Abstract
A display panel includes a TFT substrate, an opposite substrate and a display layer. A TFT of the TFT substrate has a drain. A first insulating layer has a first sub-layer and a second sub-layer disposed on the drain sequentially. The first sub-layer has a first opening with a first width. The second sub-layer has a second opening with a second width on the first opening. The first and second openings form a first via, and the second width is greater than the first width. A passivation layer is disposed on the first insulating layer. A second insulating layer is disposed on the passivation layer. A pixel electrode layer is disposed on the second insulating layer and disposed in the first via to connect the drain. The display layer is disposed between the TFT substrate and the opposite substrate.
