Abstract

To provide a display device that can improve yield. [Solution] The display device comprises a substrate having a display area and a peripheral area, an organic insulating layer disposed above the substrate, a rib layer disposed above the organic insulating layer, a partition wall disposed above the rib layer, a laminated film disposed in the display area and the peripheral area, a sealing layer made of an inorganic insulating material that covers the laminated film, and a first resin layer that covers the sealing layer. The partition wall comprises a first partition wall that surrounds each of a plurality of subpixels, and a second partition wall disposed above the organic insulating layer in the peripheral area. The sealing layer comprises a first sealing layer disposed in the display area and a second sealing layer disposed in the peripheral area. The first end of the second sealing layer in the peripheral area is located between the second end of the organic insulating layer and the third end of the second partition wall in a plan view. The first end is thinner than the thickness of the second sealing layer located above the second partition wall, and has a width equal to or greater than its thickness.
