Abstract
Provided is a display apparatus including: a substrate in which a display element is arranged; a first thin film transistor arranged in the display area and including a first semiconductor layer including silicon and a first control electrode insulated from the first semiconductor layer; a first interlayer insulating layer covering the first control electrode; a second thin film transistor arranged on the first interlayer insulating layer and including a second semiconductor layer including an oxide semiconductor and a second control electrode insulated from the second semiconductor layer; a second interlayer insulating layer covering the second control electrode; a node connection line arranged on the second interlayer insulating layer and connected to the first control electrode via a first contact hole; a first planarization layer covering the node connection line; and a shielding electrode arranged on the first planarization layer to overlap the node connection line.
