Abstract

A display device may include: a base layer including a display area and a non-display area; and a plurality of pixels provided on the display area, and each including a plurality of sub-pixels. Each of the sub-pixels may include a pixel circuit layer, and a display element layer including an emission area formed to emit light, and a non-emission area provided around a perimeter of the emission area. The display element layer may include: a partition wall provided on the emission area of each of the sub-pixels; a bank provided on the non-emission area of each sub-pixel, and disposed on a surface equal to a surface on which the partition wall is disposed; a first electrode and a second electrode provided on the partition wall and spaced apart from each other; and at least one light emitting element provided between the first and second electrodes in the emission area of each sub-pixel, and configured to emit the light.
