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.

First claim

What is claimed is:

1. 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 electr…
