Abstract: A display surface of the present invention includes a display operation surface (2) including an input operation surface (2a) that constitutes at least a part of the display operation surface (2), the input operation surface (2a) being configured to be directly touched by a user so that an input operation is performed, the input operation surface (2a) having a first region (3) and a second region (4) which are provided in a single substrate, the first region (3) being planar and substantially flat, and the second region (4) being protruded and/or recessed with respect to a reference plane which is an input surface the first region (3). It is therefore possible to realize (i) a touch panel which has further improved operator's operability and is provided to an electronic device having multi-functions, (ii) a display device including the touch panel, and (iii) an electronic device including the touch panel.

Abstract: A touch panel (20a) including: a touch detection electrode (11) provided on a first substrate (10); a lead line (13a, 13b) routed from the touch detection electrode (11) along a periphery of the first substrate (10) to an area along one side edge of the first substrate (10), the lead line including a connection terminal T formed in the area; and an external line (16) provided on a second substrate (15a) secured to the area along the one side edge of the first substrate (10) and connected to the connection terminal (T), wherein the connection terminal (T) of the lead line (13a, 13b) is formed in a linear pattern along the one side edge of the first substrate (10), and the external line (16) includes a connection portion (16a) provided so as to overlap the connection terminal (T), and a line portion (16b) bending from the connection portion (16a) to extend in a direction away from the touch detection electrode (11).

Abstract: A display device (40a) includes a touch panel (20a) installed in a display screen (S), the touch panel including: a touch detection electrode (11a) arranged at a first substrate (10) so as to be capable of detecting a touch; and a lead wiring (13a) connected to the touch detection electrode (11a) for detecting a touched position at the touch detection electrode (11a), wherein at least part of the lead wiring (13a) is arranged at a second substrate (15a) arranged adjacent to the first substrate (10).
