Abstract
There are provided a liquid crystal driving circuit and a liquid crystal display device in which the display brightness and color variation to input display data values can be adjusted. Input display data of one line period are taken into a latch circuit (,) with a latch signal output from a latch address control circuit, and latch circuit (,) data are taken into a latch circuit (,) at the timing of a line clock. Further, the latch circuit (,) data are input to a decode circuit. In accordance with set data output from a set register which sets the set register setting data with a set register setting clock, a gray-scale voltage which is matched with data of each pixel is selected and output as a selection voltage from the decode circuit. The selection voltage is buffered in an amplifying circuit, and then a liquid crystal applying voltage is output.
