Abstract

A liquid crystal display element comprising a liquid crystal panel which comprises a pair of substrates and liquid crystal material sealed between the pair of substrates and in which pixel electrode parts of pixel electrodes and common electrode parts of common electrodes are alternately formed on a plane of one of the pair of substrates to change alignment of liquid crystal molecules by generating a horizontal (X) electric field in the plane, wherein at least one of the pixel electrode parts and the common electrode parts has a tapered section with respect to a horizontal (X) electric field direction and are transparent. The horizontal (X) electric field causes improved display characteristics, aperture ratio and response speed.
