发明名称 LIQUID CRYSTAL DEVICE AND PROJECTION DISPLAY DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a liquid crystal device ensuring a high contrast display. <P>SOLUTION: The liquid crystal device is constructed by interposing a liquid crystal layer between a pair of substrates 10, 20, and disposing a first optical compensation plate 70 and a second optical compensation plate 80 each having uniaxial negative anisotropy of a refractive index on the outer surface side of the substrate 10. The liquid crystal layer interposed between the substrates consists of a twisted nematic liquid crystal having >68&deg; and <90&deg; twist angle. <P>COPYRIGHT: (C)2005,JPO&NCIPI
