PURPOSE:To provide a liquid crystal display element having a high scattering characteristic, low driving voltage, excellent gradation characteristic and wide visual field angle characteristic with high productivity. CONSTITUTION:A nematic liquid crystal layer 20 having positive dielectric anisotropy is clamped between two sheets of substrates 11 and 12 provided with electrodes 13, 14. The twist angle 4 of the liquid crystal is + or -theta+180 deg. or + or -theta-180 deg. when psi is + or -theta in the state of not a voltage to the liquid crystal layer when the intersection angle of the liquid crystal molecule arrangement directions on two sheets of the substrates is theta(0 deg.<=theta<=90 deg.) and the cell twist angle determined to cause uniform twist arrangement on the surfaces of two sheets of the substrates is psi. The twist angle omega of the liquid crystal when psi is + or -(theta-180 deg.) is + or -theta. A conductor part 13a (14a) and non-conductor part 13b (14b) are formed in fine region unit of <=30mum on the electrode of each one picture element. The conductor part 13a (14a) of the one electrode and the non-conductor part 13b (14b) of the other electrode are arranged to face each other between both substrates. Both substrates have low-pretilt angle oriented films 15, 16 of <=2.5 deg. and the pretilt angle difference of both substrates is <=0.3 deg.. |
