Problems solved by technology

If a DC voltage is applied to prevent the contrast from falling, ions in the liquid crystal layer will accumulate on the alignment layer, resulting in afterimage phenomenon
That is, there is a problem that the previous display image remains dimly even after the previous display state has shifted to the next display state

Abstract

A ferroelectric liquid crystal display, comprising an upper substrate and a lower substrate, the configurations of which are separated by a predetermined distance; face-to-face electrode layers respectively formed on the upper substrate and the lower substrate; electrode layers respectively formed on the electrode layers orientation layers, and the corresponding orientation layers are processed by rubbing along a first rubbing direction and rubbing along a second rubbing direction, the first rubbing direction and the second rubbing direction intersect at a predetermined angle; Shape structure of the liquid crystal layer of ferroelectric liquid crystal. Due to the ferroelectric liquid crystal display and its manufacturing method, the ferroelectric liquid crystal having a bookshelf structure can be stably distorted through orientation treatment, thereby preventing afterimage phenomenon, and obtaining lower threshold voltage and bistable state.

Description

technical field [0001] The present invention relates to a ferroelectric liquid crystal display and a manufacturing method thereof, and more particularly, to a ferroelectric liquid crystal display having a bistable state and high contrast by using a ferroelectric liquid crystal having a bookshelf-shaped structure. Background technique [0002] A widely used ferroelectric liquid crystal display adopts a chiral smectic C (smectic-C, SmC*) liquid crystal material with a chevron structure. [0003] The ferroelectric liquid crystal display using this liquid crystal material is manufactured according to such a process, that is, if a suitable liquid crystal is injected into the ferroelectric liquid crystal display, and then the temperature is lowered, the ferroelectric liquid crystal will thus transform into a chiral nematic phase (nematic phase). N*), that is, the smectic-A phase with a lamellar structure perpendicular to the rubbing direction, which th...
