An outdoor display device includes road guide display plates or road mark plates disposed on the road side or on the road while they are supported by a supporting member such as a support column, a pole, a mounting beam or the like. Additive display portions each having a suitable size are attached to the rear surface side or the lateral side of the latter of the load guide display plates or the load mark plates. A plurality of light emitting members such as LEDs or miniature bulbs are arranged on the whole surface of each additive display portion in the planar relationship. A pattern of turning on or intermittently turning on the light emitting members is controlled in such a manner that characters, figures or marks are combined with each other to define a certain content to be displayed.
