  • Publication number: 20250013113
    Abstract: A display device including a substrate, a cholesteric liquid crystal layer, and a transparent electrode layer that are sequentially stacked is provided. The cholesteric liquid crystal layer includes cholesteric liquid crystal molecules and a plurality of transparent photoresist structures. Each of the transparent photoresist structures is a closed structure, and the cholesteric liquid crystal molecules are respectively accommodated in a plurality of patterned areas respectively surrounded by the transparent photoresist structures, so as to form a plurality of cholesteric liquid crystal patterns. The transparent electrode layer includes a plurality of sub-electrodes. The cholesteric liquid crystal patterns are respectively driven by the sub-electrodes. An orthogonal projection of each of the transparent photoresist structures on the substrate falls in an orthogonal projection of a corresponding sub-electrode of the sub-electrodes on the substrate.
