A display apparatus includes a gate line, a data line crossing the gate line and a pixel area. A common electrode and a pixel electrode are overlapped with each other and formed in the pixel area. The common electrode and the pixel electrode receive different voltages. The data line includes a first data line through which a voltage is applied to the common electrode and a second data line through which a voltage is applied to the pixel electrode. The first data line crosses the pixel area to minimize an area where the first data line is formed, thereby improving an aperture ratio of the display apparatus.

Display apparatus with data line and common line formed in a same layer

A TFT array panel and a manufacturing method thereof. The TFT array panel includes an insulation substrate, a plurality of gate lines, a plurality of first dummy wiring lines, a gate insulating layer, and a plurality of data lines. The insulation substrate has a display area for displaying an image and a peripheral area outside the display area. The plurality of gate lines are formed in the display area and in a portion of the peripheral area. The plurality of first dummy wiring lines are insulated from the gate lines and formed in the peripheral area. The gate insulating later is formed on the gate lines and the first dummy wiring lines, and has at least one contact hole exposing at least lateral end portions of the first dummy wiring lines. The plurality of gate lines are formed on the gate insulating layer, define a plurality of pixel areas that form the display area by being insulated from the plurality of gate lines and crossing the plurality of gate lines, and are connected with the at least lateral end portions of the first dummy wiring lines through the at least one contact hole. With this configuration, data voltages can be efficiently applied to respective pixel electrodes of the display area even though the data line, particularly the data fan-out unit, in the peripheral area is disconnected.
