Abstract
A display device includes: a first substrate including a display area and a non-display area; a gate line in the display area and a gate pad in the non-display area, the gate line extending in a first direction; a data line in the display area, the data line extending in a second direction intersecting the first direction; a thin film transistor at an intersection point among the gate line and the data line; a step-difference pattern on the gate pad; and a protective layer including a first protective layer on the thin film transistor and a second protective layer on the step-difference pattern and the gate pad. The second protective layer has a height less than a height of the first protective layer.
