  • Patent number: 11435640
    Abstract: A cholesteric liquid crystal display includes a cholesteric liquid crystal device, a color filter element, a first quarter-wave plate, and a light recovery structure. The cholesteric liquid crystal device includes a cholesteric liquid crystal. The color filter element and the first quarter-wave plate overlap the cholesteric liquid crystal device. The first quarter-wave plate and the color filter element are located between the cholesteric liquid crystal and the light recovery structure.

  • Patent number: 11314138
    Abstract: The present invention provides a display device including a display panel having a display surface, a polarizer disposed on the display surface, a first phase retardation layer disposed on one side of the polarizer opposite to the display surface, a polymerized cholesteric material layer disposed on one side of the first phase retardation layer opposite to the display surface, a second phase retardation layer disposed on one side of the polymerized cholesteric material layer opposite to the display surface, and a switchable polarizer disposed on one side of the second phase retardation layer opposite to the display surface. A first optical axis of the first phase retardation layer is orthogonal to a second optical axis of the second phase retardation layer. A first absorption axis of the polarizer is in the same direction as a second absorption axis of the switchable polarizer.
