A reflective display device includes a pixel structure (200) and a liquid crystal (210) containing a dye. The pixel structure (200) provides the liquid crystal (210) with a first tilt state and a second tilt state that are stable absent application of an electric field. In the first tilt state, the liquid crystal (210) is in an untwisted configuration. In the second tilt state, the liquid crystal (210) is in a twisted configuration, and the dye has an effective absorption that is higher than an effective absorption of the dye when the liquid crystal (210) is in the first tilt state.
