The invention provides a high-brightness thick-writing pressure-sensitive cholesteric phase liquid crystal chalkboard structure and a manufacturing process thereof; the high-brightness thick-writing pressure-sensitive cholesteric phase liquid crystal chalkboard structure comprises a transparent PET (polyethylene terephthalate) structural layer, an upper macromolecular polymer layer, first and second liquid crystal layers having different screw pitches, a lower macromolecular polymer layer and a lower PET layer; the transparent PET structural layer comprises an antifouling membrane layer, a hardened layer, a matt surface layer, a transparent PET layer, an anti-refection layer, an indium tin oxide conductive membrane layer, and a bonding layer arranged sequentially from top to bottom; the transparent PET layer or the indium tin oxide conductive membrane layer is thicker than the antifouling membrane layer, the hardened layer, the matt surface layer, the anti-reflection layer and the bonding layer. The high-brightness thick-writing pressure-sensitive cholesteric phase liquid crystal chalkboard structure allows writings to be cleared by one key, the structure is power efficient, the manufacturing process is simple, the cost is lower, and the whole manufacturing process is substantially automated and is environmentally friendly and energy efficient.
