摘要： The present invention provides a display device which is capable of fetching input signals of a small amplitude into the inside thereof. A level converting circuit includes a first-conductive-type first transistor having a gate electrode to which input signals are applied through a first capacitive element, a second-conductive-type second transistor having a gate electrode to which input signals are applied through a second capacitive element, a first bias circuit which applies a first bias voltage to the gate electrode of the first transistor and a second bias circuit which applies a second bias voltage to the gate electrode of the second transistor. Here, the first bias voltage is a voltage which turns off the first transistor when a voltage applied to the gate electrode of the first transistor assumes a maximum value and the second bias voltage is a voltage which turns off the second transistor when a voltage applied to the gate electrode of the second transistor assumes a minimum value.

摘要： A liquid crystal display device includes plural video signal input parts which supply pixel drive voltages to the respective video signal lines of a liquid crystal display device, and each of the video signal input parts includes a field-effect transistor, a first part which sets a voltage value of a control electrode of the field-effect transistor to a voltage value obtained by correcting a common pixel drive voltage by a threshold voltage of the field-effect transistor, a second part which sets the voltage value of the control electrode of the field-effect transistor to a voltage obtained by adding a video signal voltage to the voltage value corrected by the first part, and a third part which supplies a voltage obtained by adding the video signal voltage to the common pixel drive voltage, to the video signal line as well as to the field-effect transistor, the voltage value of whose control electrode is set by the second part to the voltage obtained by adding the video signal voltage to the voltage value corrected by the first part. This construction prevents the difference in offset level from occurring in the pixel drive voltage to be supplied to the respective video signal lines, owing to a shift of the threshold value of the field-effect transistor.
