Abstract
A display apparatus capable of image scanning is provided including a contact sensor arranged in each unit pixel. The contact sensor includes a pixel electrode forming a contact capacitance by contact with a contact means; a reset transistor where a drain electrode is connected to a node where the contact capacitance is formed, and each of a gate electrode and a source electrode is connected to a first scan line to which a selective signal is applied; an amplifying transistor where a gate electrode is connected to the drain electrode of the reset transistor; and a detecting transistor where a drain electrode is connected to the drain electrode of the amplifying transistor, a gate electrode is connected to a second scan line to which a selective signal is applied, and a source electrode is connected to a readout line detecting a current corresponding to the contact capacitance.
