A display panel module such as a liquid crystal display (LCD) panel module in an electronic apparatus is designed to receive a driving signal of a predetermined frequency. An electrically conductive frame or bezel of the display panel module tends to suffer from the transmission of electromagnetic waves which are related to the wavelength of the driving signal. An electrically conductive member is located behind the display panel and electrically connected to the electrically conductive frame. The electrically conductive member serves to diverge the electromagnetic waves out of the electrically conductive frame. This divergence of the electromagnetic waves serves to suppress the electromagnetic radiation out of the electrically conductive frame.
