A compact head-mountable display device for transmitting an image to a user's eye is provided. The display device includes a support fixture comprising an elongated member (10) configured to allow passage of ambient light (44) across a direction of elongation of the elongated member (10) to a user's eye. A display (20), such as an LCD, is supported by the support (10) and is operative to provide an image. An eyepiece assembly (40) is supported by the support fixture (10) in proximity to the display (20) to receive the image from the display and to direct the image to the user's eye. The support fixture also defines an illumination path (4) along the elongated member (10), and the display (20) is located to receive illumination light on the illumination path (43) from a light source (12).
