Abstract
Abstract A display device can be capable of suppressing electromagnetic interference and be easily disassembled into pieces of different materials such as plastics and metallic materials. A duct is formed in a part of a plastic frame and a shielding case having resilience is pressed from above into position on the duct. Furthermore, modules are attached on the frame, which is then mounted to the body of the device. Thus, the lower part of the shielding case contacts the metallic bottom chassis to thereby shield cables of a front module. Thus, the plastic material of the front module and the metallic material of the cable shielding case and others, being separable into different pieces, can easily be recovered for recycling purposes.
