Title: Liquid crystal display device using an alternative common voltage
Inventor: KIM HEON SU
IPC: G09G3/36
Filed: 2000-06-15
Abstract: An optical filter comprising a filter substrate (11) and a transparent conductive film (12) for cutting off electromagnetic waves and infrared rays (for example, a transparent conductive film sputter film), provided on the filter substrate (11) by alternately forming silver thin films and zinc oxide thin films into a multilayer structure. The transmissivity of image light outputted from a PDP (1) is a predetermined value (e.g. 60 %) or more and the surface resistance of the transparent conductive film (12) is 3 Omega/cm2 or less. In this way, the cutoff quantity (damping) of electromagnetic waves of a frequency of 30 to 130 MHz leaking from the PDP (1) is a predetermined value (e.g. 10 dB) or more, and the transmissivity of infrared rays of a wavelength of 800 to 1, 000 nm radiated from the PDP is predetermined value (e.g. 10 %) or less. Accordingly, the leakage level of electromagnetic waves leaking from the PDP (1) is below a restricted value, and interference with the operation of remote controllers, optical communication equipment, etc., disposed nearby is prevented by cutting off infrared rays radiated from the PDP (1). When warp of the filter substrate (11) (when it is a synthetic resin substrate, for example) due to heat generated by the discharge of the PDP (1) is a problem, the filter substrate (11) is made of glass (e.g. reinforced glass substrate) to prevent degradation of display quality due to the warp of the optical filter. When corrosion of the transparent conductive film (12) (particularly, a silver thin film) due to the water vapor in the open air is a problem, this corrosion can be prevented by covering the exposed surface of the transparent conductor film (12) with a moisture-proofing film. An AR film (13) is used to prevent reflection of external light so as to prevent the drop of contrast, and an AN film (14) is used to prevent the occurrence of Newton rings (bright and dark concentric circles).
