Abstract: The disclosure has an object to achieve a high level of height precision for spacers on a back plane. A display device includes: edge covers having a plurality of openings in which first electrodes are exposed; and a planarization film having first flat portions, second flat portions, and contact holes. The plurality of openings respectively overlap the first flat portions in a plan view. The second flat portions are located between the plurality of openings in a plan view. Each edge cover overlapping one of the first flat portions in a plan view has, on a second electrode side, a surface that has a first height from a bottom surface of the planarization film on a substrate side. Each second flat portion has, on the second electrode side, a surface that has a second height from the bottom surface. The first height is smaller than the second height.
