Description
前記後基板1の内面の第1と第2の電極4,5のうち、液晶層3側に設けられ、前記TFT6のソース電極10に接続された櫛形導電膜5aからなる第2の電極5と、前記前基板2の内面に設けられた一枚膜状の導電膜からなる第3の電極15との間には、液晶表示素子の起動時に、前記液晶層3の層厚方向に、前記液晶分子3aを前記スプレイ配向からベンド配向に転移させるための予め定めた値の縦電界と、前記起動後に、前記液晶層3の層厚方向に、画像データに対応した駆動電界を生成される。また、前記後基板1の内面の第1と第2の電極4,5間には、前記起動時に、前記配向転移電界の方向に対して交差し、基板面と実質的に平行な方向の、前記液晶分子3aを前記基板1,2間において捩れ配列させるための横電界を生成される。
Claims (4)
