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.

Display device

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.

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.

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.

An illuminating device includes: a light source; a light guide plate which converts light emitted from the light source into a surface light ray and emits the surface light ray through a front surface of the light guide plate; and an optical sheet which changes a propagation direction of the surface light ray emitted from the light guide plate. The light source is arranged in opposition to one end surface of the light guide plate. A polarization state converting structure to convert a polarization state of the light propagating through the light guide plate is provided in a rear surface of the light guide plate. The polarization state converting structure contains an inclination plane having a ridge line extending in a direction perpendicular to the extension direction of the one end surface.

Disclosed is a touch panel-equipped display device capable of suppressing an increase in the number of wires and improving detection resolution. A touch panel-equipped display device includes scanning lines and detection lines. The detection lines include first main detection lines, second main detection lines, first one-side sub-detection lines, and first other-side sub-detection lines. Each of the second main detection lines is arranged between adjacent first main detection lines. The first one-side sub-detection lines are connected together, and each first one-side sub-detection lines is arranged between the corresponding first main detection line and the second main detection line adjacent to one side of the corresponding first main detection line. The first other-side sub-detection lines are connected together, and each first other-side sub-detection lines is arranged between the corresponding first main detection lines and the second main detection line adjacent to the other side of the corresponding first main detection line.
