Abstract
A display device includes: first electrodes formed to be arranged in a two-dimensional matrix on a substrate; a partition wall part provided between the first electrodes adjacent to each other and having a cross-sectional shape whose width decreases as it moves away from the substrate; an organic layer formed on an entire surface including surfaces of the first electrodes and the partition wall parts and formed by laminating a plurality of material layers; and a second electrode formed on an entire surface including a surface of the organic layer, in which among the plurality of material layers constituting the organic layer, a material layer arranged closest to the second electrode side is formed such that a resistance of a portion located on a slope of the partition wall part is higher than a resistance of a portion located on the first electrode.
