A display device include a first transparent layer, a second transparent layer and a spacer arranged between the first transparent layer and the second transparent layer to define a first region and a second region. A first plurality of electrodes are arranged on an inner surface of the first transparent layer in the first region. A plurality of light emitting diodes (LEDs) are connected to the first plurality of electrodes in the first region. A second plurality of electrodes are arranged on the inner surface of the first transparent layer in the second region. A third plurality of electrodes are arranged on the inner surface of the second transparent layer in the second region. Particles are arranged in the second region between the second plurality of electrodes and the third plurality of electrodes.
