<p>The present invention relates to a backlight unit for use in a liquid crystal display, and a liquid crystal display and a gaming machine comprising the same. The gaming machine includes a liquid crystal display having a liquid crystal panel and a backlight unit arranged behind the liquid crystal panel, and one or more reels on which a plurality of symbols are marked. The backlight unit includes a pair of transparent plates, a polymer dispersion type liquid crystal layer, and a light source module. The two transparent plates are opposed to one another, and the opposed surfaces thereof have corresponding, preset areas wherein respective transparent electrodes are arranged. The polymer dispersion type liquid crystal layer is disposed in the space formed between the pair of transparent plates. The light source module includes a frame in which an area corresponding to a preset area is empty or transparent, and a surface light source or a plurality of light sources arranged in the frame such that the surface light source(s) are disposed in the area corresponding to the areas of the transparent plates. In a case where voltage is applied to the transparent electrodes, the symbol selected from among the symbols on the reels is visible on the front of the gaming machine in a preset area. On the other hand, in a case where no voltage is applied to the transparent electrodes, the whole of the image display area of the liquid crystal display of the gaming machine can be used as a general liquid crystal display.</p> |
