Abstract: The present disclosure includes: a display panel separated into a light emitting unit, in which an organic light emitting diode is disposed, and a light transmitting unit which selectively transmits light; and a driving circuit configured to drive the display panel. The display panel includes a first substrate, a second substrate, and a liquid crystal layer. In the first substrate, the organic light emitting diode is disposed in the light emitting unit, and a first electrode is disposed in the light transmitting unit. The second substrate faces the first substrate, and a second electrode is disposed in the light transmitting unit. The liquid crystal layer is interposed between the first electrode and the second electrode, and adjusts a transmittance due to a difference between a voltage applied to the first electrode and a voltage applied to the second electrode.
