Abstract
A display panel and a display device. A driving voltage line disposed in an active area is disposed to overlap a reference voltage line. The aperture ratio of a display panel is improved, and the transparency of a transparent display device is improved. The width of the driving voltage line disposed in the display panel gradually decreases in a direction away from a driver circuit supplying a driving voltage. Differences in the variation of the driving voltage according to the areas of the display panel are reduced, thereby improving brightness uniformity of the display panel according to the areas of the display panel.
