Claim:
1. A transparent display device comprising: a first substrate including a pixel region and a light amount controlling region positioned so as to be in parallel to the pixel region; an organic light emitting display positioned in the pixel region on the first substrate and including an anode electrode, a pixel defined layer covering an edge of the anode electrode and including an opening part extending to a portion of the anode electrode, an organic light emitting layer positioned on the anode electrode and in the opening part, and a cathode electrode positioned on the organic light emitting layer; a liquid crystal display positioned in the light amount controlling region on the first substrate and including a pixel electrode, a roof layer facing the pixel electrode, and a liquid crystal layer having a plurality of microcavities partitioned from each other between the pixel electrode and the roof layer, wherein the microcavities comprise liquid crystal molecules; and a second substrate sealing the organic light emitting display and the liquid crystal display.
