Abstract: A display apparatus with a moisture barrier structure and a method for manufacturing the display apparatus are disclosed. The display apparatus includes a first thin film transistor on a substrate, a separation layer disposed on the first thin film transistor and including an organic material, an inorganic insulating layer on the separation layer, a buffer layer on the inorganic insulating layer, a second thin film transistor on the buffer layer, and a display element connected to any one of the first thin film transistor and the second thin film transistor, wherein the separation layer has a recess, the recess has an opening in a direction toward the inorganic insulating layer, and the inorganic insulating layer is not disposed in the opening.
