Abstract

The invention relates to a thin film transistor substrate and a manufacturing process thereof. The thin film transistor substrate comprises a plurality of first scanning beams, second scanning beams, data wires, first pixel electrodes, second pixel electrodes, first thin film transistors and second thin film transistors. The first scanning beams are parallel with each other, the second scanning beams are parallel with the first scanning beams as well as insulated and overlapped with the first scanning beams; and the data wires are vertically insulated and crossed with the first scanning beams and the second scanning beams. Grids of the first thin film transistors are connected to the first scanning beams, source electrodes are connected to the data wires, and drain electrodes are connected to the first pixel electrodes; and grids of the second thin film transistors are connected to the second scanning beams, source electrodes are connected to the data wires, and drain electrodes are connected to the second pixel electrodes. The thin film transistor substrate has a high aperture opening ratio.

Description

technical field [0001] The invention relates to a thin film transistor substrate and a manufacturing process thereof. Background technique [0002] A liquid crystal display panel usually includes a thin film transistor substrate, a color filter substrate and a liquid crystal layer sandwiched between the two substrates, which realizes light by controlling the twisting of the liquid crystal molecules between the two substrates by applying voltages respectively. Pass or fail, so as to achieve the purpose of display. The liquid crystal driving method of the traditional liquid crystal display panel is the twisted nematic mode, but its viewing angle range is relatively narrow, that is, when the picture is observed from different angles, different display effects will be observed. [0003] In order to solve the problem of the narrow viewing angle of the twisted nematic mode liquid crystal display panel, the industry proposes a four-domain vertical alignment type liquid crystal dis...
