Abstract: An organic light emitting display device may include a filling part filling a space between a second substrate and an organic light emitting diode, and a dam structure disposed in a non-display area and surrounding the filling part. At least one of the dam structure and the filling part includes a getter. The getter of the present disclosure is composed of magnesium oxide particles whose surfaces are modified into a first surface modification part made of an amino silane-based compound and a second surface modification part bound to the first surface modification part and made of a compound containing an acrylate group and a methacrylate group. Accordingly, it is possible to provide an organic light emitting display device that has high transparency and of which optical properties and durability are improved by minimizing permeation of water and oxygen.

Abstract: A display device includes a first backlight, a viewing angle control assembly disposed on the first backlight, a second backlight disposed on the viewing angle control assembly, and a display panel disposed on the second backlight. In a security mode, only the first backlight may be operable with the viewing angle control assembly having light blocking areas that limit light transmission to the display panel to within a predetermined range to limit a viewing angle of images displayed on the display panel. In a sharing mode, the second backlight is operated and the viewing angle control assembly does not limit light transmission, thus widening the viewing angle of images on the display panel. The display device may also include an anti-condensation layer on the second backlight to improve durability in high temperature and high humidity environments.
