Lee Dong Youb received his B.s. and M.A. from Hong-Ik University. He is one of the most important founders of a Korean abstract painting movement, Dansaekhwa. He participated in a group show entitled Five Korean Artists, Five Kinds of White held in Tokyo Gallery in May 1975, which is often credited as an exhibition that introduced Dansaekhwa for the first time.
Lee Dong Youb created white surface Dansaekhwa paintings for over fifty years until his death. The color white is a void for consciousness and a vessel for thought. From 1980s, the artist began the Between series with wide white brushstrokes on white backgrounds. This gesture made the paintings to generate and capture the natural overlap and the soaking of color. The artist repeated countless strokes to exclude materiality and realize spirituality like a truth-seeker. His white canvas reminds the viewer to fill the work with thought and interpretation.
Lee Dong Youb marked his achievements in Korean modern art history by participating in many significant exhibitions, including the 1st Independent Exhibition and his artwork is a part of public collections at Tokyo National Museum of Modern Art, Tokyo, The National Museum of Contemporary Art, Gwacheon, Korea.
