A display method of an image display device according to a third present disclosure is provided. The image display device includes a display region configured by arranging a plurality of pixels in a matrix form. The display method includes: determining whether a second pixel row has correlation with a first pixel row in an image in the first pixel row and the second pixel row that are different from each other in the display; and causing a source driver to supply a data voltage corresponding to the first pixel row, causing gate driver to supply a gate signal to write the data voltage in the first pixel row, and causing the gate driver to supply the gate signal to write the data voltage corresponding to the first pixel row in the second pixel row when determining that the second pixel row has the correlation with the first pixel row.
A display method of an image display device according to a fourth present disclosure is provided. The image display device includes a display region configured by arranging a plurality of pixels in a matrix form. The display method includes: inverting a phase of polarity of a data voltage in units of m (m is an integer of 1 or more) pixel rows; and shifting a position of a pixel row where the phase of the polarity of the data voltage is inverted by every predetermined pixel rows in each frame.
