Abstract

The present invention discloses a conductive film and a display apparatus provided with the conductive film. A conductive film is disposed on a display panel of a display apparatus, and has a base body, and a conductive section formed on one of the main surfaces of the base body. The conductive section has a mesh pattern composed of fine metal lines, and the fine metal lines have a tilt of 30-44° with respect to the alignment direction of pixels of the display apparatus.

First claim

The invention claimed is:

1. A conductive member for a display panel comprising
a first conductive part having a first pattern,
a second conductive part having a second pattern, and electrically isolated from the first conductive part,
wherein a combined pattern of an overlay of the first pattern of the first conductive part and the second pattern of the second conductive part forms a mesh pattern,
the mesh pattern has a rhombic shape,
a vertex angle of the rhombic shape has at an angle of 60° to 88° or 92° to 120°,
the rhombic shape has an angle of 30° to 44° or 46° to 60° with respect to a first direction,
the first direction is parallel to an arrangement direction of pixels of the display panel.

2. A touch sensor comprising the conductive member according to claim 1 .

3. A touch panel comprising the conductive member according to claim 1 .

4. A conductive member for a touch panel display comprising
a first conductive part having a first pattern,
a second conductive part having a second pattern and electrically isolated from the first conductive part,
wherein an overlay of the first pattern of the first conductive part with the second pattern of the second conductive part forms a mesh pattern,
wherein an opening of the mesh pattern has a rhombic shape;
a vertex angle of the rhombic shape has at an angle of 60° to 88° or 92° to 120°,
the rhombic shape has an angle of 30° to 44° or 46° to 60° with respect to a first direction,
the first direction is parallel to an arrangement of pixels of the display panel.

5. A touch sensor comprising the conductive member according to claim 4 .

6. A touch panel comprising the conductive member according to claim 4 .
