Abstract

　本発明の目的は、斜め方向から観察したときの視野角、黒表示の再現性や鮮明性等の視認性、正面コントラストが改善されたＩＰＳモード型液晶表示装置を提供することにある。 本発明の目的は、第１偏光子と、第１基板と、液晶層と、第２基板とがこの順に配置され、第１偏光子と第１基板の間に第１位相差層と第２位相差層が配置されてなるＩＰＳモード型液晶表示装置であって、第１位相差層が負の二軸性であり、第２位相差層のレターデーションＲｏ、Ｒｔｈが０≦Ｒｏ≦５０ｎｍ、且つ５０≦Ｒｔｈ≦３００ｎｍであり、第１偏光子の吸収軸と黒表示時の液晶層の遅相軸方向が直交しており、第１位相差層がより第１偏光子側に近い場合は、第１位相差層の面内の遅相軸と第１偏光子の吸収軸が平行であり、第２位相差層がより第１偏光子側に近い場合は、第１位相差層の面内の遅相軸と第１偏光子の吸収軸が直交であることを特徴とする液晶表示装置によって達成された。
