    Patent number: 5379182
    Abstract: A display panel and an information machine including the display panel, include a display panel unit having a display screen, and an inner cover for covering the inside of the display panel unit. A pair of metal fittings are screwed to side end portions of the display panel unit. In addition, an outer cover is provided for covering the outside of the display panel unit, where the outer cover and the display panel unit are both separately connected to the inner cover, so that the outer cover can be removed while leaving the display panel unit attached to the inner cover. Since the entire back surface of the display panel unit is exposed merely by removing the outer cover, the inspection and repair of the display panel unit is facilitated.
