The invention discloses a display device and a method for displaying images by the display device. The display device comprises a display panel and a driving circuit, wherein the display panel comprises a first number of pixel columns, a second number of scanning lines and a first number of data lines; the driving circuit comprises a scanning driver and a data driver; each pixel column comprises a second number of pixel units, and the first number is an odd number; the scanning lines are connected with one pixel unit in the first number of pixel columns; the scanning driver is used for generating scanning driving signals and sending the scanning driving signals to the pixel units through the scanning lines; the data driver is used for generating data driving signals, sending the data driving signals to the pixel columns through the data lines and driving the display panel to display the images frame by frame in a preset cycle period through the data driving signals in a partial column reversing driving manner. Power consumption of the display device can be reduced.
