PURPOSE: To obtain a liquid crystal display element having a stable shape with extremely small deformation, by constituting upper and lower electrode polarization substrates in such a way that the axes of the base films for the same are equal and are in parallel with the longitudinal direction of the element.

CONSTITUTION: This liquid crystal display device has an upper electrode polarization substrate 12 and a lower electrode polarization substrate 13 of which the axes 15a of the films are made in parallel with the longitudinal directin of the element as shown in (a). Therefore, a camber (deformation) is generated in the transverse direction thereof, but the max. (h) of the camber is ≤0.5mm and the camber of the element is virtually inconspicuous in appearance. In the constitution shown in (b), on the other hand, the axis 15a of the film of the substrate 13 is in parallel with the transverse direction of the element and therefore a camber is generated in the longitudinal direction and the max. (h) thereof is ≥1mm, thus the camber is conspicuous and is undesirable. Even if the substrates 12, 13 are formed by reversing the upper and lower side in the element shown in the above-described (a), the element having the smaller camber is obtainable.
