Display device with touch sensor, and electronic apparatus

摘要

According to an aspect, a display device with a touch sensor has a display function and a touch sensor function. The display device includes: a panel unit that comprises a first substrate, a second substrate, and a display function layer between the first substrate and the second substrate; a first electrode on the first substrate; a second electrode on the second substrate; a third electrode on the second substrate; and a capacitor for the touch sensor function. The capacitor is formed between either of the first electrode and the second electrode and the third electrode, or between both the first electrode and the second electrode and the third electrode. The frame portion outside the display area comprises, on the first substrate side thereof, a peripheral circuit, and the second electrode is provided in a position more distant upward from the peripheral circuit than the first electrode.

1. A display device with a touch sensor having a display function and a touch sensor function, the display device comprising:
a panel unit that comprises a first substrate, a second substrate, and a display function layer between the first substrate and the second substrate; a first electrode on the first substrate having a function as a first touch drive electrode that constitutes the touch sensor function; a second electrode on the second substrate having a function as a second touch drive electrode that constitutes the touch sensor function; a third electrode on the second substrate having a function as a touch detection electrode that constitutes the touch sensor function; and a capacitor for the touch sensor function, the capacitor being formed between either of the first electrode and the second electrode and the third electrode, or between both the first electrode and the second electrode and the third electrode; wherein when the touch sensor function is used, a first signal is applied to the first electrode and the second electrode, and a second signal is detected from the third electrode through the capacitor; the first electrode of the first substrate is disposed in a display area of the panel unit, and the second electrode of the second substrate is disposed in a frame portion outside the display area, and the first electrode and the second electrode are connected to each other by an upper/lower conducting portion provided at the frame portion; and the frame portion comprises, on the first substrate thereof, a peripheral circuit, and the second electrode is provided in a position more distant upward from the peripheral circuit than the first electrode.
