Abstract
Display apparatuses are enhanced in reliability in such a manner that external moisture is prevented from penetrating display regions and planarization layers are prevented from being stripped off. In particular, in a display apparatus including a display region containing organic light-emitting devices arranged on a circuit substrate, a bank-separating region separating a bank is provided in a planarization layer-separating region separating a planarization layer, an end portion of the planarization layer is covered with the bank, an end portion of an organic protective layer extending over the display region is spaced from a portion of the planarization layer that is located outside the bank-separating region and a portion of the bank that is located outside the bank-separating region, and the inorganic protective layer and an end portion of the bank that is disposed in the display region are covered with an inorganic protective layer.
