Abstract:
1. A display panel, having a display region and a sealant region, comprising: a first substrate; a pixel array, located within the display region on the first substrate; a driving circuit, located within the sealant region of the first substrate, wherein the driving circuit comprises a plurality of switch devices and a plurality of turn-line structures; a common electrode, located within the sealant region of the first substrate; a planar layer, located on the first substrate and covering the pixel array, the driving circuit and the common electrode, wherein the thickness of the planar layer at the turn-line structure of the driving circuit is less than the thicknesses of other portions and there is a contact hole in the planar layer to expose the common electrode; a conductive layer, located on the planar layer and electrically connected to the common electrode via the contact hole; a second substrate, located oppositely to the first substrate; an electrode layer, located on the second substrate; a liquid crystal layer, located within the display region between the first substrate and the second substrate; a sealant, located within the sealant region between the first substrate and the second substrate; and a plurality of conductive balls, distributed in the sealant, wherein the conductive layer on the first substrate is electrically connected to the electrode layer on the second substrate though the conductive balls.
