Patent ID: 8619014

Claim:
A liquid crystal display device comprising: a liquid crystal display panel; a plurality of pixel electrodes which are mounted on the liquid crystal display panel; a common electrode which is arranged on the same substrate as the pixel electrodes and forms an electric field between the common electrode and the pixel electrodes; pixel transistors each of which is connected to the pixel electrode and constitutes a switch for applying a grayscale voltage to the pixel electrode; data signal lines which are connected to the pixel transistors and to which the grayscale voltage is applied; equalizing transistors which constitute switches for making the common electrode and the data signal lines conductive with each other; and a shift register which sequentially applies a signal to gate lines of the pixel transistors, wherein the equalizing transistor is located at a position sandwiched between the same substrate and the common electrode, and is operated so as to make the common electrode and the data signal line conductive with each other at a cycle that the polarity of the common electrode is reversed, and the shift register includes a transistor which constitutes a damper for attenuating a potential difference.
