Problems solved by technology

The wavelength of such NIR radiation is very close to the wavelength of the remote control, which may cause electrical failure
In addition, the glass provided on the front of the PDP reflects external light, causing glare, decreased contrast, etc.

Abstract

An optical filter wherein a hard coating layer and an electromagnetic shielding layer are integrally formed and a method of manufacturing the optical filter. The optical filter includes a base film, and a hard coating layer formed on one surface of the base film, the hard coating layer having conductive substances positioned in a region adjacent to the base film. The method includes preparing a light-transmissive base film; coating a liquid hard coating raw material on one surface of the base film, the hard coating raw material having conductive substances mixed therewith; and curing the hard coating raw material in the state that the conductive substances are concentrated on a region adjacent to the base film, and the hard coating raw material is formed between and on the conductive substances.

Description

technical field [0001] The present invention relates to an optical filter including a hard coating layer and an electromagnetic shielding layer and a manufacturing method thereof. Background technique [0002] A plasma display device including a plasma display panel (PDP) is a flat panel display device that displays images using a gas discharge phenomenon. Plasma display devices are superior to conventional cathode ray tubes (CRTs) in terms of brightness, contrast, afterimage, and viewing angle characteristics. [0003] Since high voltage and high frequency are used in the driving process of the aforementioned plasma display device, a large amount of electromagnetic waves are radiated to the front of the PDP. In addition, the plasma display device emits near infrared (NIR) radiation induced by an inert gas (eg, Ne or Xe). The wavelength of such NIR radiation is very close to that of the remote controller, which may cause electrical malfunctions. In addition, the glass dis...
