Abstract: A transparent display device includes a first substrate including a pixel region and a light amount controlling region. An organic light emitting display is positioned in the pixel region and includes an anode electrode, a pixel defined layer, an organic light emitting layer positioned on the anode electrode and in an opening part of the pixel defined layer, and a cathode electrode positioned on the organic light emitting layer. A liquid crystal display is positioned in the light amount controlling region and includes a pixel electrode, a roof layer facing the pixel electrode, and a liquid crystal layer having a plurality of microcavities between the pixel electrode and the roof layer. The microcavities include liquid crystal molecules. A second substrate seals the organic light emitting display and the liquid crystal display.

Abstract: An optical member includes a light guide plate in which light incident thereto is propagated, including: an emission surface through which propagated light exits the light guide plate, a light incident side surface through which the light is incident to the light guide plate, and an inclined edge surface connecting the emission and light incident side surfaces to each other; and a wavelength conversion layer to which exited light from the light guide plate is incident and which converts a wavelength of the exited light, disposed facing the emission surface of the light guide plate. The inclined edge surface and emission surfaces define a boundary therebetween, and a side surface of the wavelength conversion layer which is closest to the light incident side surface is further from the light incident side surface than the boundary between the inclined edge surface and the emission surface.
