Liquid crystal display device, voltage setting method for liquid crystal display device and method for producing liquid crystal display device
Abstract:
A liquid crystal display device includes a liquid crystal display panel including a plurality of pixels, and a control circuit configured to generate a source signal voltage supplied to each pixel. The liquid crystal display panel includes an active matrix substrate including a pixel electrode applied with a source signal voltage and a common electrode applied with a common voltage. The common voltage and the source signal voltage corresponding to each gradation are set such that a source-common center difference at least one of lowest and highest gradation levels is greater than the source-common center difference at least some of the other gradation levels. A degree of symmetry of a gradation level voltage is equal to or lower than 95% at least at one of gradation levels equal to or lower than a 127/255-th gradation level except for the lowest gradation level.
