Touch panel

摘要

Providing a touch panel that suppresses reflection of light and prevents a reduction in the visibility of an image even when strong outside light is incident thereon in an outdoor environment. The touch panel has a plurality of first electrodes juxtaposed in parallel to each other in a first direction and a plurality of second electrodes juxtaposed in parallel to each other in a second direction. The first electrodes are continuously formed, the second electrodes are discontinuously formed, and a connecting electrode that electrically connects each parts of each of the second electrodes at a discontinuous portion is arranged under each of the first electrodes through an interlayer insulating film. A contour line provided to the interlayer insulating film arranged on the connecting electrode is formed to be curved under each of the first electrodes or the second electrodes.

1. A capacitive touch panel comprising:
a plurality of first electrodes, extending in a first direction, arranged juxtaposed in parallel to each other in a second direction intersecting with the first direction on a transparent substrate; and a plurality of second electrodes, extending in the second direction, arranged juxtaposed in parallel to each other in the first direction, wherein at intersect portions at which the first electrodes intersect with the second electrodes, the first electrodes are continuously formed and the second electrodes are discontinuously formed, wherein a connecting electrode that electrically connects each part of each of the second electrodes at a discontinuous portion is formed under each of the first electrodes through an interlayer insulating film, wherein the interlayer insulating film is formed island like on the connecting electrode in a plan view, a contour line of the interlayer insulating film has a curved portion under each of the first electrodes or the second electrodes in a plan view, wherein the contour line has a first linear portion which extends parallel along the first direction and reflects an outside light, wherein the interlayer insulating film has a top surface, a bottom surface and a side surface connecting the top surface and bottom surface, wherein the side surface surrounds one of the intersect portion, wherein the contour line is defined by a boundary between the bottom surface and the side surface of the interlayer insulating film, wherein the second electrode overlaps with the side surface and the top surface of the interlayer insulating film, wherein a length of the first linear portion is shorter than a width of the interlayer insulating film parallel to the first direction and a width of the connecting electrode parallel to the first direction in a plan view, wherein the curved portion of the contour line gradually and continuously changes its direction in a plan view and an angle made by the curved portion and the first linear portion of the contour line is larger than 90 degrees, wherein a dimension of the interlayer insulating film in the second direction is larger than a dimension of the interlayer insulating film in the first direction, and wherein the second direction is set to a horizontal direction, which coincides to an arrangement of eyes of a human being.
