A liquid crystal display, a display panel and a manufacturing method of a display device are disclosed. The liquid crystal display includes a backlight module and a display panel including a first region and a second region with different curvatures. The display panel receives a light from the backlight module, outputs a first light in the first region and outputs a second light in the second region. The first light and the second light respectively have a first normal brightness and a second normal brightness in a normal view angle, and respectively have a first oblique brightness and a second oblique brightness in an oblique view angle. A ratio of a difference between the first normal brightness and the second normal brightness to the first normal brightness is less than a ratio of a difference between the first oblique brightness and the second oblique brightness to the first oblique brightness.
