Display substrate having arched signal transmission line and manufacture method thereof

Abstract

This invention discloses a display device mother substrate, a display device substrate and a manufacture method of display device substrate thereof. The display device mother substrate includes a first substrate, a second substrate, a first active area circuit and a first transmission line, wherein a first cutting line is defined between the first substrate and the second substrate. The first active area circuit is disposed on the first substrate and is electrically connected to the first transmission line. The first transmission line includes a display line portion, an end line portion and a middle line portion, wherein the display line portion is electrically connected to the first active area circuit. The middle line portion is disposed on the second substrate, wherein two ends of the middle line portion are electrically connected to the display line portion and the end line portion respectively at the first cutting line. The display device mother substrate is cut along the first cutting line to be separated into the first substrate and the second substrate, wherein the middle line portion is also separated from the display line portion and the end line portion.

What is claimed is: 
     
         1 . A manufacture method of a display device substrate, comprising:
 providing a display device mother substrate including at least one first substrate and a second substrate, the first substrate having an active area within an active area circuit thereon;   disposing a first transmission line circuitously on the display device mother substrate, wherein a display line portion and an end line portion of the first transmission line are located on the first substrate, and a middle line portion of the first transmission line connected to the display line portion and the end line portion are located on the second substrate, wherein the display line portion is electrically connected to the active area circuit;   separating the display device mother substrate into the first substrate and the second substrate to separate the middle line portion, the display line portion, and the end line portion; and   disposing a second transmission line on both the first substrate and the second substrate before the cutting step, wherein the second transmission line and the end line portion of the first transmission line cross over each other on the first substrate.   
     
     
         2 . The manufacture method of  claim 1 , wherein the middle line portion of the first transmission line is disposed circuitously on the second substrate to form an arch. 
     
     
         3 . The manufacture method of  claim 1 , wherein the middle line portion of the first transmission line is bent on the second substrate to form an angle. 
     
     
         4 . The manufacture method of  claim 1 , wherein the display device mother substrate further includes a third substrate connected to the first substrate, and the manufacture method further comprises disposing an end line portion on the first substrate and the third substrate before the cutting step 
     
     
         5 . The manufacture method of  claim 4 , wherein the step of cutting the display device mother substrate further comprises separating the first substrate from the third substrate to separate the end line portion on the first substrate from the end line portion on the third substrate.
