Claim 8:
9. The display apparatus of claim 1, wherein the planar reflective surface of each of the plurality of sub-reflector structures comprises a preset point, a mirror point formed by an observation point in the first predetermined region relative to the transflective structure is a virtual image of the observation point, a mirror point formed by the preset point relative to the transflective structure is a virtual image of the preset point, and a center of a light emitting surface of the projector device is a light emitting point,
a normal line of the planar reflective surface is located at an angular bisector of a first connecting line, between the preset point and the light emitting point, and a second connecting line, between the preset point and the virtual image of the observation point; or
a connecting line between the observation point and the virtual image of the preset point intersects the transflective structure to have an intersection point with the transflective structure, and a normal line of the planar reflective surface is located at an angular bisector of a first connecting line, between the preset point and the light emitting point, and a third connecting line, between the preset point and the intersection point.
