Provided is a display device that reduces power consumption, and has a display unit and an image signal drive circuit integrally formed with one another. A source driver (300) is configured from a shift register (310) and a sampling circuit (320). The sampling circuit (320) is configured from sampling blocks (40(1)-40(k)). Each sampling block is configured from three thin-film transistors. The shift register outputs selection signals (SEL(1)-SEL(k)) on the basis of a source clock signal (SCK2). The selection signals (SEL(1)-SEL(k)) are assigned to the sampling blocks (40(1)-40(k)). A scanning period (T1) is followed by an idle period (T2). During the idle period (T2), the shift register (310) operates on the basis of the source clock signal (SCK) of the idle period frequency (fck2). The idle period frequency (fck2) is lower than the scanning period frequency (fck1). |
