The horizontal and vertical conductive lines are disposed on the first substrate and overlapped each other to form a plurality of first protrusions. The second substrate is disposed over the first substrate. The main spacer and the compensation spacer are disposed on the second substrate. The main spacer is in sliding contact with the first protrusions, and the compensation spacer is disposed around the main spacer.
