Abstract:
An active matrix substrate comprising:an insulating substrate; a plurality of scanning lines and signal lines provided on said insulating substrate in a matrix pattern; pixel electrodes, each of which being provided to areas enclosed by said scanning lines and signal lines, respectively; switching elements electrically connected to said scanning lines, signal lines, and pixel electrodes, respectively; and a resistance control element electrically connecting at least two lines selected arbitrarily from each of said scanning lines and signal lines, said resistance control element varying a resistance value between the at least two lines in response to a voltage applied to the resistance control element, the resistance control element having two thin film transistors (TFTs), and an ON resistance of the TFTs controls the resistance value between the at least two lines, wherein said each of said two thin film transistors each have a source electrode of a first TFT electrically connected to and a drain electrode of the other TFT.
