Abstract

The object is to make alignment of passive, vertically aligned liquid crystal displays more uniform by reducing alignment disorder when a voltage is applied and to improve the display quality. A liquid crystal display element comprises a first electrode (122) disposed to display a prescribed display pattern in a display area, a second electrode (141) opposed to the first electrode, and a liquid crystal layer provided between the first electrode and the second electrode and exhibiting vertical alignment of liquid crystal molecules in the voltage-off state, wherein either one of the first electrode and the second electrode is provided with a plurality of regularly disposed L-shaped slits (21), and the L-shaped slits (21) are formed so that at least within an area where the first electrode and the second electrode overlap each other, the electrode provided with the slits is divided into a plurality of rectangular electrode regions each having connection portions at three corners for connection to adjacent electrode regions.

Description

technical field

[0001] The present invention relates to a liquid crystal display element in which the initial alignment of liquid crystal is in a vertical direction, and particularly relates to a liquid crystal display element capable of reducing alignment disorder. Background technique

[0002] As a liquid crystal display element, there is a liquid crystal display element in which the orientation (initial orientation) of the liquid crystal molecules in the liquid crystal layer when no voltage is applied is a vertical orientation substantially perpendicular to the substrate surface. The above-mentioned liquid crystal display element is called a VA (Vertical Alignment: vertical alignment) type liquid crystal display element. In a VA-type liquid crystal display element, a liquid crystal having a negative dielectric anisotropy is used. Furthermore, by applying a voltage to the liquid crystal layer, the liquid crystal (liquid crystal molecules) can be brought into a state close...
