<P>PROBLEM TO BE SOLVED: To suppress loose black color images in the oblique direction when using a circular polarizer. <P>SOLUTION: Each of the upper and lower circular polarizers provided in the liquid crystal display of this invention has 1/4 wavelength plates 16, 26 and linear polarizer plates 17, 27 respectively, and a birefringent element 28 is formed between the 1/4 wavelength plate 26 and the linear polarizer plate 27 constituting one of the circular polarizers. Further, nz>nx or nz>ny is satisfied when nx and ny represent the refractive indexes of this birefringent element 28 in the azimuth perpendicularly crossing each other in its plane, and nz the refractive index in its thickness direction. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
