In order to use the light emitting diode package 10 in an advertisement board, the light emitting diode packages connected to each other according to a letter or shape to be expressed must be cut to an appropriate length, and the wirings are cut again. In particular, when the light emitting diode package is used for an advertisement board or an electric signboard, the positive electrode wire 15a and the negative electrode wire 15b are coupled to the light emitting diode package 10 in consideration of being used for outdoor use. When the light emitting diode package cut in the middle wiring or when connecting again with other packages, the waterproofing process must be performed separately, and when the complicated shape is expressed, the wiring work is very complicated and time consuming.

FIG. 1B illustrates an example of representing T using the light emitting diode package shown in FIG. 1A. In order to express T, it is necessary to cut off the intermediate connection of the LED packages in a row and to connect the wires again at the intersection portion A of the series of LED packages. In addition, when any one of the LED package is broken or the end of life, it is time-consuming and very inconvenient to disconnect and reconnect the intermediate wiring during the replacement operation. In addition, each time the size or shape of the letter is changed, the wiring method of the module is different, so that the shape or size of the letter is determined, and then the module has to be manufactured to be suitable for the shape.
