The above object, according to the present invention, includes a flexible sheet, a plurality of LED lamps fixedly arranged as appropriate on the surface of the sheet, a transparent sheet arranged on the front side of the sheet, and a transparent sheet arranged on the front side of the sheet. A protective cover consisting of a waterproof sheet disposed on the back side and formed to surround the sheet, and a protective cover connected to each LED lamp by passing between the sheet and the waterproof sheet to light the LED lamps. The exposed part of each LED lamp on the back side of the sheet is covered by a protective hood that is engaged with the back side of the LED lamp, and the back side of this protective hood is covered with the above-mentioned waterproof circuit. This is achieved by an LED display type sign device configured on the surface of the sheet and whose front side is adhered to the back side of the sheet.

According to this invention, since the entire device basically consists of a flexible sheet and a protective cover, it is possible to attach this sheet to a curved surface during use, and when not in use. They can sometimes be folded or rolled up, making them easier to carry and requiring less space for storage. Moreover, since a predetermined pattern is emitted and displayed using LED lamps, the visibility of the display is greatly improved, thereby improving safety.

Furthermore, since the connection lead wires to each LED lamp are protected by a waterproof sheet and fixedly held by a protective hood on the back side of the LED lamp, the protective cover etc. will not touch the back side of the LED lamp during use. Even if the LED lamp is scratched or scratched, the connection lead wires on the back side of the LED lamp will not be cut and are protected by the holding hood.
