发明名称 LIQUID CRYSTAL DISPLAY DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide an inexpensive and lightweight liquid crystal display device capable of stably providing such excellent display quality that background colors are nearly eliminated. <P>SOLUTION: The direction 5a of front orientation processing and the direction 7a of rear orientation processing applied to a front orientation film and a rear orientation film of a liquid crystal cell C are at -35&plusmn;5&deg; and 35&plusmn;5&deg; to the horizontal direction (h) of a display screen, and consequently liquid crystal molecules are subjected to twist alignment over 250&plusmn;10&deg; from the rear to the front, so that &Delta;n d is 770 to 850 nm. On the front side of the liquid crystal cell C, a 1st retardation plate 8 and a 2nd retardation plate 9 of 400 to 450 nm in retardation are layered in such arrangement that slow axes 8a and 9a are at 65&plusmn;5&deg; and 20&plusmn;5&deg; respectively to the horizontal direction (h), and a front polarizing plate 10 is layered thereupon in arrangement that an axis 10a of absorption is at 95&plusmn;5&deg; to the horizontal direction. On the rear side of the liquid crystal cell C, a rear polarizing plate 11 is layered in such arrangement that an axis of absorption is at 85&plusmn;5&deg; to the horizontal direction (h). <P>COPYRIGHT: (C)2005,JPO&NCIPI
