An eyepiece for a head mounted display, comprising: a display panel for generating display light ; and an eyepiece body , including: an input lens positioned to couple the display light into the eyepiece body along a forward propagation path; a concave end reflector disposed at an opposite end of the eyepiece body from the input lens to reflect the display light back along a reverse propagation path within the eyepiece body; and a viewing region disposed between the input lens and the concave end reflector and including a partially reflective surface , the partially reflective surface to redirect at least a portion of the display light traveling along the reverse propagation path out of an eye-ward side of the eyepiece body along an emission path, wherein the partially reflective surface is obliquely angled with an offset from 45 degrees relative to the eye-ward side and the concave end reflector is titled relative to a top or bottom surface of the eyepiece body to collectively cause the emission path of the display light to be oblique to a first normal vector of the eye-ward side in a vertical direction and a horizontal dimension, wherein the input lens is tilted such that a second normal vector from a center point of the input lens is obliquely angled relative to the top or bottom surface of the eyepiece body and obliquely intersects the display panel in at least one dimension, thereby to introduce chromatic compensation to offset chromatic distortion introduced by the tilt angle of the concave end reflector. a display panel for generating display light ; and an eyepiece body , including: an input lens positioned to couple the display light into the eyepiece body along a forward propagation path; a concave end reflector disposed at an opposite end of the eyepiece body from the input lens to reflect the display light back along a reverse propagation path within the eyepiece body; and a viewing region disposed between the input lens and the concave end reflector and including a partially reflective surface , the partially reflective surface to redirect at least a portion of the display light traveling along the reverse propagation path out of an eye-ward side of the eyepiece body along an emission path, an input lens positioned to couple the display light into the eyepiece body along a forward propagation path; a concave end reflector disposed at an opposite end of the eyepiece body from the input lens to reflect the display light back along a reverse propagation path within the eyepiece body; and a viewing region disposed between the input lens and the concave end reflector and including a partially reflective surface , the partially reflective surface to redirect at least a portion of the display light traveling along the reverse propagation path out of an eye-ward side of the eyepiece body along an emission path, wherein the partially reflective surface is obliquely angled with an offset from 45 degrees relative to the eye-ward side and the concave end reflector is titled relative to a top or bottom surface of the eyepiece body to collectively cause the emission path of the display light to be oblique to a first normal vector of the eye-ward side in a vertical direction and a horizontal dimension, wherein the input lens is tilted such that a second normal vector from a center point of the input lens is obliquely angled relative to the top or bottom surface of the eyepiece body and obliquely intersects the display panel in at least one dimension, thereby to introduce chromatic compensation to offset chromatic distortion introduced by the tilt angle of the concave end reflector. <EOS>
