Abstract
A three-dimensional display device includes a plurality of transmissive display units arranged in different depth positions in view from an observer and a moiré vanishing element for diffusing light. The moiré vanishing element has a spatial frequency characteristic to cut off a spatial frequency more than a spatial frequency having a cycle being twice as large as an interval of boundaries of pixels forming a first transmissive display unit arranged behind the moiré vanishing element in the view from the observer.
