Description
図1に、本実施の形態に係る液晶表示装置のソース配線電位の変化を示す。図2に、本実施の形態に係る液晶表示装置のブロック図を示す。まず、図2を用いて、本実施の形態に係る液晶表示装置の構成を説明する。なお、本実施の形態に係る液晶表示装置には、一般的なアクティブマトリクス型TFT液晶表示装置の構成を用いることができる。
一般的な液晶表示装置では、ゲート配線の片方側にゲートドライバを設けて、ゲート配線を駆動している。そのため、ゲート配線の入力側近傍ではゲート信号の波形は急峻となるが、入力側から遠くなるに従いゲート配線の抵抗と寄生容量によってゲート信号の波形がなまる。ゲート配線の両側にゲートドライバを設けて、ゲート配線の両側から駆動する液晶表示装置でも、ゲート配線の中心付近ではゲート信号の波形が入力側近傍に比べてなまる。
