Abstract
A display filter and a display apparatus including the display filter increase a contrast ratio, increase brightness, and have a great electromagnetic (EM) radiation-shielding effect. The display filter includes a filter base and an external light-shielding layer formed on a surface of the filter base. The external light-shielding layer includes a base substrate including a transparent resin and light-shielding patterns spaced apart on a surface of the base substrate at predetermined intervals, and including a conductive material.
Claims9
A display filter comprising:
- a filter base;
- and
- an external light-shielding layer formed on a surface of the filter base, wherein the external light-shielding layer comprises a base substrate including a transparent resin and light-shielding patterns spaced apart on a surface of the base substrate at predetermined intervals, and including a conductive material;
- and
- an electrode pattern disposed at both ends of the light-shielding patterns to be substantially perpendicular to the light-shielding pattern, thereby connecting the light-shielding patterns, wherein
- the filter base comprises an electromagnetic (EM) radiation-shielding layer including a multi-layered transparent conductive film formed by stacking a metal thin film and a transparent thin film having a high refractive index.
