AbstractAn active matrix liquid crystal display device operable on an interlaced scanning scheme and having a plurality of liquid crystal cells and switching active elements for driving the liquid crystal cells. The liquid crystal cells and the switching active elements are arranged in a matrix fashion having rows and columns intersecting with each other. The display device comprises a plurality of sets of rows, each set being comprised of neighboring members of the rows of the matrix; a scanning unit for scanning each set with an interlaced scanning signal during any field, odd-numbered source lines each connected with one of the row forming the respective set, even-numbered source lines each connected with the other of the row forming the respective set; and a signal applying unit for applying an odd-numbered field signal to the odd-numbered source line during any field time and for applying an even-numbered field signal to the even-numbered source line during any field time.
