To provide a display device with low power consumption that supports a high refresh rate and can display an image with a high display quality, and a method for controlling the display device.SOLUTION: A liquid crystal display device includes a liquid crystal display panel including a plurality of gate bus lines, and a control device 50. The control device 50 includes a first gate driver 71 connected to one end of each of the plurality of gate bus lines GL and a second gate driver 72 connected to another end of each of the plurality of gate bus lines. The control device receives an image signal, generates a gate signal based on the image signal, and inputs the gate signal to only the first gate driver or to the first gate driver and the second gate driver, in accordance with a refresh rate of the image signal.SELECTED DRAWING: Figure 4 【課題】高リフレッシュレートに対応し、高い表示品位で画像を表示することのできる低消費電力の表示装置および表示装置の制御方法を提供する。【解決手段】液晶表示装置は、複数のゲートバスラインを含む液晶表示パネルと、制御装置５０とを備える。制御装置５０は、複数のゲートバスラインＧＬの一端に接続された第１ゲートドライバ７１と、複数のゲートバスラインの他端に接続された第２ゲートドライバ７２とを含み、映像信号を受け取り、映像信号に基づいてゲート信号を生成し、映像信号のリフレッシュレートに応じて、ゲート信号を第１ゲートドライバのみ、または、第１ゲートドライバおよび第２ゲートドライバへ入力する。【選択図】図４
