Abstract: A head mounted display includes a first display element and a second display element that emit light to a second portion. A first portion includes a first opening and a second opening separating from the first opening. The second portion includes a first optical element portion facing the first opening in a first direction and a second optical element portion facing the second opening in the first direction. Each of the first optical element portion and the second optical element portion of the second portion includes a reflection portion reflecting light emitted from the first display element or the second display element and a light-transmittance adjustment portion controlling a transmittance of external light travelling from the second portion toward the first portion on the basis of a signal that is output from a light-transmittance control circuit. The reflection portion is arranged between the light-transmittance adjustment portion and the first portion.
