Abstract
A touch electrode and a detection element are positioned in at least two of pixels. The touch electrode is formed in a first substrate, and is positioned so as to face a counter electrode. The touch electrode contacts the counter electrode and is electrically connected thereto when a second substrate is pressed and bent toward the first substrate. The detection element is connected to the touch electrode, and detects the electrical connection between the touch electrode and the counter electrode.
