    • In one embodiment, a liquid crystal display device includes first and second areas respectively having a gate line group in an active area, and a dummy gate line group arranged on an outside of the active area. A driving circuit selects the gate lines of the gate line group and the dummy gate lines of the dummy gate line group one by one in the first and second areas. The driving circuit is independently controlled for the first and second areas. The gate lines are scanned from a center portion of the active area to the dummy gate line side in the first and second areas, respectively. An image signal and a non-image signal are written within one-frame period in the first and second areas.
    • 在一个实施例中,液晶显示装置包括分别在有源区域中具有栅极线组的第一和第二区域,以及布置在有源区域外部的虚拟栅极线组。 驱动电路在第一和第二区域中逐个选择栅极线组的栅极线和虚拟栅极线组的虚拟栅极线。 对第一和​​第二区域独立地控制驱动电路。 栅极线分别从有源区域的中心部分扫描到第一和第二区域中的虚拟栅极线侧。 图像信号和非图像信号在第一和第二区域的一帧周期内被写入。

    • A liquid crystal display device includes display pixels which are arrayed in a matrix, a driver circuit which drives the display pixels in units of a predetermined number of rows, and a controller which controls the driver circuit so as to alternately execute non-video signal write in which a non-video signal is written by driving the display pixels on a row-by-row basis, and video signal write in which a video signal is written by driving the display pixels on a row-by-row basis. Each of the display pixels includes a first capacitance which is formed by a voltage applied between electrode substrates, and a second capacitance which is coupled to the first capacitance. The controller includes a control circuit which controls the driver circuit so as to charge a predetermined capacitance on the second capacitance in a superimposing manner during a time period in which the non-video signal write is executed.
