Abstract: Disclosed are a display device and a display panel including a substrate, a first subpixel array including first subpixels arranged in a first region on the substrate, a second subpixel array including second subpixels arranged in a second region on the substrate, and a third subpixel array including third subpixels arranged in a third region on the substrate. The first region, the second region, and the third region are spatially separated and provided side by side on a same surface of the substrate. The first subpixels are grouped by a first primary color and are patterned as the first subpixel array in the first region. The second subpixels are grouped by a second primary color and are patterned as the second subpixel array in the second region. The third subpixels are grouped by a third primary color and patterned as the third subpixel array in the third region.
