主权项

1. A display device comprising:
a display portion partitioned into a plurality of cells configured to select and maintain one of a transparent state or a reflective state as a display state in accordance with a voltage applied thereto, such that the cells are configured to (i) select and maintain the transparent state when a first voltage is applied thereto and (ii) select and maintain the reflective state when a second voltage is applied thereto; and a plurality of light transmission regions adjacent to the cells and at positions corresponding to a plurality of light sources arranged over the display portion so as to be in-line therewith in a thickness direction which is perpendicular to a display surface of the display portion, such that a respective one of the light transmission regions is arranged adjacent to a number of respective cells and at a respective position which corresponds to a respective light source so as to be in-line with the respective light source in the thickness direction, in which the display portion has a viewer side associated therewith from which a viewer is able to view an image during operation, in which each of the cells includes a corresponding display part such that the plurality of cells has a plurality of display parts, and the display parts enable a still image, text or pattern to be displayed thereon when the light sources are not actively emitting light, and in which the transparent state corresponds to an ON-state with light actively emitted from the light sources and the reflective state corresponds to an OFF-state with light not actively emitted from the light sources such that when the cells are in the transparent state emitted light from the plurality of light sources is allowed to pass through the light transmission regions so as to be seen by the viewer from the viewer side, and when the cells are in the reflective state light is not emitted from the plurality of light sources and the still image, text or pattern is caused to be displayed on the display parts of the cells by reflection of ambient light on the display parts so as to be seen by the viewer from the same viewer side.
