Abstract
【解決手段】液晶表示装置(1)のデータ信号生成部(140)は、液晶の配向を制御するためのデータ信号を生成する。複数のトランジスタ(T[M])は、ソースIC部(160)から出力されるデータ信号を、液晶表示パネル(100)の複数のデータ信号線(D[M])に時分割で供給する。ゲート信号線(171)は、複数のトランジスタ(T[M])の各々を制御する。変動抑制部(173)は、複数のトランジスタ(T[M])の何れかを制御するゲート信号線(171)に接続され、他のトランジスタ(T[M])がオン状態からオフ状態に変化する場合に発生するデータ信号の電位変動を、接続されたゲート信号線(171)のゲート信号に応じて抑制する。
