The invention provides a display panel, a display device and a lens coordinate determining method. According to the display panel, a substrate is divided into M*N display areas. Furthermore each display area is provided with at least two image blocks and at least two lenses. Each lens is in one-to-one correspondence with the image block. Furthermore the lens is arranged at the light outlet side of the image block. What needs to be explained is that the arrangement manners of the lenses in at least two display areas are different in all display areas which are included in the display panel, wherein the coordinates of the lenses in the display areas with the same lens arrangement manner are calculated according to the same algorithm. According to the display panel, the display device and the lens coordinate determining method provided by the invention, the display panel is divided into partially same display areas and partially different display areas or totally different display areas according to the lens arrangement mode, and individual calculation for the coordinate of the lens in each display area is required, thereby reducing complexity in performing error checking on the display panel.
