Patent ID: 7212183

Claim:
A liquid crystal display apparatus comprising: a plurality of pixels arranged in rows and columns, each for providing luminance corresponding to a display voltage; a plurality of first gate lines provided corresponding to respective said rows of said plurality of pixels; a plurality of second gate lines provided corresponding to respective said rows of said plurality of pixels; a plurality of data lines provided corresponding to respective said columns of said plurality of pixels; a gate drive circuit for driving each of said plurality of first and second gate lines to a voltage that is different between a select state in which corresponding one of said rows is selected for a scanning target in accordance with a prescribed scanning cycle and a non-select state except for said select state; and a source drive circuit for driving said plurality of data lines to said display voltage that corresponds to the pixels included in the row selected for said scanning target; said plurality of pixels each including a liquid crystal element having a pixel electrode and a common electrode for providing luminance that corresponds to a voltage difference between said pixel electrode and said common electrode, a first field-effect transistor electrically connected between corresponding one of said data lines and a first node, and having its gate electrically connected to corresponding one of said first gate lines, and a second field-effect transistor electrically connected between said first node and said pixel electrode, and having its gate electrically connected to corresponding one of said second gate lines; said gate drive circuit setting each voltage of said first and second gate lines in said select state to a first voltage that can turn-on each of said first and second field-effect transistors, while setting a voltage of said first gate line in said non-select state to a second voltage that can turn-off said first field-effect transistor as well as setting a voltage of said second gate line in said non-select state to a third voltage that is intermediate between a maximum value and a minimum value of said display voltage, wherein said third voltage is substantially at the same level throughout successive non-select states.
