Abstract: A plurality of pixel electrodes are provided in a display region. A plurality of pixel transistors corresponding to the plurality of pixel electrodes in a one-to-one manner are provided in a region outside the display region. Each of the pixel transistors is connected to the corresponding pixel electrode by a pixel wiring line. An input pad group, to which a drive signal group for driving the plurality of pixel transistors is input, is provided on a TFT substrate. Here, of a region on the TFT substrate, the plurality of pixel transistors are provided only in a region other than a region between the input pad group and the display region.

Abstract: A signal obtained through sampling a gate start pulse signal GSP by using one of a plurality of gate clock signals is supplied as a shift pulse for a forward shift action (a forward shift start pulse signal) to the first stage of a plurality of stages constituting a bidirectional shift register, and a signal obtained through sampling the gate start pulse signal GSP by using another one of the plurality of gate clock signals is supplied as a shift pulse for a backward shift action (a backward shift start pulse signal) to the last stage of the plurality of stages constituting the bidirectional shift register.
