摘要： According to one embodiment, a display apparatus includes an image projection unit, an information acquisition unit and a data supply unit. The image projection unit projects a light flux including an image toward a projection layer which is reflective and transmissive. The information acquisition unit acquires information relating to a position of a three-dimensional object superimposing portion of three-dimensional objects positioned at a road. The road extends from a proximal region of the external environment proximal to the projection layer toward a distal region of the external environment distal to the projection layer. The three-dimensional object superimposing portion is higher than a ground surface and viewable via the projection layer. The data supply unit supplies data relating to the image including a display object to the image projection unit based on the information. The display object is displayed along the three-dimensional object superimposing portion.
