发明名称 LIQUID CRYSTAL PANEL AND LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME
摘要 <P>PROBLEM TO BE SOLVED: To provide a liquid crystal panel with which an excellent balance between contrast and viewing angle characteristics is achieved. <P>SOLUTION: The liquid crystal panel has: a first polarizer; a first optical compensation layer containing a resin with an absolute value of its photoelastic coefficient being 2&times;10<SP>-11</SP>m<SP>2</SP>/N or less and with a relation expressed by an inequality nx>ny=nz; a second optical compensation layer with a relation expressed by an inequality nx=ny>nz; a liquid crystal cell; a third optical compensation layer containing a resin with an absolute value of its photoelastic coefficient being 2&times;10<SP>-11</SP>m<SP>2</SP>/N or less and with a relation expressed by the inequality nx>ny=nz; and a second polarizer, sequentially toward the viewer's side in this order, wherein the sum total &Sigma;Rth<SB>1 to n</SB>of retardation values in the thickness direction of all the optical compensation layers and the retardation value Rthc in the thickness direction of the liquid crystal cell satisfy an inequality (1) -50 nm<(&Sigma;Rth<SB>1 to n</SB>-Rthc)<150 nm. <P>COPYRIGHT: (C)2007,JPO&INPIT
