Abstract

A display panel and a display device wherein the display panel includes multiple parallel scan lines and data lines crossing and insulated from each other. A nth scan line, a (n+1)th scan line, a mth data line, and a (m+1)th data line jointly define a first pixel area. The nth scan line, the (n+1)th scan line, a (m+2)th data line, and a (m+3)th data line jointly define a second pixel area. The nth scan line, the (n+1)th scan line, a (m+4)th data line, and a (m+5)th data line jointly define a third pixel area. Each of the first, second, and third pixel areas includes a number of sub-pixel units. The sub-pixel units in the first and third pixel areas are disposed in a structurally symmetric manner relative to the second pixel area. The present invention may reduce the complexity of designing the driving IC to the sub-pixel units.
