Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid crystal display device which restrains a drop in image quality compared with the case where corrections are made on the basis of the difference in gradations. SOLUTION: The liquid crystal display device includes: data lines; a plurality of pixel circuits; a data line-driving circuit which applies data line potential to the data line; and a control circuit which finds the data line potential, obtained by correcting gradation potential which makes each pixel circuit display display gradation on the basis of information which indicates the display gradation of each pixel circuit. The control circuit finds the data line potential so that a correction amount from a first potential to the data line potential, when the gradation potential of a frame to be displayed is the first potential and the gradation potential of the immediately preceding frame is a second potential which is different from the first potential, is different from the correction amount from the first potential to the data line potential, when the gradation potential of the frame to be displayed is the second potential and the gradation potential of the immediately preceding frame is the first potential.
