ABSTRACT:
An improved flat display apparatus such as a liquid crystal display apparatus is disclosed. The apparatus is constructed so that when video signals from a VTR is reproduced to be displayed, the switching noise portion included in the video signals is changed to black level before being displayed, the section within the picture image area in which the switching noise originally appeared is masked by black level, making it possible to conceal the disorder in the picture image. In the case where television video signals are to be displayed, the picture can be enjoyed on a wide picture image area because the mask of black level is not generated.
