本実施形態に係る液晶表示装置1の製造方法は、例えば以下のプロセスを含む。製造装置は、画素基板(第1基板)70AのTFT基板71として透光性基板である、ガラス基板を用意する第1基板の準備工程を処理する。
評価例1乃至評価例3について、以下、評価した結果を説明する。これら評価例で、本発明は限定されるものではない。図22は、本実施形態に係る液晶表示部の評価例1において、画素の応答速度とディスクリネーションライン同士の平均間隔との関係を説明するための説明図である。隣り合うディスクリネーションラインdclの平均間隔lが無限大の電圧OFF時の基準応答時間Tfを1として、評価例1の副画素Vpixの開口幅、セル厚dを同一の条件とした場合における平均間隔lが2μm、3μm、5μm、10μm、20μm、100μmの基準応答時間に対する電圧OFF時応答時間τの相対値をシミュレーションした。図22は、シミュレーション結果を示している。図22に示すように、平均間隔lが10μm以下の場合、液晶表示装置1は、電圧OFF時応答時間τを早くすることができる。その結果、液晶表示装置1は、液晶の応答速度を早くすることができる。
次に、図24及び図25を参照して、本実施形態及び変形例で説明した液晶表示装置1の適用例について説明する。図24及び図25は、本実施形態に係る液晶表示装置を適用する電子機器の一例を示す図である。本実施形態に係る液晶表示装置1は、図24に示すカーナビゲーションシステム、テレビジョン装置、デジタルカメラ、ノート型パーソナルコンピュータ、図25に示す携帯電話等の携帯端末装置あるいはビデオカメラなどのあらゆる分野の電子機器に適用することが可能である。言い換えると、本実施形態に係る液晶表示装置1は、外部から入力された映像信号あるいは内部で生成した映像信号を、画像あるいは映像として表示するあらゆる分野の電子機器に適用することが可能である。電子機器は、液晶表示装置に映像信号を供給し、液晶表示装置の動作を制御する制御装置4(図1参照)を備える。
