Abstract:
The subject invention provides a drive circuit for a display apparatus, comprising: a shift register; and a pulse generation circuit for generating a drive pulse signal using an output pulse signal generated in the shift register, wherein: the pulse generation circuit forms a pulse-starting edge and a pulse-termination edge of the drive pulse signal using a rise or a fall of pulse resulting from activation of the output pulse signal. On this account, pulse generation can be performed with high accuracy in a pulse generation circuit used for a drive circuit for a display apparatus or the like.
