<p><P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device equipped with a noise cutoff means. <P>SOLUTION: This noise cutoff means is formed by a transparent film coated with a transparent conductive film, and is formed by dispersing a transparent conductive substance on an optical sheet. ITO and IZO are used for the transparent conductive substance. The noise cutoff means can be positioned between diffusion plates and the optical sheets, and can be positioned in the lower part of a LCD panel. Therefore, noise generated from a power source supplied to a back light assembly is cut off from the LCD panel. The noise cutoff means and the optical sheet are brought into contact with the chassis of the LCD display device by various grounding means. Therefore, the noise cutoff means and the optical sheet are stabilized by grounding them. Thereby, display quality of the LCD device can be enhanced. <P>COPYRIGHT: (C)2004,JPO</p> |
