Electromagnetic shielding member for display device 'This member is used to be placed on the front side of a display panel such as a plasma display panel for the purpose of shielding electromagnetic waves and preventing reflection of external light. Description of the Related Art Among electronic devices such as electronic tubes for display, which are often used on the side of people, and traditionally consider the harmful effects of electromagnetic waves on the human body, they are required to be emitted from these devices. Electromagnetic waves must fall within the specified range. Plasma display panels (hereinafter also referred to as "PDPS") have small size and light weight. Therefore, they have been widely used as display devices in recent years. However, P D P s uses a plasma area discharge for emitting light, and tends to leak out unnecessary electromagnetic waves with a frequency of 30 to 130 MHz. For this reason, in P D P s, it is particularly necessary to suppress electromagnetic waves as much as possible so as not to interfere with other devices (for example, information processors, etc.). Further, in a display panel such as P D P s, it is generally necessary to prevent reflection of external light, so as to avoid a drop in image contrast. In the imaging device using P D P s, the screen is flat. Therefore, when external light enters the screen and is widely reflected, the reflected light also conforms to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) on this paper scale ----- · --I 4 — II i II — II 1 ^ · I I --- 丨 丨 -line.

Description of the invention (2) Can enter into the eyes of the viewer 'makes the image on the screen inconspicuous. For this reason, it is particularly necessary to prevent reflection of external light in such a device. In addition, in P D P s, it is also necessary to suppress near-infrared rays emitted when p d P s emits light. The reason for this suppression is as follows: The wavelength of near-infrared is close to that used by remote control equipment, optical communication devices, and the like. Therefore, when these devices and devices are operated near PDPs, their normal operation will be disturbed. . In addition, in P D P s, it is also necessary to transmit visible light with a predetermined transmittance to achieve a good image display. To meet these requirements, the following methods have traditionally been adopted in PDPs: a plate-like member is prepared by inserting a thin film having a function of shielding electromagnetic waves or cutting off infrared rays between two glass plates, and the plate-like member is placed on A PDP s has previously been used as a mechanism to shield electromagnetic waves or cut off infrared rays. A plate-shaped member placed on the front side of a display panel such as P D P s is generally referred to as a front panel of a display panel or an electromagnetic shielding member. SUMMARY OF THE INVENTION However, the aforementioned conventional display panel has a problem that the front panel has a very heavy weight. In addition, it has another problem, that is, the front panel cannot satisfy all the requirements regarding shielding electromagnetic waves, cutting off infrared rays, preventing reflection of external light, transmission and reception of visible light, and the like.
