Abstract

The application discloses a reflective display device and display equipment, which relate to display technology. The device includes a display unit arranged between an upper transparent substrate and a lower substrate. The display unit includes an electrode, a refraction deformation component, and a black absorbing layer. Wherein, the refraction deformation component is deformed under the action of the electrode to switch between the first state and the second state. In the first state, the refraction deformation component completely reflects the incident light incident through the upper transparent substrate to form a bright state, and in the second state In the state, the incident light passes through the refraction deformation component and is absorbed by the black absorbing layer to form a dark state. Since the display device does not include particles, there is no particle agglomeration or uneven distribution affecting the display performance, and no nanoimprinting process and arc-shaped electrodes are required, so the process difficulty is relatively low.
