Abstract: A liquid crystal display (“LCD”) device is improved in terms of electrostatic discharge (“ESD”) tolerance, the LCD device including: a first substrate and a second substrate spaced apart from each other; a liquid crystal layer between the first substrate and the second substrate; a common line on the first substrate; a common electrode on the second substrate; and a plurality of short-circuit portions between the common line and the common electrode. Each of the plurality of short-circuit portions includes a contact surface contacting the common line, and at least two of the short-circuit portions respectively include contact surfaces having different sizes.

Abstract: An exposure mask includes an aligning portion and a boundary portion. The aligning portion may be aligned with pixel areas of a substrate and includes a first exposure member and a second exposure member. The boundary portion includes a first exposure element, a second exposure element, a third exposure element, and a fourth exposure element. The first exposure member, the first exposure element, and the second exposure element are positioned in a first row. The first exposure element is positioned between the first exposure member and the second exposure element and is larger than the second exposure element. The second exposure member, the third exposure element, and the fourth exposure element are positioned in a second row. The third exposure element is positioned between the second exposure member and the fourth exposure element and is smaller than the fourth exposure element. Each exposure member/element includes a light transmitter/blocker.

Abstract: A display device is capable of substantially preventing a short circuit between a common electrode and a test pad, the display device including: a first substrate and a second substrate; a thin film transistor disposed on the first substrate; a gate line and a data line connected to the thin film transistor; a test pad portion connected to the data line; a test line connecting the test pad portion and the data line; and a spacer disposed on the first substrate. The spacer includes: a first spacer disposed on the display area and supporting the first substrate and the second substrate; a second spacer disposed on the display area, the second spacer having a less height than a height of the first spacer; and a third spacer overlapping the test line and the test pad portion disposed on the non-display area, the third spacer not contacting the second substrate.
