An image display device according to a first present disclosure has a display region configured by arranging a plurality of pixels in a matrix form. The image display device includes: a display region configured by arranging a plurality of pixels in a matrix form; a plurality of gate signal lines respectively disposed for each pixel row including a first pixel row and a second pixel row different from each other in the display, and the plurality of gate signal lines being used to select a pixel row in which a data voltage corresponding to image data is written; a gate driver that supplies a gate signal to the plurality of gate signal lines; a plurality of data signal lines respectively disposed for each pixel column in the display, the plurality of data signal lines being used to write the data voltage in pixels of the selected pixel row; and a source driver that supplies the data voltage to the plurality of data signal lines; and a controller that determines whether the second pixel row has correlation with the first pixel row in an image, and controls the gate driver and the source driver based on a determined result. When determining that the second pixel row has the correlation with the first pixel row, the controller causes the source driver to supply the data voltage corresponding to the first pixel row, causes the gate driver to supply the gate signal to write the data voltage in the first pixel row, and causes the gate driver to supply the gate signal to write the data voltage corresponding to the first pixel row in the second pixel row.
