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.
