Abstract
A light-emitting device operating on a high drive voltage and a small drive current. LEDs () are two-dimensionally formed on an insulating substrate () of e.g., sapphire monolithically and connected in series to form an LED array. Two such LED arrays are connected to electrodes () in inverse parallel. Air-bridge wiring () is formed between the LEDs () and between the LEDs () and electrodes (). The LED arrays are arranged zigzag to form a plurality of LEDs () to produce a high drive voltage and a small drive current. Two LED arrays are connected in inverse parallel, and therefore an AC power supply can be used as the power supply.
