Abstract
A structure of a light emitting diode (LED) and a method of making the same are disclosed. The present invention is suitable for the light emitting diode having the area that is larger than 100 mil and having the insulating substrate, and is featured in that the P electrode and the N electrode are mutually intercrossed. With the use of the present invention, the light emitted by each individual unit chip is more even; the operating voltage of the device is reduced; the cut size of the device can be enlarged arbitrarily according to the size of the unit chip; and the light emitting efficiency is increased.
