摘要： A display device of at least one embodiment of the present invention has a connection changeover circuit, including switch elements for time-division driving, formed on a liquid crystal panel, and the switch elements are paired so that two switch elements in each pair are connected in parallel to one video signal line. The paired switch elements are turned on at the same time, and immediately before one of the switch elements is turned off upon completion of a charging period for its corresponding video signal line, only the other switch element is turned off. As a result, while maintaining drive performance, it is possible to solve the impact of fieldthrough phenomenon caused by one of the switch elements, which are transistors, and also reduce parasitic capacitance formed in the other switch element, thereby suppress the impact of fieldthrough phenomenon caused by that switch element.

摘要： A peripheral region of a display panel includes a signal distribution device (4) for time-dividing and distributing, to output terminals (7), an output signal from a source driver. The signal distribution device (4) includes switching elements (20) for the output terminals (7). Each switching element (20) is controlled by a selection signal supplied to a control line (9) connected with a gate electrode. Each switching element (20) includes a source electrode and the drain electrode each having a comb-like shape having a stem part and branch parts extending therefrom. In at least one switching element (20), only all of or part of the branch parts overlap the control line (9) and a semiconductor layer (10). This suppresses abnormal heat generation of a source driver in a display device including the signal distribution circuit by which an output signal from the source driver is distributed to pixels in time series.

摘要： A shift register according to the present invention is supported on an insulating substrate and has multiple stages that sequentially shift an output signal from one stage to the next. Each of those stages has a circuit 20 including multiple thin-film transistors. The multiple thin-film transistors include a first thin-film transistor MK, which influences the operation of the circuit, and a second thin-film transistor MK_YOBI, which has at least one floating terminal and other terminal(s) that is/are connected to corresponding terminal(s) of the first thin-film transistor MK. The at least one floating terminal is arranged so as to be connectible to a predetermined line N2. Consequently, the yield of shift registers with a monolithic gate driver can be increased.
