Abstract
According to one embodiment, a method of manufacturing a display device, a substrate including a pair of partitions and a lower electrode disposed between the pair of partitions is formed. Then, an organic EL layer including a first portion including a pair of end surfaces which cover the lower electrode and are in contact with side surfaces of the pair of partitions, and a second portion located on each of the pair of partitions and spaced apart from the first portion, is formed. Thereafter, the second portion is removed by etching. Further, an upper electrode which covers the first portion is formed.
