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.

According to one embodiment, a display device includes an image projection unit. The image projection unit is configured to project a light flux toward one eye of a human viewer by using a projection plate to reflect the light flux. The light flux includes an image including a display object having a vanishing point. The projection plate is reflective and transmissive. The image projection unit is configured to dispose the vanishing point of the display object at a position different from a position of a vanishing point of a background image viewed by the human viewer through the projection plate.

According to one embodiment, a display device includes an image projection unit, an optical unit and a mounting unit. The image projection unit emits an image light. The optical unit includes a first optical layer having first and second major surfaces, a second optical layer having third and fourth major surfaces and an intermediate layer provided between the second and third major surfaces. At least a portion of the image light travelling from the first major surface toward the second major surface is reflected by the intermediate layer. At least a portion of a background light travelling from the fourth major surface toward the third major surface is transmitted by the intermediate layer. The first major surface or the fourth major surface is a curved surface. The mounting unit is linked to the image projection unit and the optical unit.
