Abstract
Abstract A display module comprises a display device for displaying visual information, an electrode disposed on the display device, a circuit board for carrying wiring lines connected to circuit elements for driving the display deivce, and a conductive elastomer body for connecting the wiring lines and the electrode, the conductive elastomer body being placed between the electrode and a curled edge a flange of the circuit board. In a specific form, the display device is a liquid crystal display cell.
