Display panel and manufacturing method of the same

Abstract

Provided are a display panel which can detect a touch position derived from a user's touch and can prevent erroneous touch position data from being generated even when an erroneous connection to a position sensing line is present due a processing deviation or a cell gap deviation, and a manufacturing method of the same. The display panel includes a first substrate, a first sensor pad that is formed on the first substrate, a second sensor pad that is spaced apart from the first sensor pad, a second substrate that is disposed to face the first substrate, a first sensor spacer that is formed on the second substrate to overlap the first sensor pad and protrudes toward the first substrate, a second sensor spacer that is formed on the second substrate to overlap the second sensor pad and protrudes toward the first substrate, and a sensor electrode that is formed on the first sensor spacer and the second sensor spacer to overlap the first sensor pad and the second sensor pad, wherein the second sensor spacer protrudes toward the first substrate more than the first sensor spacer does.

What is claimed is: 
     
         1 . A display panel comprising:
 a first substrate;   a second substrate that is disposed to face the first substrate;   a common electrode that is formed on the second substrate;   a first sensor spacer that is formed on the first substrate and protrudes toward the second substrate;   a second sensor spacer that is formed on the first substrate and protrudes toward the second substrate;   a first sensor pad that is formed on the first sensor spacer;   a second sensor pad that is formed on the second sensor spacer and is spaced apart from the first sensor pad; and   a sensor electrode that is formed on the second substrate to overlap the first sensor pad and the second sensor pad,   wherein the second sensor spacer protrudes toward the second substrate farther than the first sensor spacer.   
     
     
         2 . The display panel of  claim 1 , wherein a distance between the second sensor pad and the sensor electrode is smaller than a distance between the first sensor pad and the sensor electrode. 
     
     
         3 . The display panel of  claim 2 , wherein a difference between the distance between the second sensor pad and the sensor electrode and the distance between the first sensor pad and the sensor electrode is 0.1 μm or greater. 
     
     
         4 . The display panel of  claim 2 , wherein the sensor electrode and the second sensor spacer contact each other with the second sensor pad disposed therebetween.
