We demonstrate a single‐pixel color display based on voltage‐stretchable liquid crystal (LC) droplet. The gray scale is induced by stretching a dye‐doped LC droplet from a small circular visible area to different extent through dielectrophoretic force. This polarization‐insensitive liquid display shows a relatively low operating voltage, fast response, wide viewing angle and good contrast ratio. Both transmissive and reflective modes can be configured.
