An illumination panel for the enhancement of image brightness of a liquid crystal display for a watch or similar device is disclosed. The panel has an internal light source with a suitably shaped and reflectorized coating to substantially direct internal and external light in the desired direction. More particularly, a transparent layer or member with an internal light source mounted at one end is selectively coated with a metallic reflecting material to reflect light from the internal source and from external sources through a crosshatched surface or a matte finished window on the surface of the member. The window may be defined by the reflectorized coating. The member is mounted adjacent to the exterior surface of the bottom substrate of the liquid crystal display. Diffused light is transmitted from the internal light source of the illumination panel through the bottom substrate of the display.
