A display region has a curved surface shape having upper and lower end portions disposed at positions closer to a visual field than a reference plane, and a central portion disposed at a position farther from the visual field than the reference plane. A first convergence angle difference between a convergence angle from the eye position to the upper end portion and a convergence angle from the eye position to a first point on the reference plane through the upper end portion, a second convergence angle difference between a convergence angle to the central portion and a convergence angle to a second point on the reference plane through the central portion, and a third convergence angle difference between a convergence angle to the lower end portion and a convergence angle to a third point on the reference plane through the lower end portion respectively fall within four milliradians.
