Abstract: An organic light emitting display device includes a substrate, a lower electrode, a light emitting layer, an upper electrode, and a light guide structure. The substrate includes a sub-pixel region and a transparent region. The lower electrode is disposed in the sub-pixel region on the substrate. The light emitting layer is disposed on the lower electrode, and includes an organic emission layer. The upper electrode is disposed on the light emitting layer. The light guide structure is disposed on the upper electrode, and partially overlaps the organic emission layer that is located at the sub-pixel region and the substrate that is located at the transparent region in a plan view.

Abstract: A watch may include a first display unit, a second display unit, a first polarizer set, and a second polarizer set. The second display unit may be positioned over the first display unit and may transmit light. One of the first display unit and the second display unit may display a time information image that indicates time. The other of the first display unit and the second display unit may display non-time information image, e.g., a user interface element. The first polarizer set may be positioned between the first display unit and the second display unit. The second polarizer set may be positioned on the second display unit. One of the first polarizer set and the second polarizer set may rotate relative to the other for enabling the watch to conceal or show the time information image.
