We present rigid/soft/rigid (RSR) type cover window for the foldable display. We investigated the synthesis of flexible nanosol through sol‐gel reaction and fabricated RSR cover window sample with a home‐made slot die coater. Furthermore, coating thickness uniformity, surface hardness, folding reliability were explored.
