Abstract: A display panel and an electronic device including the display panel are provided. The display panel includes a binding region and a signal bus line region. The signal bus line region includes a first region defined aligned to the binding region and a second region located on two opposite sides of the first region. By reducing a distance between sides away from each other of a first and a last of the signal bus lines in the first region, a distance between the binding region and the display region is reduced, thereby reducing a width of a lower bezel of the display panel.

Abstract: Embodiments of the present application disclose a display panel and a preparation method thereof, and a display device. The display panel comprises a polymer liquid crystal cell and a light source. The polymer liquid crystal cell comprises a first region close to the light source and a second region away from the light source, and the second region has a higher haze than the first region, thereby reducing the light emitting intensity close to the light source region and increasing the light emitting intensity away from the light source region, so that light guide and light emitting in each region of the polymer liquid crystal cell uniform.

Abstract: A display panel, a manufacturing method thereof, and a display device are disclosed. For the display panel, an anti-crack structure is disposed in a chamfer between a driving circuit layer and a substrate. The anti-crack structure is in contact with a packaging layer to reduce an angle from the contact plane of the anti-crack structure and the packaging layer to the plane in which a light-emitting layer is located, so that the packaging layer is smoothly disposed, the risk of the fracture of the packaging layer is lowered, and the failure of the display panel is avoided.
