摘要:
A light emitting element is provided to allow for resetting a shift register while keeping a frame narrow without increasing complexity of a shift register circuit. A display apparatus has a data line, a scanning line, a pixel circuit, a shift register circuit, a first power supply supplying a voltage to the shift register circuit and a second power supply supplying a voltage to the pixel circuit. One end of the scanning line is connected to an output of the shift register circuit, and writing of a data signal from the data line to the pixel circuit can be controlled by a scanning signal from the scanning line. When the first power supply is on, any one of a high-level signal and a low-level signal is input into the shift register circuit for the number of stages of the shift register, and thereafter, the second power supply is turned on.
