PROBLEM TO BE SOLVED: To provide a touch detection device capable of suppressing deterioration of accuracy of position detection while shortening time required for scanning the whole screen, a display device with a touch detection function, and an electronic apparatus.SOLUTION: In a touch detection period, plural drive electrodes COML to which drive signals are applied from a drive electrode driver 14 are divided into drive signal application blocks B1-Bm. By arranging parts of the drive electrodes COML at the end parts of adjacent drive signal application blocks so as to change its alignment sequence, block overlapping parts L1, L2, ..., Lm-1 with which the adjacent drive signal application blocks are overlapped are formed. The drive electrode driver 14 sequentially applies a touch detection drive signal to each drive signal application block. |
