    Abstract: The present invention provides technology for decreasing a reduction in yield due to malfunctions of a touch panel. A display device with a touch panel according to the present invention includes a display panel that includes pixels arranged in a matrix and a plurality of first electrodes and second electrodes for detecting a touched position in a display region provided with the plurality of pixels by capacitive sensing. The first electrodes extend in a first direction in the display region, and the second electrodes extend in a second direction that crosses the first direction in the display region. The display panel includes repairing conductive sections that are formed of conductive members. The repairing conductive sections are provided in such a manner that at least one repairing conductive section is provided for each of the plurality of first electrodes and is arranged along at least part of the first electrode.

    Abstract: A touch panel pattern TPP includes detection electrodes 38, driving electrodes 39, floating electrodes 45, and reference width floating electrode 48, a smallest width floating electrode 49, and an intermediate width floating electrode 50 that are included in the floating electrodes 45. The smallest width floating electrode 49 is disposed at an end-side one of the floating electrodes 45 with respect to a second direction and has a smallest width. The intermediate width floating electrode 50 is disposed closer to the end-side one than the reference width floating electrode 48 is and closer to a middle than the smallest width floating electrode 49 is and has a width FW2 smaller than that of the reference width floating electrode 48 and larger than that of the smallest width floating electrode 49.
