An electronic module includes an electronic circuit board having circuit elements, signal lines connected to the circuit elements, and board terminals disposed on a terminal region, and an input board and driver circuit boards mounted on the terminal region of the electronic circuit board. Each of the driver circuit boards has input terminals and output terminals. The output terminals are electrically connected to the signal lines of the electronic circuit board. The input board has main wiring lines for transmitting signals input externally, and branch wiring lines branched from the main wiring lines. The branch wiring lines are electrically connected to the input terminals of the driver circuit boards via the board terminals of the electronic circuit board.
