Matrix type liquid-crystal display unit |
摘要 |
A matrix type liquid-crystal display unit includes: a plurality of pixel portions which are arranged in the form of a matrix; a plurality of signal lines through which a display signal is supplied to the pixel portions; a plurality of scanning lines through which a scanning signal is supplied to the pixel portions; a signal-line drive circuit for driving the signal lines; a scanning-line drive circuit for driving the scanning-lines; a plurality of first thin-film transistors that form the signal-line drive circuit; a plurality of second thin-film transistors that form the scanning-line drive circuit; and a threshold value control circuit being connected to the signal-line drive circuit and the scanning-line drive circuit, for commonly controlling threshold values of the first and second thin-film transistors.
