摘要: According to one embodiment, a display device comprises a first lower electrode, a rib including a first pixel aperture, a partition including a lower portion on the rib and an upper portion protruding from a side surface of the lower portion, a first upper electrode, and a first organic layer between the first lower electrode and the first upper electrode. The lower portion includes a bottom layer and a stem layer on the bottom layer. The bottom layer is formed of a material which has a smaller etching rate to a mixed acid containing phosphoric acid, nitric acid, and acetic acid than the stem layer and which is conductive.
