Description
前記第1の基板は、ロール状のプラスチックフィルム基板であり、
前記第1の基板を第1の基板送り出し部から送り出して搬送し、第1の基板巻き取り部に巻き取るロール・ツー・ロール工程において、
前記第1の基板上に遮光層を形成する工程と、着色層を形成する工程と、共通電極を形成する工程と、前記第1の基板の少なくとも一方には、片面または両面にバリア膜を形成する工程を有し、
前記第2の基板は、予め能動素子が形成されたガラス基板が、プラスチックフィルム基板上に貼合された基板であり、
前記第2の基板を第2の基板送り出し部から送り出して搬送し、第2の基板巻き取り部に巻き取るロール・ツー・ロール工程において、
前記第2の基板のガラス基板上に能動素子を形成する工程と、前記ガラス基板をプラスチックフィルム基板上に貼合する工程と、前記第2の基板の少なくとも一方には、片面または両面にバリア膜を形成する工程を有し、
前記第1のロール・ツー・ロール工程と前記第2のロール・ツー・ロール工程において、
前記第1の基板と前記第2の基板の貼合面にそれぞれ配向膜を形成する工程と、
ODFプロセスによるシール剤描画工程と、液晶充填工程と、描画された前記シール剤を介した貼り合せ工程と、前記シール剤を硬化させる工程とを有することを特徴とする液晶表示装置の製造方法である。
(第1の実施の形態)
この第1の実施の形態の液晶表示装置を、図1及び図2に基づいて説明する。図1は液晶表示装置の概略構成図、図2は第2の基板のプラスチックフィルム基板の概略構成図である。
O=12〜18 (典型値17)
N=0〜24(典型値12)となる。
図3は第2の実施の形態の液晶表示装置の概略構成図である。この第2の実施の形態は、第1の実施の形態と同じ構成は同じ符号を付して説明を省略する。この第2の実施の形態では、ギャップ保持材15は、図3に示すように、球状スペーサ15bを用いている。この球状スペーサ15bは、一部が配向膜12に接して形成され、他部が配向膜13に接して形成されているが、一部の位置は第1の基板10a側の遮光層領域に形成され、他部の位置は第2の基板11b側の遮能動素子領域に形成されている。
図4は第3の実施の形態の液晶表示装置の概略構成図である。この第3の実施の形態は、第1の実施の形態と同じ構成は同じ符号を付して説明を省略する。この第3の実施の形態では、第1の基板10aと第2の基板11bは、貼合面と異なる面に偏光層20,21を有しており、液晶表示装置を通るバックライト光の透過制御を可能にしている。
図5は第4の実施の形態の液晶表示装置の概略構成図である。この第4の実施の形態は、第1の実施の形態と同じ構成は同じ符号を付して説明を省略する。この第4の実施の形態では、第2の基板11が、プラスチックフィルム基板11b上に能動素子17を直接形成された基板であり、能動素子17を直接形成することで、さらに軽量、薄型で、割れにくくなる。
図6は第5の実施の形態の液晶表示装置の概略構成図である。この第5の実施の形態は、第1の実施の形態と同じ構成は同じ符号を付して説明を省略する。この第5の実施の形態では、第1の基板10a側の遮光層22が、活性層17a上方に配置され、目視方向からの外光が液晶表示装置に入射する際、活性層17aへ入射光が当たらなくなるため、活性層17aの誤動作や特性変化が起きにくくなる。
この実施の形態の液晶表示装置の製造方法及び液晶表示装置の製造装置を、図7乃至図9に基づいて説明する。図7は第1の基板製造装置の概略構成図、図8は第2の基板製造装置の概略構成図、図9は第1の基板と第2の基板の貼合装置の概略構成図である。
