Description
以下、この発明の実施の形態1を図面を参照しながら詳細に説明する。図1は、上述の互いに対向する一対の基板から構成される液晶パネルの一方の基板であるCF基板の平面模式図である。また本実施の形態では、他方の基板であるTFT基板は一般的なTN液晶モードに対応したTFT基板を採用しているので、特に詳細な説明はしない。図2は、図1の断面模式図であり、上記のように液晶パネルがTN液晶モードに対応した断面構造を有している。図3は本発明で使用する配向膜転写版の平面模式図であり、さらに図4は本発明での配向膜塗布状態を表す模式図である。
まず、図1に示す様に、CF基板1は、その表面が予め濡れ性(wettability)の低い領域2と、濡れ性の大きい領域3に区別されて作成される。すなわち本実施の形態では、CF基板1の表面を形成する際に、濡れ性の小さい領域2は、配向膜を塗布しない領域に対応して、また濡れ性の大きい領域3は、配向膜を塗布する領域に対応して形成される。なお、ここで言う基板表面の「濡れ性」とは、配向膜材料に対する「濡れ性」の大/小(良い/悪い)を意味する。
まず、配向膜を塗布する際に必要となる転写版の構成について説明する。図3に示すように配向膜を塗布する転写版10は、転写版下地11上に配向膜材料を塗る転写版凸部12で構成されている。転写版材料としてはポリブタジエンゴム等を用いる。転写版凸部12には配向膜13を付着させる領域と付着させない領域を区分する凹部は無く、一様なベタパターンである。
本実施の形態では、上記他方の基板であるTFT基板は一般的なIPS液晶モードに対応したTFT基板を採用しているので、特に詳細な説明はしない。その他、CF基板1の平面図(図1)や、配向膜転写版(図3)、配向膜塗布模工程(図4)などは、上述の実施の形態1と同様であるので、詳細な説明は省略する。
