にある。In the past, since a metal material such as magnesium was used for the housing in order to secure the strength of the housing, there was no problem that static electricity was released to the ground and static electricity was generated in the liquid crystal display device. In consideration of the environment and mass production, the number of cases in which a housing is molded with almost no resin, which does not include a metal material, is increasing. Further, in recent years, since contents such as still images and moving images are displayed on a liquid crystal display device, the display range is becoming larger, and the influence of static electricity tends to be more likely.
