Switchable optical element and switchable display device

Abstract

A switchable optical element including a first substrate, a second substrate, a switching medium, multiple lenses, and multiple spacers is provided. The second substrate is opposite to the first substrate. The switching medium is disposed between the first substrate and the second substrate. The lenses are disposed on the second substrate. The spacers are disposed between the lenses and the first substrate. In a cross-sectional direction of the switchable optical element, at least one of the spacers is disposed corresponding to at least one of the lenses. A switchable display device is also provided.
