Abstract: A display couples a display panel over a light guide plate in a sharp edge housing by adapting the light guide plate side to have a beveled surface that fits along its perimeter into a reduced depth of the housing. The light guide plate beveled surface has angled sides relative to the light guide plate illumination side and reflective side to fit against parallel sides formed in the housing as the housing narrows towards its base where the light guide plate couples. A diffusive pattern formed in the light guide plate reflective surface that directs light towards the illumination surface extends onto the light guide plate side beveled surface.
