<P>PROBLEM TO BE SOLVED: To solve the problem of increase in the number of electrodes and poor implementability due to the small size negative electrode occurring in a block LED element composed of connected unit LED elements. <P>SOLUTION: In a unit LED element, exposed parts 17c, 17d of n-type semiconductor layers 17a, 17b exposed on p-type semiconductor layers 16a, 16b are located on the center part of the p-type semiconductor layers 16a, 16b and connected with a cathode bump electrode 12 formed on a second protection film 13, via negative electrode wiring 19. Similarly, the p-type semiconductor layers 16a, 16b are connected with an anode bump electrode 11 formed on the second protection film 13, via openings 15a-15d of a first protection film formed on four corners of the p-type semiconductor layers 16a, 16b and positive electrode wiring 14. <P>COPYRIGHT: (C)2012,JPO&INPIT |
