Abstract: A display device includes an array substrate and a counter substrate. The array substrate includes an outgoing line for connecting a first electrode for capacitive touch detection to a detection circuit. The outgoing line includes: a first wiring portion extended from the first electrode side to the detection circuit side; and a first capacitance adjusting wiring portion connected to the first wiring portion on the same layer and serving to adjust the total capacitance of the first electrode and the outgoing line.

Abstract: A technique capable of reducing the number of leading lines and making the area of a frame region smaller is provided. A display device includes an in-cell touch panel in which a pair of transparent substrates is arranged so as to oppose each other, a plurality of scanning electrodes are disposed on an opposing surface of one of the transparent substrates, and detection electrodes that intersect with the scanning electrodes are arranged on an opposing surface of the other transparent substrate. The display device further includes at least one first leading lines electrically connected the scanning electrodes and configured to supply a scanning signal to the scanning electrodes, and at least one second leading lines electrically connected to the detection electrodes and configured to output a signal detected by the detection electrodes. In the display device, each of the first leading lines is connected to at least two of the scanning electrodes having different widths.

Abstract: A display device with a built-in touch panel includes a first substrate, a second substrate, plural pixel electrodes provided between the first substrate and the second substrate, plural common electrodes provided between the first substrate and the second substrate, and plural detection electrodes provided on the first substrate. An image is displayed by, light control using an electric field generated between the plural pixel electrodes and the plural common electrodes. The presence or absence of touch is detected by a difference in capacitance due to the presence or absence of a material interrupting the electric field generated between one of the detection electrodes and one of the common electrodes. Each of the detection electrodes includes a through hole.

Abstract: A display device includes lead lines that extend from a display area, and electrically connect video signal lines or scanning signal lines within a display area, and a driver circuit or a terminal portion that receives an output from the driver circuit; an insulating film that is formed in an upper layer of the lead lines and covers the lead lines; and a conductive film that is formed in an upper layer of the insulating film. The lead lines include a plurality of first lead lines that start from the driver circuit or the terminal portion, and arrive at the scanning signal lines or the video signal lines, and a plurality of second lead lines that are smaller in wiring resistance than the first lead lines. At least the first lead lines overlap with the conductive film through the insulating film.
