Abstract:
     A two-way communication device having a display device of novel structure and an image pickup device is provided. More particularly, a two-way communication system having a display device and an image pickup device is provided. The display device having an image pickup function includes an image pickup unit and a display panel in which light emitting elements which can transmit visible light at least and be controlled by voltage or current are arranged. A compact and lightweight device can be achieved without using a complicated optical system or an optical system having a long light path, whereby two parties can communicate while catching each other's eyes.
