WIPO Patent Application WO/2018/147109
Kind Code:
A1
Abstract:
[Problem] To provide a display device that is easy to make thin and in which interference between a sensor electrode and an NFC antenna is unlikely to occur. [Solution] A display device 100 comprises: a touch panel 10; a display module 20; a metal frame 30; and an NFC antenna 7. The touch panel 10 includes: a plate-shaped transparent substrate 11, the front side of which serves as an operation surface; a transparent resin layer 13 that is disposed on the rear side of the transparent substrate 11 so as to be superimposed with the transparent substrate 11; and touch-operation-detection sensor electrodes 15 that are provided on the front side and/or rear side of the transparent resin layer 13 so as to be superimposed with a display region 10a. The metal frame 30 is disposed on the rear side of the transparent resin layer 13 so as to be superimposed with a non-display region 10b. The NFC antenna 7 is constituted by a loop-shaped antenna pattern 7a provided on the front side of the transparent resin layer 13 so as to be superimposed with the non-display region 10b.
