A multi-function telephone dialer display device which is equipped with a display screen for displaying the use status and the caller identification information, and a dialer for responding to data input and for generating a data signal to the display screen to display the corresponding use status. When dialing with numerical keys, with standard non-numerical keys or when setting up a function, the data signal is coded into a numerical code representing the original digit, coded into a standard non-numerical code representing the original non-numerical keys or coded into a function key code representing the function, respectively. A display driver is electrically connected to the display screen, to the telephone dialer and to a caller data signal line for receiving and processing the data signals, the timing signals and the identification signal representing the caller information, and then transferring the result of the processing to the display screen for displaying a corresponding status and caller identification information.
