Aspects of the disclosed apparatuses, methods, and systems provide enhanced display of images for personal wearable display devices. The display systems include various system components to implement one or more of: re-directing the maximal brightness of a display device towards the center of the eye-box of a user; selectively narrowing the viewing angle of light emitted by the display device; and by spatially optimizing the backlight of the display device based on the specification of the wearable optical system thereby optimizing and/or maximizing the amount of light entering the eye for a range of gaze rotation of a user of the wearable display system. In one example, the following description provides a display device including a light optimizing or directing layer. The light optimizing layer includes one or more films that optimize the amount of light directed to the eye box of a user of the wearable display system. The light optimizing layer may include one or more films positioned to direct light from the image source and illumination source in a desired manner.
