PURPOSE: An illumination source is provided to use the light(multi light source or large light source) inputted without a loss by being connected to an edge of a wave guide through a connection structure grown smaller from a light source with the size of the edge of the wave guide. CONSTITUTION: An illumination source(10) includes an array having one or more of a light source(30) such as an applicable planar source for inserting an emitting diode(LED), a flat fluorescent lamp, a light source or a high reflection rate of a dispersion material into a substrate. The illumination source(10) is connected to a wave guide of two illuminations(10) near the wave guide(50). The light source(30) is in the range from 10% to 70% to the ratio of a total area of the substrate(40). Also, The light source is equipped on a proper surface by being separated to obtain a brightness wanted like a glass fiber board coated with copper.
