Abstract:
Provided are a liquid crystal display apparatus and a method for driving a liquid crystal display apparatus capable of effectively suppressing the deterioration in gamma characteristics even when an angle between a normal line to a display screen from a position of observation and an observer's line of sight is relatively large. Pixels P, arranged in a matrix, are defined to include a plurality of pairs of electrodes for applying a voltage to a liquid crystal layer. Each of two subpixels included in each pixel P is defined to include a pair of electrodes consisting of a subpixel electrode and a counter electrode. A pair of electrodes in each of the two subpixels included in the pixel P (including a pair of electrodes in a third subpixel which may also be included in the pixel P) applies a voltage to the crystal liquid layer. A voltage difference between any two voltages applied to the crystal liquid layer is set to vary in accordance with the arrangement position of the pixel P along the rows and/or columns of the matrix.
