Abstract: Abstract The invention of the blue light-emitting diode (LED) by Isamu Akasaki, Hiroshi Amano and Shuji Nakamura is the breakthrough for LED technology. Since then, LED has attracted wide attention from researchers who further investigate the performance of this technology. This study aims to identify research trends and determine future research on the LED using bibliometrics and network analysis. The scientific impact of the journal articles has also been examined using citation counts. A total of 16,283 articles published in the Web of Science database from 2003 to 2018 were retrieved. We distinguish the most important articles, authors, journals, research organisations and countries in this research field. Over the period, the number of publications per year increased steadily, with the highest research output being 1,746 articles published in 2018. Approximately 42% of total publications on LED research come from the physics research area. Applied Physics Letters, Organic Electronics and IEEE Photonics Technology Letters are the top three journals with the most publications in this field. Chinese Academy of Sciences, National Taiwan University and National Chiao Tung University are the leading organisations based on the total number of publications. China (25.50%), South Korea (16.88%) and USA (14.40%) have high productivity in total publications.
