Claim 12:
13. A display panel, comprising:
a driving circuit layer, comprises a binding layer, a display base, and an array circuit layer which are stacked; wherein the driving circuit layer comprises:
an insulating layer, wherein the insulating layer is non-free-standing and deposited by a thick film process or by a coating process, the insulating layer is oxide insulating layer or nitride insulating layer, the thickness of the insulating layer is less than the thickness of a hard substrate or the thickness of a flexible layer, and the overall thickness of the display panel is reduced;
a first through hole, disposed in the insulating layer;
a first metal layer, disposed on the surface of the insulating layer; wherein the first metal layer is partially arranged in the first through hole and electrically connected to the binding layer; the first metal layer is patterned to a connecting portion electrically connected to the binding layer;
a semiconductor layer, disposed on the side of the insulating layer away from the binding layer; the semiconductor layer forms a channel, a source, and a drain;
a plurality of light emitting units, disposed on one side of the array circuit layer; wherein the light emitting units are electrically connected to the array circuit layer;
a cover substrate, disposed on one side of the plurality of light emitting units; wherein, the cover substrate is free-standing;
the plurality of the light emitting units, the driving circuit layer, the insulating layer and the binding layer are subsequently arranged on the cover substrate, wherein the plurality of the light emitting units, the driving circuit layer, the insulating layer and the binding layer are supported by the cover substrate.
