REFLECTION TYPE LIQUID CRYSTAL DISPLAY ELEMENT

摘要

PURPOSE: To obtain a reflection type liquid crystal display element which realizes a bright white display, high contrast and achromatic white-and-black display by controlling the angle between the referential line and the direction of an absorption axis of a polarizing film and controlling the angle between the referential line and the direction of a slow phase axis of an optical compensation film to each specified range. CONSTITUTION: A twist angle in a nematic liquid crystal between a pair of substrates is specified to 45deg. to 90deg.. The direction of twist of the nematic liquid crystal from one substrate to the other substrate observed from one substrate side is defined as positive. The angle &phgr;P between the referential line 20 and the direction of the absorption axis 24 of the polarizing film, the angle &phgr;F1 between the referential line 20 and the direction of the slow phase axis 23a of the optical compensation film in the polarizing film side, and the angle &phgr;F2 between the referential line 20 and the direction of the slow phase axis 23b of the optical compensation film in the liquid crystal cell side are controlled to 75deg. to 195deg. of &phgr;P, 95deg. to 115deg. of &phgr;P-&phgr;F1 and 155deg. to 175deg. of &phgr;P-&phgr;F2.
