一方、保護膜180は窒化ケイ素または酸化ケイ素などの無機絶縁物質で形成することもできる。
液晶層3に含まれている液晶分子は、画素電極190と共通電極270の間に電界が印加されない状態でその方向子が下部基板110と上部基板210に対して垂直をなすように配向され、負の誘電率異方性を有する。液晶表示装置は、このような基本パネル両側に偏光板、バックライト、補償板などの要素を設けて形成される。この時、偏光板は基本パネル両側に各々1つずつ配置され、その透過軸はゲート線121に対して平行であるか垂直をなすように配置する。
第4実施例による液晶表示装置の配置図は、発明の特徴において第2実施例による液晶表示装置の配置図と然程差がないので省略する。
