Abstract
In a thin-type liquid crystal display device of this invention, a display section is formed on a printed circuit board and has a matrix array of display cells, address lines connected to the row arrays of the display cells and data lines connected to the column arrays of the disply cells. Row and column switching selectors are provided on the printed circuit board. The respective selectors include a parallel array of switches, such as TFTs. The row selector is connected to the address lines for sequentially selecting address lines through a scanning operation for image display. The column selector is connected to the data line for subjecting an incoming frame of image data to a time-division multiplexing and for sequentially supplying block-segmented image data components to the data lines.
