A method for detecting a storage voltage, a display apparatus using the storage voltage and a method for driving the display apparatus. The method for detecting the storage voltage includes applying a test voltage to a storage line in a display panel having an active layer disposed between the storage line and a data line while varying the test voltage, the active layer being in an active state or an inactive state according to the test voltage, and detecting the storage voltage corresponding to the test voltage in an inactive state of the active layer. Thus, the display panel is driven by using the detected storage voltage, so that an aperture ratio may be increased and current consumption may be decreased.

A liquid crystal display panel includes a first substrate, a second substrate facing the first substrate, and a liquid crystal layer interposed therebetween. The second substrate includes gate lines, data lines crossing the gate lines to define sub-pixel regions, a thin film transistor connected to a gate line and a data line, an organic passivation layer, a pixel electrode connected to the thin film transistor, a repair portion where the pixel electrode overlaps with a previous gate line, and a repair hole formed in the repair portion to penetrate the organic passivation layer. The pixel electrode is arranged in the repair hole. A method for repairing a defective pixel includes connecting a gate extending portion of the previous gate line to the pixel electrode in the repair portion using a laser, and cutting the defective pixel's drain electrode connected to the pixel electrode.

A display apparatus includes a substrate, gate lines disposed on the substrate, data lines extending across the gate lines, and pixels connected to the gate lines and the data lines. The pixels arranged in a matrix of rows and columns. The pixels disposed in the same columns are alternately connected to data lines disposed to the left or right sides of the column. The pixels may be disposed in different display areas of the substrate. Adjacent pixels in the same columns but in different display areas may be connected to the same data line.

A gate driver for a liquid crystal display includes a shift register including a plurality of stages for outputting gate drive signals. Each of the stages includes a pull-up circuit for providing the gate drive signal to an output terminal in response to first and second clock signals, a pull-down circuit for providing a gate off signal to the output terminal, a pull-up driving circuit for driving the pull-up circuit in response to a first control signal, and a pull-down driving circuit for driving the pull-down circuit in response to a second control signal. Each of the stages includes a plurality of switching devices. A node of nodes where a signal line, through which the first clock signal, the second clock signal, the first control signal or the second control signal is applied, is electrically connected to a switching device includes at least two contacts.

A display apparatus includes a first sub-pixel and a second sub-pixel. The first sub-pixel and the second sub-pixel are electrically and respectively connected to a first gate line and a second gate line adjacent to each other and are electrically connected to a data line. The display apparatus further includes a connection line disposed between sub-pixel electrodes of the first and second sub-pixels. The connection line has two ends connected to the data line and serves as an additional or alternative path for transmitting a data signal that is transmitted by the data line.
