An active matrix display apparatus is disclosed which can achieve significant improvement in uniformity. The display apparatus uses a horizontal driving circuit to which a precharge function is provided additionally. The horizontal driving circuit applies double sampling pulses including first and second pulses to each sampling switch. The first pulse is used to precharge a signal line with an image signal, and the second pulse is used to sample the image signal to the signal line. Where the second pulse of double sampling pulses applied to a preceding sampling switch and the first pulse of double sampling pulses applied to a succeeding sampling switch are in a temporally overlapping relationship with each other, image lines of different systems from each other are connected to the preceding sampling switch and the succeeding sampling switch thereby to prevent otherwise possible interference of the image signal between the two sampling switches.
