Abstract

A display apparatus includes a substrate, a first data line in a display area, a first input line in a peripheral area, and a first connecting wire electrically connected to the first input line in a peripheral area of the substrate. The first connecting wire transfers a first input signal from the first input line to the first data line. The first connecting wire includes a first connecting line disposed in a display area of the substrate and extending in the first direction, and a second connecting line electrically connected to the first connecting line and extending in a second direction intersecting the first direction. The first connecting line and the second connecting line are disposed on different layers.
