Touch panel including bent wire in flexible area and display panel including the touch panel

Abstract

A touch panel including: a base substrate including a flexible area; a touch sensing part disposed on the base substrate; and a wiring part disposed on the base substrate. The wiring part includes a bent portion that is bent at least once in a direction that is not parallel to a top surface of the base substrate in the flexible area.

What is claimed is: 
     
         1 . A touch panel comprising:
 a base substrate comprising a first rigid area, a flexible area, and a second rigid area, wherein the first rigid area, the flexible area, and the second rigid area are sequentially arranged in a first direction;   a wiring part extending across the first rigid area, the flexible area, and the second rigid area in a peripheral region of the base substrate, wherein, in the flexible area, the wiring part comprises a first wire and a second wire;   a first insulating layer comprising first protrusions extending in a second direction different from the first direction;   a touch sensing part disposed in a sensing region of the base substrate, wherein the peripheral region is disposed outside the sensing region; and   a pad disposed in the second rigid area of the peripheral region, wherein the wiring part connects the pad and the touch sensing part,   wherein the first wire comprises a removed portion in the flexible area,   wherein the first protrusions overlap the removed portion of the first wire, and   wherein the second wire covers the first protrusions and the first wire in the flexible area.   
     
     
         2 . The touch panel of  claim 1 , wherein the second wire contacts the first protrusions and the first wire in the flexible area. 
     
     
         3 . The touch panel of  claim 2 , wherein the second wire contacts the base substrate between the first protrusions. 
     
     
         4 . The touch panel of  claim 3 , further comprising:
 a second insulating layer comprising second protrusions extending in the second direction,   wherein the second protrusions are disposed in the sensing region.   
     
     
         5 . The touch panel of  claim 4 , further comprising:
 first blocks overlapped with the second protrusions in the sensing region; and   a first bridge electrically connecting the first blocks.   
     
     
         6 . The touch panel of  claim 5 , wherein the first blocks and the first bridge are integrally formed. 
     
     
         7 . The touch panel of  claim 6 , further comprising:
 second blocks covered by the first insulating layer in the sensing region; and   a second bridge electrically connecting the second blocks.   
     
     
         8 . The touch panel of  claim 7 , wherein the second bridge contacts the second blocks through contact holes of the first insulating layer. 
     
     
         9 . The touch panel of  claim 8 , wherein the first wire, the first blocks, the first bridge, and the second blocks are formed of a same material. 
     
     
         10 . The touch panel of  claim 7 , wherein the second bridge extends across the first bridge. 
     
     
         11 . The touch panel of  claim 4 , wherein the second protrusions comprise a dent portion extending in a third direction different from the first and second directions.
