Description
本発明に係る実施の形態1の画像表示装置として、アクティブ駆動方式の反射型液晶表示装置を例に挙げて説明する。反射型液晶表示装置は、液晶(表示素材に相当)を、反射電極を有する基板と、対向電極を有する基板とで狭んで構成される。反射型液晶表示装置とは、反射電極によって、外光を液晶層側に反射させて、画像を表示するものである。本発明では、さらに反射電極表面に凹凸形状を形成し、外光を散乱させることで、画像表示装置の視認性を向上させている。
本発明に係る実施の形態2の画像表示装置として、反射型液晶表示装置を例に挙げて説明する。本実施の形態2に係る反射型液晶表示装置は、後述するように、信号線3および絶縁膜2のパターン形状以外は、実施の形態1で述べた反射型液晶表示装置の構成と同一であるため、重畳する説明は割愛する。なお、図中の同一符号は同一または相当部分を指す。
