Abstract
A display apparatus includes an image display element, an eyepiece portion, an object window, and a reflection optical element disposed at a position between the eyepiece portion and the object window, the reflection optical element being configured to guide a picture displayed on the image display element to the eyepiece portion. The reflection optical element changes a state to a first state and a second state by changing a transmittance. In the first state, the picture displayed on the image display element is viewed via the eyepiece portion. In the second state, an image in which an image from the object window and an image displayed on the image display element are superimposed is viewed via the eyepiece portion.
