Abstract
Provided area a TFT substrate, a liquid crystal display panel, a display module and an electronic device. In the TFT substrate provided by the embodiment of the present application, by arranging the preset electrode and the common electrode to be connected to the same line connector, if there is a short circuit between the preset electrode and the common electrode, it can be avoided that the voltage signal on the preset electrode being pulled down to lead the abnormal display conditions, such as vertical gradient lines on the display screen.
