    • A high-speed flat panel display having a long lifetime. Thin film transistors in a pixel portion having a plurality of pixels are contacted differently from thin film transistors in driving circuit portions for driving the pixels, thereby enhancing luminance uniformity and reducing power consumption. The thin film transistors each have a channel region and a body contact region for applying a predetermined voltage to the channel region. At least one thin film transistor in the pixel portion is a source-body contact thin film transistor having the body contact region connected to one of source and drain electrodes so that the predetermined voltage can be provided to the channel region. Each thin film transistor in the driving circuit portion is a gate-body contact thin film transistor having the body contact region connected to the gate electrode so that a predetermined voltage can be provided to the channel region.
    • 一种寿命长的高速平板显示器。 具有多个像素的像素部分中的薄膜晶体管与用于驱动像素的驱动电路部分中的薄膜晶体管不同地接触,从而增强亮度均匀性并降低功耗。 薄膜晶体管各自具有用于向沟道区施加预定电压的沟道区和体接触区。 像素部分中的至少一个薄膜晶体管是源体接触薄膜晶体管,其具有连接到源极和漏极之一的主体接触区域,从而可以将预定电压提供给沟道区域。 驱动电路部分中的每个薄膜晶体管是具有连接到栅电极的体接触区域的门体接触薄膜晶体管,从而可以向沟道区域提供预定电压。
