Abstract

　複数の画素電極を有するアクティブマトリクス基板（２０）と、共通電極（３３）を有する対向基板（３０）と、両基板の間に設けられる液晶層（４０）とを備え、複数の画素（１０）により構成されるＣＰＡ方式の液晶表示装置であって、画素電極（２３）と共通電極（３３）とは互いに一定の間隔をあけて配置され、各画素（１０）は、反射モードの表示を行う反射表示領域（Ｒ）と、透過モードの表示を行う透過表示領域（Ｔ）とを有し、反射表示領域（Ｒ）には、反射表示領域（Ｒ）における液晶層（４０）の一部の厚さ（ｄ２）を透過表示領域（Ｔ）における液晶層（４０）の厚さ（ｄ１）よりも小さくするとともに、液晶層（４０）の液晶分子の配向方向を制御する配向制御部（４）が設けられている。これにより、透過表示領域および反射表示領域を備えた、ＣＰＡ方式の液晶表示装置において、透過モードおよび反射モードにおける表示品位の劣化を防ぐとともに、両モードにおける応答速度を略均一化する。
