A display apparatus comprising: a display panel having sides extending along a first direction and along a second direction perpendicular to the first direction and including a display area configured to display an image and a non-display area adjacent to the display area on one side thereof in the first direction; a timing controller configured to receive a control signal and an input image signal (DATA_IN), and to output a first control signal, a second control signal, and a data signal (DATA_SG); a gate driver arranged in the non-display area and configured to generate a gate signal in response to the first control signal, and to apply the gate signal to gate lines from the non-display area; and a data driver arranged in the non-display area and configured to convert the data signal (DATA_SG) to a data voltage (DATA) in response to the second control signal, and to apply the data voltage (DATA) to data lines from the non-display area, wherein the display area comprises: the gate lines; the data lines crossing the gate lines and insulated from the gate lines; gate dummy lines extending substantially in parallel to the gate lines, spaced from the gate lines, and formed at the same layer as the gate lines; data contact parts coupling the gate dummy lines to the data lines at one end side of the display panel in the second direction; and pixels coupled to the gate lines and the data lines. a display panel having sides extending along a first direction and along a second direction perpendicular to the first direction and including a display area configured to display an image and a non-display area adjacent to the display area on one side thereof in the first direction; a timing controller configured to receive a control signal and an input image signal (DATA_IN), and to output a first control signal, a second control signal, and a data signal (DATA_SG); a gate driver arranged in the non-display area and configured to generate a gate signal in response to the first control signal, and to apply the gate signal to gate lines from the non-display area; and a data driver arranged in the non-display area and configured to convert the data signal (DATA_SG) to a data voltage (DATA) in response to the second control signal, and to apply the data voltage (DATA) to data lines from the non-display area, wherein the display area comprises: the gate lines; the data lines crossing the gate lines and insulated from the gate lines; gate dummy lines extending substantially in parallel to the gate lines, spaced from the gate lines, and formed at the same layer as the gate lines; data contact parts coupling the gate dummy lines to the data lines at one end side of the display panel in the second direction; and pixels coupled to the gate lines and the data lines. the gate lines; the data lines crossing the gate lines and insulated from the gate lines; gate dummy lines extending substantially in parallel to the gate lines, spaced from the gate lines, and formed at the same layer as the gate lines; data contact parts coupling the gate dummy lines to the data lines at one end side of the display panel in the second direction; and pixels coupled to the gate lines and the data lines.
