There are many complaints about the Premium Wallpapers HD app, which apparently started to show ads looking like this after its latest update. In general, an Android app can draw anything over other apps if it has the “Draw over other apps” permission, so you can check which of your installed apps have this permission.
Those ads are shown because of some installed apps in your phone, like Applock. These apps are always run in background and, after some interval of time, the ad is shown again. First find the app(s) which show those ads. Then uninstall those app(s).
You've got some kind of adware. Check your running apps and stop any apps that are unfamiliar-looking. Be sure to checked cached processes as well.
