A display panel comprises a first substrate, a second substrate and a liquid crystal layer. The first substrate includes a first transparent conductive layer and a first alignment layer. The first transparent conductive layer includes a first surface and has at least a first notch, the first alignment layer includes a first part and a second part, the first part is disposed in the first notch, the second part is disposed on the first surface, and the surface roughness of the first part of the first alignment layer is greater than that of the second part. The second substrate is disposed opposite to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate. A display device having the display panel is also disclosed.
