To provide a driving method for a display device, by which the decrease in visibility of a display device is suppressed.SOLUTION: In a driving method for a display device, pixel data including a first data value expressing the grayscale of a first color, a second data value expressing the grayscale of a second color different from the first color, and a third data value expressing the grayscale of a third color different from the first color and the second color is corrected. In the driving method for a display device, the maximum value, the minimum value, and the intermediate value of the first data value, the second data value, and the third value are determined by comparing the first data value, the second data value, and the third value, and first determination is performed using, as correction candidate data, the pixel data in which all the first data value, the second data value, and the third value are the same, the pixel data in which the ratio of the maximum value to the intermediate value is 1 or more and 1.5 or less, and the pixel data in which the ratio of the intermediate value to the minimum value is 1 or more and 1.5 or less.SELECTED DRAWING: Figure 8 【課題】表示装置の視認性の低下を抑制する表示装置の駆動方法を提供すること。【解決手段】第１の色の階調を表す第１のデータ値と、第１の色と異なる第２の色の階調を表す第２のデータ値と、第１の色および第２の色と異なる第３の色の階調を表す第３のデータ値とを含む画素データを補正する表示装置の駆動方法であって、表示装置の駆動方法は、第１のデータ値、第２のデータ値、および第３のデータ値の比較によって、前記第１のデータ値、前記第２のデータ値、および前記第３のデータ値のうちの最大値、最小値、および中間値を決定し、第１のデータ値、第２のデータ値、第３のデータ値の全てが一致する画素データ、中間値に対する最大値の比が１以上１．５以下である画素データ、または最小値に対する中間値の比が１以上１．５以下である画素データを、補正候補データとする第１の判定を行うことを含む。【選択図】図８
