GAN LED ELEMENT AND LIGHT EMITTING DEVICE HAVING A STRUCTURE TO REDUCE LIGHT ABSORPTION BY A PAD ELECTRODE INCLUDED THEREIN |
摘要 |
A first conductive film 104-1 of a light-transmissive conductive oxide film 104 and a positive pad electrode 105 are electrically connected through a second conductive film 104-2 of the light-transmissive conductive oxide film 104 in a GaN-based LED element 100. A contact resistance of the light-transmissive conductive oxide film 104 with a p-type layer 102-3 in a first contact portion 104A is lower than in a second contact portion 104B, so that a current supplied from the positive pad electrode 105 to the p-type layer 102-3 through the conductive oxide film 104 flows to the p-type layer 102-3 mainly through the first contact portion 104A. |
