PURPOSE: To extend allowable ranges of the voltage, the temperature, and the cell thickness to increase the number of displayable picture elements, by using a specific optically active resin as materials of an oriented film in the storage type liquid crystal display element using the helical structure liquid crystal.

CONSTITUTION: A liquid crystal 4, which has a helical structure of ≤5μ helical pitch, and oriented films 3a and 3b consisting of an optically active resin which induces the helical direction opposite to that of the liquid crystal 4 in the liquid crystal 4 are held between a pair of electrode substrates 1a and 1b either of which is transparent at least, thus producing a liquid crystal display element. If the helical pitch exceeds 5μ, a sufficient contrast cannot be obtained in the display element where the interval of electrodes is about 5W30μ, and the storage time is shortened, and the display element is inferior in practicality. The simple or a mixture of a cholestric liquid crystal is used. A polyamino acid resin is used desirably as the optically active resin constituting oriented films. The relaxation time is made longer to obtain a liquid crystal display element where the display characteristic, specially, the wirting and erasing operation characteristic is improved.
