Abstract: A display apparatus may include a first inorganic insulating layer disposed between a first semiconductor layer and a first gate electrode, a second inorganic insulating layer disposed between the first gate electrode and a capacitor electrode, a third inorganic insulating layer disposed on the capacitor electrode, a fourth inorganic insulating layer disposed between a second semiconductor layer and a second gate electrode, a fifth inorganic insulating layer disposed on the second gate electrode, a 1st-1 connection electrode disposed over the fifth inorganic insulating layer and electrically connected to the first semiconductor layer through a 1st-1 contact hole passing through the first to the fifth inorganic insulating layer, and a 1st-1 bridge contact layer covering a portion of the fifth inorganic insulating layer, an inner surface of the 1st-1 contact hole, and a portion of the first semiconductor layer corresponding to the 1st-1 contact hole.
