• a first inorganic layer covering the light emitting element layer and disposed to correspond to the predetermined space;
• each of the plurality of barrier groups includes at least one first groove defined by the upper surface of the first inorganic layer overlapping the predetermined space, the at least one first groove has an upper portion having a smaller width than a width of a lower portion of the at least one first groove;
• and
• an organic layer is in direct contact with an upper surface of the first inorganic layer and fills the at least one first groove.
