Abstract

A display filter for a display device can reduce moire patterns and remove air pollutants. The display filter includes a transparent substrate located in front of a display module of the display device and an anti-glare layer provided at a front of the display filter which is exposed to the outside. The anti-glare layer contains photo-catalyst particles as filler.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2008-0128329 filed with the Korean Intellectual Property Office on December 17, 2008, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to display filters capable of reducing moiré patterns and removing airborne contaminants. Background technique [0004] With the emergence of an advanced information society, components and devices related to optoelectronics have been remarkably improved and spread rapidly. Among them, image display devices have been widely used in televisions, personal computer (PC) monitors, and the like. In addition, various attempts are being made to increase the size while reducing the thickness of these display devices. [0005] In general, plasma display panel (PDP) devices have advantages due to their large size and thin profile, compared to cathode r...
