TOUCH SENSOR DEVICE AND DISPLAY DEVICE WITH A TOUCH SENSOR
A display device with a touch sensor having a display function and a touch sensor function is provided. The display device includes a first substrate including a pixel electrode; a first electrode along a first direction; and a second substrate including a second electrode that includes patterns of electrodes along a second direction crossing the first direction and that faces the first electrode and the pixel electrode, wherein upon the display function being activated, the pixel electrode is supplied with a pixel signal, and the second electrode is supplied with common voltage, and upon the touch sensor function being activated, the first electrode is applied with a first signal and the second electrode is configured to receive the first signal to be a second signal as a touch detecting signal.
1 . A touch sensor device comprising:
a substrate; and
first electrodes arranged in a first layer on the substrate,
wherein at least one of the first electrodes comprising:
a first concave shape with a bottom;
a first portion and a second portion that sandwich the bottom; and
a third portion that is located between the first portion and the second portion and that is in contact with a whole of the bottom,
the first portion has a first width in a direction in which the first concave shape dents,
the third portion has a second width in the direction, and
the first width is wider than the second width.
