Abstract: The present application provides an image display method and an image display device. The image display method performs a gray-scale compensation on each data line, thereby preventing a problem of color crosstalk in a display panel. At the same time, an original image in the display panel is edge blurred, which can reduce an impact of the color crosstalk.
