Abstract

This application discloses an active-matrix display device capable of providing satisfactory display free from display irregularities on a non-rectangular display portion, such as a notched display portion, while avoiding an increased circuit scale and other adverse factors. In such an active-matrix liquid crystal display device including a notched display portion, pulses of gate clock signals GCK and GCKB corresponding to pulses of scanning signals are subjected to waveform rounding in accordance with time constants of scanning signal lines to which the scanning signals are to be applied. As a result, the waveforms of all scanning signals to be applied to the scanning signal lines are rounded to almost the same degree. Thus, each pixel forming portion is approximately equal in pixel voltage reduction amount ΔVp upon turning off of a pixel switching element.
