Display device

一种显示设备，把沿x方向延伸的虚线作为边界，把作为象素区域的集合的显示区域划分成两个分离的显示区域。分别形成把扫描信号供给到在一个显示区域中的相应栅极信号线的扫描信号驱动电路、和把扫描信号供给到在另一个显示区域中的相应栅极信号线的扫描信号驱动电路。把在一个显示区域处的漏极信号线与在另一个显示区域处的漏极信号线分离。分别形成把视频信号供给到在一个显示区域中的相应漏极信号线的视频信号驱动电路、和把视频信号供给到在另一个显示区域中的相应漏极信号线的视频信号驱动电路。由此能得到具有很小功率消耗的显示设备。 A display device having gate signal lines, a scanning signal driving circuit which supplies scanning signals to respective gate signal lines, drain signal lines, and a video signal driving circuit which supplies video signals to respective drain signal lines formed on one surface of an insulating substrate. The display device includes a first thin film transistor which is driven by the scanning signals, a pixel electrode to which the video signals are supplied through the first thin film transistor in each pixel region. The video signal driving circuit includes a dynamic memory which is comprised of a plurality of other thin film transistors formed in parallel with the first thin film transistor, and at least one thin film transistor among the plurality of other thin film transistors is covered with a conductive film having a potential which is fixed through an insulation film.
