Abstract

본 발명은 강유전성 액정표시장치의 액정주입방법에 관한 것으로, 강유전성 액정표시장치의 액정주입시 결합이 없는 균일한 배향상태를 얻기 위한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal injection method of a ferroelectric liquid crystal display device, and to obtain a uniform alignment state without bonding during liquid crystal injection of a ferroelectric liquid crystal display device.

본 발명은 액정패널과, 상기 액정패널의 상, 하부에 편광방향이 서로 수직되게 형성된 편광자와, 상기액정패널에 전원을 인가하기 위한 전원인가부로 구성된 액정셀을 강유전성 액정이 담겨 있는 용기를 내부에 포함되어 있는 진공챔버내에 장착하는 공정과, 상기 진공챔버 내부를 진공으로 만드는 공정, 상기 액정셀을 상기 진공 챔버내의 액정이 담겨 있는 용기에 접촉시켜 상기 액정이 담겨 있는 용기안의 강유전성액정에 상기 액정셀면을 접촉시키거나 침전시키는 공정, 상기 강유전성액정이 스멕틱 A상태에서 스멕틱^*C상태로의 상전이가 일어나는 시점에서 상기 전원인가부를 통해 교류전원을 인가하는 공정으로 이루어지는 강유전성 액정표시장치의 액정주입방법을 제공한다.The present invention includes a liquid crystal panel comprising a liquid crystal panel, a polarizer formed on the upper and lower sides of the liquid crystal panel perpendicular to each other, and a liquid crystal cell including a power supply unit for applying power to the liquid crystal panel. Mounting in an included vacuum chamber, making the inside of the vacuum chamber into a vacuum, and contacting the liquid crystal cell with a container containing liquid crystal in the vacuum chamber so that the liquid crystal cell surface is in a ferroelectric liquid crystal in the container containing the liquid crystal. Contacting or precipitating the liquid crystal, and the ferroelectric liquid crystal is a liquid crystal injection method of the ferroelectric liquid crystal display device comprising the step of applying an AC power through the power supply when the phase transition from the Smectic A state to Smectic ^* C state To provide.
