Abstract: A light emitting display apparatus includes a first substrate including pixels and signal lines arranged in a first direction and a second substrate disposed on a rear surface of the first substrate, wherein a routing portion including routing lines is provided in a first lateral surface of the first substrate and a second lateral surface of the second substrate. In the first substrate, a first pad portion adjacent to the first lateral surface includes first pads connected to the signal lines and the routing lines, a first secondary pad provided between the first pads, and a first connection line provided to overlap the first pads and the first secondary pad. In the second substrate, a second pad portion adjacent to the second lateral surface includes second pads connected to the routing lines, a second secondary pad provided between the second pads, and a second connection line provided to overlap the second pads and the second secondary pad. The routing portion includes a secondary routing line connecting the first secondary pad to the second secondary pad.
