Description
まず、液晶表示装置の第1、2基板を製作する(S100)。
前記液晶表示装置の第2基板はカラーフィルタを有し、前記第1基板には薄膜トランジスタを含むマトリックス形態のアレイ素子が形成される。
続いて、ラビング装置を用いて、焼成処理された配向膜の表面を一定の方向に擦る配向膜ラビング工程(S140)を行う。
次に、前記第1、2基板を対向合着するが、与えられたマージンから外れたら光が漏れるので、通常数マイクロメートル程度の精密度が要求される(S160)。
ここで、液晶の物理的特性は分子配列状態によって変わり、よって、電界などの外力に対する応答にも差ができる。
まず、配向膜は、高分子薄膜を塗布し、配向膜を一定の方向に配列する工程で形成される。前記配向膜には、一般に、ポリイミド(polyimide)系列の有機物質が使われ、前記配向膜を配列する方法としては、主にラビング方法が用いられている。
図3A乃至図3Gは、本発明に係る一実施の形態として、横電界方式の液晶表示装置の製造工程を順次示す図面である。
まず、液晶表示装置の上、下基板を製作する(S200)。そして、パターンらが形成された基板上の異物質を除去するために洗浄工程(S210)を行い、配向膜印刷装置を用いて、基板の上面に配向膜原料液のポリイミド(PolyImide:PI)などを印刷する配向膜印刷工程(S220)を行う。
図5Aに図示されたように、前記基板上に形成されている配向膜は1次配向処理されて形成される。前記1次配向処理は、ポリイミドのような配向物質からなる前記配向膜上にベルベット、レーヨン、ナイロンなどを巻いたラビング布を用いて、前記配向膜を一定の方向にこすることにより、配向方向を形成するラビング方法で行われる。このとき、基板上に段差が0.1μm以上の電極部周辺をラビングすると、前記段差部によりラビング布が配向膜に届かなく配向が行われなかったり、ラビング布が段差を通過しながらラビング布が乱れるようになって、配向整列度が不均一になり、光漏れが発生する。
