Daesung was born in Itaewon and attended high school at Kyeongin High School, but dropped out after a year to focus on his activities with Big Bang. Eventually, he passed his college entrance exams in 2008 and got admitted into the post-modern music department at Kyung Hee University in 2008.
Although his parents were strongly against the idea of him becoming a singer, Daesung pursued a singing career and was eventually recruited by YG Entertainment after auditioning. He later appeared on a reality show which documented the formation of Big Bang with five other trainees: G-Dragon, T.O.P, Taeyang, Seungri, and So-1 (Hyunseung). Hyunseung was eventually dropped and Big Bang debuted in 2006 with five members. Big Bang made their first appearance as a group on August 19, 2006, at YG Family's 10th Anniversary concert. On September 23, 2006, they had their debut performance on television broadcast.

Daesung also recorded his first solo song "Try Smiling" (Korean: 웃어본다; Revised Romanization: Useo Bonda) for Big Bang's first album Since 2007. The group's breakthrough came with the release of their first extended play, Always (2007), which included the number one song "Lies" (Korean: 거짓말; Revised Romanization: Geojitmal).

Their following EPs followed its predecessor's footsteps: Hot Issue yielded "Last Farewell" (Korean: 마지막 인사; Revised Romanization: Majimak Insa) while Stand Up spawned "Day by Day" (Korean: 하루하루; Revised Romanization: Haru Haru); both singles were chart-toppers.
Shortly after the debut of Big Bang, Daesung was diagnosed with voice chord nodules. For nearly a year, he struggled with his voice and developed sociophobia and stage fright. However, he was able to recover with the help of fellow singer and label-mate Gummy, who had been previously diagnosed with the illness, and the two became close because of this situation. Before the release of Big Bang's second album, Daesung's condition improved drastically.
