A display apparatus includes a substrate including a display area including a display element, a first thin film transistor disposed in the display area, the first thin film transistor including a first semiconductor layer including a silicon semiconductor and a first gate electrode insulated from the first semiconductor layer, a second thin film transistor disposed in the display area, the second thin film transistor including a second semiconductor layer including an oxide semiconductor and a second gate electrode insulated from the second semiconductor layer, a first signal line extending at a side of the first thin film transistor in a first direction, a second signal line extending at an opposite side of the first thin film transistor in the first direction, and a shielding pattern extending in the first direction, the shielding pattern at least partially overlapping the first signal line.
