Display panels

Abstract

A display panel includes a substrate. A scan line and a data line intersect with each other and are disposed on the substrate. An active layer is disposed on the substrate and between the data line and the substrate. A transparent conductive layer is disposed on the substrate and above the active layer. The active layer includes a contact region electrically connected to the data line, a second contact region electrically connected to the transparent conductive layer, and an intermediate region disposed between the first and the second contact regions. A portion of the intermediate region overlapping with the scan line is a channel region. A portion of the intermediate region not overlapping with the scan line is a non-channel region. The width of the non-channel region is greater than the width of the channel region.

What is claimed is: 
     
         1 . A display panel, comprising:
 a first substrate;   a scan line and a data line intersecting with each other to form an intersecting region and disposed on the first substrate, wherein the scan line extends along a first direction; and   an active layer disposed on the first substrate and between the data line and the first substrate;   wherein the active layer comprises:   a first contact region electrically connected to the data line through a first via hole;   a first channel region overlapping a portion of the scan line;   a second channel region overlapping another portion of the scan line; and   a non-channel region not overlapping the scan line and connected between the first channel region and the second channel region,   wherein at least a portion of an outline of the non-channel region has an arc shape.   
     
     
         2 . The display panel of  claim 1 , wherein a width of the first via hole along the first direction is greater than a width of the data line in the intersecting region along the first direction. 
     
     
         3 . The display panel of  claim 1 , wherein at least a portion of an outline of the data line has an arc shape. 
     
     
         4 . The display panel of  claim 1 , wherein an outline of the data line corresponding to the first via hole has an arc shape. 
     
     
         5 . The display panel of  claim 1 , further comprising a first conductive layer,
 wherein the active layer further comprises a second contact region electrically connected to the first conductive layer.   
     
     
         6 . The display panel of  claim 5 , wherein the first conductive layer is an electrode. 
     
     
         7 . The display panel of  claim 5 , wherein the first conductive layer is a patterned electrode. 
     
     
         8 . The display panel of  claim 5 , further comprising:
 a drain electrode electrically connected to the active layer through a second via hole.   
     
     
         9 . The display panel of  claim 8 , wherein the first conductive layer is electrically connected to the active layer through a third via hole. 
     
     
         10 . The display panel of  claim 9 , wherein the first conductive layer is electrically connected to the drain electrode through the third via hole. 
     
     
         11 . The display panel of  claim 9 , wherein a projection of the second via hole on the first substrate at least partially overlaps a projection of the third via hole on the first substrate. 
     
     
         12 . The display panel of  claim 9 , wherein a projection of the second via hole on the first substrate and a projection of the third via hole on the first substrate are not overlapping. 
     
     
         13 . The display panel of  claim 5 , further comprising a second conductive layer disposed on the first substrate. 
     
     
         14 . The display panel of  claim 13 , wherein the first conductive layer is insulated from the second conductive layer. 
     
     
         15 . The display panel of  claim 1 , further comprising:
 a second substrate disposed opposite to the first substrate; and   a display medium disposed between the first substrate and the second substrate.
