— A reflective‐type polarizer‐free flexible display using a dye‐doped liquid‐crystal (LC) gels is demonstrated. Compared to the conventional guest‐host LC mode, it has high contrast ratio and brightness due to the combining of both scattering and absorption. Such a gel‐like flexible display is bendable and trimable. In this paper, a three‐step switch using distinct dye‐doped LC gels is also demonstrated. The potential applications are e‐paper and decorative displays.
