a voltage is applied , is set to a value that substantially offset the liquid crystal layer thickness direction retardation .
