Abstract

Each of a plurality of first electrodes extending along a first direction and arranged along a first cross direction crossing the first direction on a first surface of a transparent dielectric layer includes a plurality of first electrode lines each having a bending line shape extending in the first direction. A region between two of the first electrode lines adjacent to each other in the first cross direction is an intermediate region, the intermediate region includes an increase region in which the length of the intermediate region in the first cross direction increases along the first direction, and a decrease region in which the length of the intermediate region in the first cross direction decreases along the first direction, and the increase regions and the decrease regions are alternately disposed along the first direction.

Description

technical field [0001] The present invention relates to a conductive film including a plurality of electrode lines, a touch panel including the conductive film, and a display device including the touch panel. Background technique [0002] A display device that uses a touch panel as an input device includes a display panel that displays an image, and the touch panel that overlaps the display panel. As a method for detecting a contact position of a finger or the like on the touch panel, a capacitive method that detects contact of a finger or the like with the operation surface of the touch panel as a change in capacitance is widely used. In the capacitive touch panel, the conductive film included in the touch panel includes a plurality of first electrodes extending in a first direction and a plurality of second electrodes extending in a second direction perpendicular to the first direction. , and a transparent dielectric layer sandwiched between the first electrode and the se...
