TOUCH SENSOR BOARD, IMAGE DISPLAY DEVICE, AND TOUCH SENSOR BOARD MANUFACTURING METHOD

摘要

To provide a touch sensor board and the like capable of improving the visibility of the screen and the manufacture yield simultaneously. The touch sensor board includes a plurality of mutually parallel first electrodes extended along a first direction and a plurality of mutually parallel second electrodes extended along a second direction. Regarding the first and second electrodes, one of those is connected to each electrode element via a same-layer connection pattern while the other is connected to each electrode element via a different-layer connection pattern. The same-layer connection pattern and the different-layer connection pattern overlap on one another via an interlayer film formed by an insulator. Further, the interlayer film is continued from the overlapping part between the same-layer connection pattern and the different-layer connection pattern via a gap part between each of the electrode elements, and the interlayer film is formed to be continued in the gap part.

1. A static capacitive type touch sensor board formed on a transparent board, comprising:
a plurality of mutually parallel first electrodes extendedly provided by connecting polygonal electrode elements on a same layer of the transparent board along a first direction via connection patterns; and a plurality of mutually parallel second electrodes extendedly provided by connecting polygonal electrode elements on the same layer as that of the first electrodes along a second direction via connection patterns, wherein: regarding the electrode elements of the first and second electrodes, each of the electrode elements that are electrically equivalent is connected via a same-layer connection pattern or a different-layer connection pattern, and the same-layer connection pattern and the different-layer connection pattern overlap with each other via an interlayer film that is formed by an insulator; and the interlayer film is continued from a part where the same-layer connection pattern and the different-layer connection pattern overlap with each other via a gap part between each of the electrode elements, the interlayer film is formed to be continued in the gap part, and the interlayer film is not formed practically in a region where the first and second electrodes are formed.
