Abstract
Display devices and, in particular, electroluminescent display devices including a lower structure of a bank causing a highly conductive hole injection layer to take on a shape so as to reduce a leakage current, and a method for manufacturing the same are described. An electroluminescent display device includes a substrate having a plurality of pixels, a bank located at a boundary between the subpixels, a first electrode in each subpixel, a separation induction layer between the bank and the first electrode, a p-type layer with a first portion on the bank and a second portion on an emission assembly of the subpixels, and at least one common layer on the p-type layer.
