<P>PROBLEM TO BE SOLVED: To provide the operation method of a liquid crystal display device capable of making compatible characteristics of a PIN diode and characteristics of a data holding TFT. <P>SOLUTION: In the operation method of the liquid crystal display device 1, the intrinsic semiconductor layer of the PIN diode 4 is channel-doped with impurities having a prescribed concentration so that the intrinsic semiconductor layer becomes intrinsic during the application of a HIGH voltage to a light shielding film 10, and a voltage switching step is included where a voltage is switched so that a voltage with the same polarity as a voltage applied to a thin film transistor 6 is applied to the light shielding film 10 at the same timing as voltage application to the thin film transistor 6. <P>COPYRIGHT: (C)2011,JPO&INPIT |
