Abstract Tunable metasurfaces for beam‐splitting hold potential applications in optical computing, communication, and sensing. However, existing approaches have been demonstrated mostly gigahertz (GHz) terahertz (THz) frequency ranges due to the limited scalability of current nanofabrication techniques scarcity suitable materials efficient visible spectrum. In this work, an electrically tunable metasurface is introduced by combining liquid crystal (LC) cells with a titanium dioxide particle‐embedded resin (TiO 2 ‐PER), scalable, high‐refractive‐index, low‐loss material designed mass production. By integrating LC broadband gradient metasurface, dynamic beam splitting achieved through real‐time polarization switching within under applied electric fields. Nanoimprint lithography (NIL) TiO ‐PER, supported established display (LCD) industry technologies, enables scalable cost‐effective manufacturing, providing practical solution next‐generation devices that integrate electronic photonic signals.
