Abstract
An optical filter including: a base film; and a function incorporation layer on the base film and for shielding electromagnetic interference and absorbing external light, the function incorporation layer having a cross mesh pattern, wherein the cross mesh pattern includes a plurality of pattern lines, and wherein at least a part of the cross mesh pattern protrudes from a surface of the function incorporation layer facing toward the reflection prevention layer.

An optical filter comprising:
- a base film;
- and
- a function incorporation layer on the base film and for shielding electromagnetic interference and absorbing external light, the function incorporation layer having a cross mesh pattern,
- wherein the cross mesh pattern comprises a plurality of pattern lines, each pattern line having a height, not all heights of the pattern lines being the same, and
- wherein at least a part of the cross mesh pattern protrudes from a surface of the function incorporation layer.

A display device comprising:
- a display panel;
- a base film on the display panel;
- and
- a function incorporation layer on the base film and for shielding electromagnetic interference and absorbing external light, the function incorporation layer having a cross mesh pattern,
- wherein the cross mesh pattern comprises a plurality of pattern lines, each pattern line having a height, not all heights of the pattern lines being the same, and
- wherein at least a part of the cross mesh pattern protrudes from a surface of the function incorporation layer.

A display device comprising:
- a display panel;
- a base film on the display panel;
- a function incorporation layer on the base film and for shielding electromagnetic interference and absorbing external light, the function incorporation layer having a cross mesh pattern;
- a reflection prevention layer on the function incorporation layer and having a size for exposing at least one edge portion of the cross mesh pattern to ground the cross mesh pattern,
- wherein at least a part of the cross mesh pattern protrudes from a surface of the function incorporation layer facing toward the reflection prevention layer,
- wherein the cross mesh pattern comprises:
- a plurality of first pattern lines parallel to each other and separated by a first interval, each of the plurality of first pattern lines extending in a first direction and having a first width and a first height;
- and
- a plurality of second pattern lines parallel to each other and separated by a second interval, each of the plurality of second pattern lines extending in a second direction crossing the first direction and having a second width and a second height,
- wherein when the first width is set to be substantially identical to the second width, the second height is smaller than the first height, and the second interval is larger than the first interval, and
- wherein each of the first and second pattern lines comprises:
- a first conductive layer;
- and
- a second conductive layer at least partially within the first conductive layer.
