Abstract
In this work, we propose a normally transparent polymer‐networked liquid crystal (PNLC) mode to use as a transparent display with energy saving, high contrast ratio, easy manufacturing process (Polyimide‐free). In this system, we adopt a homeotropic alignment material (HAM), which serves as both vertical alignment inducer and photopolymerizable reactive mesogen (RM). With no polarizers, the ground state shows clear transparency, and applying voltage induces an opaque scattering state successfully. By using double‐sided UV irradiation strategy, we can minimize hysteresis on voltage‐dependent transmittance. we believe the proposed concept will open a way to reach a novel transparent display with high transparency.
