Abstract: A viewing angle control film and a display device including the same are discussed. The viewing angle control film can include a first film including a first electrode, a second film facing the first film while being away from the first film by a predetermined distance and including a second electrode, a light conversion layer disposed between the first film and the second film, and an adhesive layer bonding the light conversion layer and the first film. The light conversion layer can include containing portions disposed at regular intervals along the first film between the first film and the second film, a louver layer surrounding the containing portions while spacing the containing portions and the second film, and light blocking particles provided in each of the containing portions.

Abstract: A selective transparent display device according to an embodiment can be operated in a transparent mode in which a background is transmitted, a clear mode in which the background is blocked, and a viewing angle control mode in which the background is blocked only at a specific viewing angle or within a specific viewing angle range depending on the usage environment. The selective transparent display device can include a transparent display panel configured to display images and an optical shutter disposed on a surface of the transparent display panel.
