To provide a display device capable of suppressing deterioration of image quality while suppressing increase in device scale.SOLUTION: A display device has a plurality of data drivers provided for every predetermined number of data lines among a plurality of data lines. Each of the plurality of data drivers receives a serialized video data signal from a display controller, generates a modulated data timing signal whose cycle changes within one frame period corresponding to the video data signal for one screen, and based on the data timing of the modulated data timing signal, supplies a gradation voltage signal corresponding to each of the video data to the predetermined number of data lines for each data period depending on the data timing of the modulation data timing signal.SELECTED DRAWING: Figure 1 【課題】装置規模の増大を抑えつつ、画質の劣化を抑制することが可能な表示装置を提供する。【解決手段】複数本のデータ線のうちの所定数のデータ線毎に設けられた複数のデータドライバを有する。複数のデータドライバの各々は、表示コントローラからシリアル化された映像データ信号の供給を受け、１画面分の前記映像データ信号に対応する１フレーム期間内において周期が変化する変調データタイミング信号を生成し、変調データタイミング信号のデータタイミングに基づいて、映像データの各々に対応した階調電圧信号を、前記変調データタイミング信号のデータタイミングに応じたデータ期間毎に前記所定数のデータ線にそれぞれ供給する。【選択図】図１
