1. An organic electroluminescent display device, comprising:
- an image displaying part comprising a plurality of pixels to display an image corresponding to a data signal and a selection signal, with the displayed image being available for viewing from both sides of the image displaying part;
an optical shutter provided on at least one of the sides of the image displaying part to transmit and block light in response to a control signal;
a sensor transmitting a sensed signal representative of a detection by the sensor of an on-state of a front side of the image displaying part and a detection by the sensor of an on-state of a back side of the image displaying part; and
a driver circuit responding to the sensed signal by supplying the data and selection signals to the plurality of pixels and the control signal to the optical shutter.

Abstract
A double-sided organic electroluminescent display is constructed with an optical shutter. The organic electroluminescent display which includes an image displaying part comprising a plurality of pixels to display an image corresponding to a data signal and a selection signal, an optical shutter provided on the image displaying part to transmit or block light in response to a control signal, and a driver circuit to supply the data and selection signals to the plurality of pixels and the control signal to the optical shutter, respectively is excellent in visual recognition.
