Abstract: Ghost image formation due to reflections of image light by a display panel to an ocular lens may be suppressed by ensuring that the image light reflected by the lens does not get reflected by the display panel back towards the lens. To that end, the display panel may include a quarter-wave birefringent layer between the top polarizer of the display panel and a layer inside the display panel that the image light reflects from, such as a black grid layer or an active matrix layer.
