Abstract

A source electrode driving circuit for a matrix type liquid crystal display apparatus, provided respectively in the plurality of partial source electrode driving circuits, are adapted to output the sampling signal into the shift register. Sample signals are output after repeating operations of counting clock signals, the number of clock signals being equal to the number of the stages of the shift register, this number being externally set, with an inputted timing signal as the reference. Thus, the connection signal between the partial source electrode driving circuits which causes the image disturbances, is not required. This therefore provides superior display images.
