Description
なお、実施例を説明するための全図において、同一機能を有するものは、同一符号を付け、その繰り返しの説明は省略する。
図1は、液晶表示パネルを観察者側からみた模式平面図である。図2は、図1のA−A’線における模式断面図である。図3は、液晶表示パネルのTFT基板における表示領域の1画素の構成例を示す模式平面図である。図4は、図3のB−B’線における模式断面図である。図5は、図3のC−C’線における模式断面図である。
図7は、図6に示した構成と類似した構成の液晶表示装置の一構成例を示す模式図である。図8は、図6に示した構成の液晶表示装置と図7に示した構成の液晶表示装置との違いを説明するための波形図である。なお、図7において、図6と異なる点は、ドライバ電源供給配線GVLとコモンセンシング配線Csenの配置の順番であり、図7に示した例では、コモンセンシング配線Csenが一番外側にくるように配置されている。
