Display device with a built-in touch panel

A display device with a built-in touch panel, comprising:

• a first substrate;
• a second substrate;
• a plurality of pixel electrodes provided between the first substrate and the second substrate;
• a plurality of common electrodes arranged next to each other with a space therebetween and provided between the first substrate and the second substrate;
• and
• a plurality of detection electrodes provided on the first substrate to face the respective common electrodes, wherein
• an image is displayed by light control using an electric field generated between the plurality of pixel electrodes and the plurality of common electrodes,
• presence or absence of a touch is detected by a difference in capacitance due to presence or absence of a material interrupting the electric field generated between one of the detection electrodes and one of the common electrodes, and
• each of the detection electrodes has through holes at positions facing a corresponding one of the common electrodes, avoiding a position above the space between common electrodes of the plurality of common electrodes that are next to each other.
