Abstract
A display apparatus includes a pixel circuit, a scanning line for supplying a scanning signal to the pixel circuit, a data line for supplying a data signal to the pixel circuit, and a shift register circuit having a number of stages, with every stage outputting the scanning signal to the scanning line. In addition, a first power supply supplies a voltage to the shift register circuit, and a second power supply supplies a voltage to the pixel circuit. After the first power supply is turned on, a constant level signal of either 'H' or 'L' is input into a terminal of the shift register circuit by clocks of the number of stages of the shift register such that every stage of the shift register outputs a same level signal before the second power supply is turned on.
