The liquid crystal unit 11 is connected to a liquid crystal display control circuit 12 through a connector 24 and a cord 25. An operating switch 13 is connected to the liquid crystal display control circuit 12 through a cord 26, and the liquid crystal display control circuit 12 is connected to a character, graphic and symbol output device of a computer, a word processor, etc., through a cord 27. In such a way, output information of the computer, the word processor, etc., can be displayed easily and exactly without necessitating a preparation of an OHP film, etc.
