Abstract:
A head-up display includes a display device and a projection optical system. The projection optical system has a lens group including at least one lens element and projects onto a reflecting member an image displayed on the display device. The lens group includes a drive lens that shifts along an optical path to change its distance from the display device.

Claim (Index 4):
The image projector according to  claim 1  or  2 , wherein:\n an incident surface of the drive lens is a surface on the display device, and an emission surface of the drive lens is a surface opposite to incident surface of the drive lens along the reference beam; and \n with a point of intersection of the reference beam and the incident surface being regarded as an origin, \n with a beam that reaches a center of the eyepoint region of the viewer and reaches an outer edge of a vehicle of the virtual image being regarded as a reference outer beam, \n with a straight line that includes the origin and a point of intersection of the reference outer beam and a tangent plane to the incident surface at the origin, being regarded as an X-axis, and \n with a direction perpendicular to the X-axis on the tangent plane being regarded as a Y-axis, \n the incident surface concavely faces the display device along the X-axis; and\n the incident surface has a smaller curvature along the Y-axis than along the X-axis.
