Abstract
A display apparatus includes, a first pattern included in a first layer, a second pattern included in a second layer, a first test pattern including a plurality of first lines extending in a first direction and having a first width, and being spaced apart from each other, a second test pattern included in the second layer, including a central line and a plurality of second lines connected to the central line, wherein the plurality of second lines extend in the first direction have a second width, and are spaced apart from each other, and wherein at least one of the second lines is electrically connected to the first lines, and a shift tester configured to apply a test voltage to the central line to determine a degree by which the second pattern is shifted with respect to the first pattern by measuring the voltages at the first lines.
