<P>PROBLEM TO BE SOLVED: To provide a twisted nematic (TN) mode liquid crystal display element provided with characteristics such as an excellent black level, high contrast, a wide viewing angle, excellent steepness and the like. <P>SOLUTION: The liquid crystal display element has: a driving cell having upper side and lower side substrates equipped with electrodes, and a liquid crystal layer held in between and comprising liquid crystal molecules twist-aligned and having a helical structure in the state with no electric field; a compensating means disposed on a surface of one substrate of the driving cell and including upper side and lower side substrates, and a liquid crystal layer held in between and comprising liquid crystal molecules twist-aligned and having a helical structure, wherein, with respect to the liquid crystal layer, a twist direction of the helical structure is opposite to that of the helical structure in the driving cell, and the orientation direction of a liquid crystal molecule at the center of the liquid crystal layer and that in the driving cell vertically intersect with each other at right angles in surfaces of the upper side and lower side substrates; and two polarizing plates disposed on both sides of a structural body including the driving cell and the compensating means respectively in crossed Nicols, wherein both directions of transmission axes or absorption axes thereof are at 45° angle to the orientation direction of the liquid crystal molecule at the center of the liquid crystal layer of the driving cell in crossed Nicols disposition. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
