Abstract
A large-sized organic EL display unit is formed by bonding four small display panels on junction surfaces so that the pitch between emission parts adjacent to each other over the small display panels is equal to the pitch between the emission parts in the small display panels, so that the junction between the adjacent ones of the small electroluminescence display panels is inconspicuous.
