Abstract
Disclosed is a display apparatus. The display apparatus comprises a display and a field-induced visibility-controlling layer provided on light-outgoing side of the display, wherein the field-induced visibility-controlling layer can be switched between a transparent state and a mirror state by adjusting voltage applied, such that when the field-induced visibility-controlling layer is in the transparent state, the display is visible through the field-induced visibility-controlling layer; and when the field-induced visibility-controlling layer is in the mirror state, a mirror shielding the display is formed therein.
