发明名称 LIQUID CRYSTAL DISPLAY
摘要 <P>PROBLEM TO BE SOLVED: To provide a liquid crystal display having high response speed and excellent visual field angle characteristics and display quality. <P>SOLUTION: Optical compensation elements 40A and 40B have first retardation plates 43A and 43B and second retardation plates 44A and 44B having retardation in a front direction, respectively. When a value obtained by specifying a retardation amount &Delta;n&times;d to light of each wavelength by retardation amount &Delta;n<SB>&lambda;</SB>&times;d to light of a prescribed wavelength is defined as &Delta;n/&Delta;n<SB>&lambda;</SB>, a specified value &Delta;n/&Delta;n<SB>&lambda;</SB>to light having a wavelength shorter than the prescribed wavelength in the first retardation plate is smaller than the specified value &Delta;n/&Delta;n<SB>&lambda;</SB>in a liquid crystal layer and a specified value &Delta;n/&Delta;n<SB>&lambda;</SB>in the second retardation plate is larger than the specified value &Delta;n/&Delta;n<SB>&lambda;</SB>in the liquid crystal layer. <P>COPYRIGHT: (C)2005,JPO&NCIPI
