Light emitting device with improved light extraction efficiency |
摘要 |
A light emitting device having a high degree of light extraction efficiency includes a substrate, and a light emitting structure disposed on one surface of the substrate, the substrate having an internal reformed region where the index of refraction differs from the remainder the substrate. The ratio of the depth of the reformed region (distance between the other surface of the substrate and the reformed region) to the thickness of the substrate is in a range of between 1/8 and 9/11. |
