A button device of a display module is provided to simplify a button structure of a display unit by integrating a button unit with a frame which is formed on a circuit board. A button device of a display module includes a printed circuit board(110), a frame(120), and a button unit(130). The printed circuit board has a plurality of tact switches for generating different signals. The frame is formed on the printed circuit board, and penetrates a button hole to be consistent with the tact switch. The button unit is formed on the button hole of the frame to be exposed to the external. The button unit elastically operates the corresponding tact switch in a push operation. A lighting member for displaying an operation state of the tact switch is formed on the printed circuit board. A display hole is penetrated on the frame to expose the lighting member to the external.
