    • A display device includes: a pixel array including pixel circuits arranged in a matrix state, in which each pixel circuit has a light emitting element, a drive transistor, and a storage capacitor storing a threshold voltage of the drive transistor and an inputted signal value; a threshold correction operation means for performing a threshold correction operation plural times, which allows the storage capacitor to store the threshold voltage of the drive transistor before giving the signal value to the storage capacitor; and a cut-off control means for allowing the drive transistor to be cut off in at least one after-correction period and for allowing the drive transistor not to be cut off in at least one after-correction period in plural after-correction periods which are periods after the plural threshold correction operation periods.
    • 显示装置包括:像素阵列,包括以矩阵状态布置的像素电路,其中每个像素电路具有发光元件,驱动晶体管和存储驱动晶体管的阈值电压的存储电容器和输入的信号值; 阈值校正操作装置,用于多次执行阈值校正操作,其允许存储电容器在将信号值提供给存储电容器之前存储驱动晶体管的阈值电压; 以及截止控制装置,用于允许驱动晶体管在至少一个后校正周期中被切断,并且用于允许驱动晶体管在多个后校正周期中的至少一个后校正周期中不被切断, 是在多个阈值校正操作期间之后的周期。
