Abstract
The present invention relates to an image distortion prevention filter in which a pattern having an irregular shape is formed on a transparent substrate, and a manufacturing method thereof. According to the present invention, formation of a metal pattern having an irregular shape on a transparent substrate may have an effect of preventing glare caused by a periodic pattern and blocking light diffraction and interference, thereby preventing image distortion.
Claims17
A filter for preventing a distortion of an image, comprising:
- a transparent substrate;
- and
- a metal layer comprising a metal pattern having an irregular shape and formed by depositing conductive metal on one surface of the substrate,
- wherein diffraction and interference phenomena of light are blocked by an irregular structure of the pattern.
A method of manufacturing a filter for preventing a distortion of an image, the method comprising:
- a pattern mask generation step of generating a pattern mask comprising a pattern having an irregular shape;
- a substrate preparation step of preparing a transparent substrate;
- and
- a metal layer forming step of forming a metal layer comprising the pattern having the irregular shape on the transparent substrate.
