Patent ID: 8144096

Claim:
A liquid crystal display device comprising: a first substrate; a second substrate; a liquid crystal composition which is held between the first substrate and the second substrate; a plurality of pixel electrodes which are provided on the first substrate; a counter electrode which is placed to face corresponding one of the plurality of pixel electrodes; a switching element which supplies a data signal to corresponding one of the plurality of pixel electrodes; a data signal line which supplies the data signal to the switching element; a scanning signal line which supplies a scanning signal for controlling the switching element; a counter electrode signal line which supplies a voltage to the counter electrode; and a drive circuit which outputs the data signal and the scanning signal, wherein the drive circuit includes a gray scale voltage generating circuit having a variable resistor circuit and an amplitude correction register, wherein the amplitude correction register holds a plurality data items for correcting a gray scale voltage according to a position of the scanning signal line, and wherein the variable resistor circuit has a resistance value which is varied depending on the position of the scanning signal line and the data items held by the amplitude correction register.
