    Abstract: The reliability of a display device with an input device is improved. A plurality of detection electrodes (input position detection electrodes) forming an electrostatic capacity between them and a common electrode of a display device to detect an input position are formed on a different substrate from substrates configuring the display device. Moreover, a polarizing plate and the substrate on which the plurality of detection electrodes are formed are adhesively fixed via, for example, an adhesive layer so that the plurality of detection electrodes are fixed so as to be separated apart from the display device. Thus, a distance between electrodes (the detection electrode and a driving electrode) for detecting an input position can be set separately from a thickness of the display device, and therefore, reduction in detection sensitivity (detection reliability) for the input position due to increase in the electrostatic capacity can be suppressed.

    Abstract: A first substrate includes a gate line extending in a first direction, a source line extending in a second direction intersecting the first direction, a switching element which is connected to the gate line and the source line, and a pixel electrode which is connected to the switching element. The first substrate includes a common electrode which is opposed to the pixel electrode, and a detection electrode element necessary for sensing a state of closeness of a conductor brought externally, that extends parallel to the common electrode and is formed of a metallic material. By this structure, power consumption of a drive electrode of an input sensor can be reduced, and improvement of a drive frequency can be obtained.

    Abstract: A noise immunity of a detected capacitance is prevented or inhibited from lowering on a driving electrode different in width from the other driving electrodes, provided in an input device. A touch panel serving as an input device has a plurality of driving electrodes extending in an X-axis direction and arranged in a Y-axis direction intersecting with the X-axis direction, and a driving electrode arranged outside one side of an arrangement of the driving electrodes and extending in the X-axis direction. Further, the touch panel TP1 has a plurality of detecting electrodes extending in the Y-axis direction and arranged in the X-axis direction. The width of the driving electrode is smaller than the widths of the driving electrodes and the detecting electrode includes an expanding portion for expanding the area of the detecting electrode on the side opposite to the plurality of driving electrodes via the driving electrode.
