  • Patent number: 8508698
    Abstract: A dual view display structure and a method for producing the same are provided. First, a display panel is provided. Then, a patterned barrier layer is formed on a transparent substrate. The transparent substrate with the patterned barrier layer is attached to the display panel. Because there is a gap between the display panel and the patterned barrier layer, a liquid transparent material is injected into the gap to form a transparent material layer to fill the gap. The invention can not only increase the viewing angles of the dual view display, but also increase the production yield.
