Abstract
【解決手段】本発明の液晶表示装置は、画素領域を反射領域と透過領域に区切り、透過領域に電界誘導窓が形成され、画素領域に画素電極が形成され、反射領域と前記透過領域との境界に所定の段差部が形成された第1基板と、第1基板と対向されて配置され、電界誘導窓から所定距離に置かれ誘電体突起が形成された第2基板と、第1基板と第2基板との間に挿入された液晶層を含む。
【選択図】 図3
Description
図3及び図4で、本発明のVAモード液晶表示装置は、ゲートライン(107)とデータライン(109)によって画素領域が定義され、前記画素領域を光を反射させる反射領域(r)と光を透過させる透過領域(t)に区切り、前記透過領域(t)に電界誘導窓(114)が形成され、前記画素領域に画素電極(113)が形成され、そして前記反射領域(r)と前記透過領域(t)との境界に所定の段差部が形成された第1基板(101)と、前記第1基板(101)と対向されて配置され、前記電界誘導窓(114)から所定距離に間隔を置いた誘電体突起(110)が形成された第2基板(102)と、前記第1及び第2基板(101、102)の間に挿入された液晶層(120)を具備する。
δ= Δn ・d
によって得られる。
δは液晶の位相差値で、Δnは液晶の屈折率で、dはセルギャップである。これによって、光の反射を利用する反射モードと光の透過を利用する透過モード間には光効率の差が発生するようになる。このような光効率の差を減らすために、透過領域(t)のセルギャップ(d1)を反射領域(r)のセルギャップ(d2)より大きくして、これに従って液晶層(320)の位相差値を一定に維持することができる。
図5に図示されたように、画素領域が反射領域(r)と透過領域(t)とに区画される。この時、前記画素領域には一つの透過領域(t)と少なくとも2個以上の反射領域(r)が存在することができる。
