Abstract
A reflection type display device and a display apparatus are provided. The reflection type display device includes: an upper transparent substrate, a lower substrate, and a display unit provided between the upper transparent substrate and the lower substrate. The display unit includes an electrode, a refractive deformation member and a black absorption layer. The refractive deformation member is configured to deform under control of the electrode to switch between a first state and a second state. In the first state, incident light through the upper transparent substrate is totally reflected by the refractive deformation member to form a bright state; and in the second state, incident light passes through the refractive deformation member and is absorbed by the black absorption layer to form a dark state.
