Abstract
Disclosed are a display filter, a display device comprising the filter and a production method for the filter. The disclosed display filter comprises a base section and a pattern section which is formed on the base section. The pattern section is formed from an adhesive material comprising metallic powder. The metallic powder is included at 10-30 parts by weight relative to the pattern section. Thus, bright room contrast can be improved by blocking light coming from outside, and electromagnetic waves generated from within a panel can be reduced.
Claims23
A display filter comprising:
- a base section;
- and
