The first common electrode(1) is patterned on the lower substrate in a plane form. The insulated layer is located between the lower part of the first common electrode(1) and the first and second pixel electrodes(2,3). The first pixel electrode(2) is transversely patterned on a portion of the upper part of the insulated layer in a latticed form.

The liquid crystal layer, horizontally arranged, is located at the upper parts of the first and second pixel electrodes(2,3).

Abstract: 본발명은반투과형액정표시장치에필수적으로사용되는부착형위상지연필름을사용하지않고셀 내부의반사영역에전기장또는자기장을이용하여중합성액정조성물에배향성을형성하여패턴된내장형위장지연필름을사용한반투과형액정표시장지에관한것이다. 본발명은외부에부착형위상지연필름을사용하지않기때문에필름부착으로발생하는정전기발생및 이미지겹침현상등의문제가발생하지않는다. 본발명에따른위상지연필름의제조방법은전기장또는자기장을이용하여중합성액정조성물에배향성을형성시키기때문에배향제층을형성하는공정자체가없고, 결과적으로배향제층에러빙또는광배향하는공정자체를생략할수 있다. 따라서, 본발명의제조방법은종래부착형위상지연필름을사용하는경우에비해간소화된공정라인구축과매우빠른공정속도를구현할수 있으므로제조비용을절감할수 있다. 또한, 반사영역과투과영역이단일셀갭구조이고특히 IPS 모드는화소전극윗 부분을반사영역으로사용하기때문에현재사용되는반투과형제조공정을그대로사용할수 있는장점이있다.
