Abstract
A display device includes a display device a display panel (e.g. a blackboard or a whiteboard) juxtaposed in a frame. The rear face of the display device is covered by a cover having a height and a planar part. It is possible to selectively attach a reversible I/O unit and a reversible option slot unit to either the right side end or the left side end in the planar part of the rear face of the display device in such a way that input/output terminals are directed to the exterior of the display device. Additionally, an air outlet and an air inlet are formed in the surface of the option slot unit opposite to the rear face joining the planar part of the rear face of the display, thus securing air ventilation. The display device having user friendliness can be easily manufactured using standardized parts with a low manufacturing cost.
