A display unit comprising: a first substrate; a sealing substrate facing the first substrate;a plurality of light-emitting elements (10R, 10G, 10B) disposed, in a matrix, in the display region on the first substrate, and each including a stack structure having a first electrode layer, a luminous layer, and a second electrode layer, wherein each light-emitting element (10R, 10G, 10B) is an organic electroluminescence element; a first inorganic layer being a protective film provided in a level between the first substrate and the luminous layer, wherein the first inorganic layer covers a pixel driving circuit; a second inorganic layer that covers a plurality of the luminous layers, wherein the second inorganic layer is a moisture proof film; a first organic layer provided in a level between the first substrate and the first electrode layer; a second organic layer, being an aperture-defining layer, provided in a level between the first electrode layer and the second inorganic layer; a first separation groove that penetrates the first organic layer and the second organic layer, and surrounds the display region; a first sealing portion where the first inorganic layer and the second inorganic layer seal, at an inner side of the first separation groove, both the first organic layer and the second organic layer provided in the region surrounded by the first separation groove; and a second sealing portion where the first inorganic layer and the second inorganic layer seal, on a side opposite to the display region as viewed from the first sealing portion, both the first organic layer and the second organic layer provided in the region outside the first separation groove, wherein the second inorganic layer extends to the first inorganic layer via the first separation groove and fills the first separation groove, a third organic layer and the first organic layer are at opposite sides of the second inorganic layer, wherein the third organic layer is a filling layer including resin, an outer periphery of the third organic layer surrounds the display region, the third organic layer covers the plurality of light-emitting elements (10R, 10G, 10B) in the display region, wherein the third organic layer is provided on the second inorganic layer and bonded to the sealing substrate with a seal section interposed therebetween, the seal section being a member provided to seal each layer between the substrate and the sealing substrate from outside and being provided around the display region at and edge section of the sealing substrate, and the second sealing portion is not overlapped by the third organic layer. a first substrate;
