Display device

Abstract

To improve the display quality of a display device, the display device includes a display section and a frame section surrounding a periphery of the display section. A substrate in the display device includes a conductor pattern constituting a circuit section and an insulating film serving as an organic film covering the conductor pattern. The insulating film extends to a peripheral edge of the substrate. A slit, which penetrates the insulating film in a thickness direction, is formed in a corner part of the insulating film. The slit is formed at a position not overlapping the circuit section.

What is claimed is: 
     
         1 . A display device including a display section having a rectangular shape and a frame section surrounding a periphery of the display section, the display device comprising:
 a first substrate having a first surface;   a second substrate having a second surface opposing the first surface of the first substrate; and   a display functional layer arranged in the display section between the first substrate and the second substrate,   wherein the frame section has four side portions along each straight side of the display section, and corner portions between successive the side portions,   the first substrate includes a light shielding film on the first surface,   the second substrate includes a plurality of conductor pattern, and a first organic film covering the conductor pattern,   the light shielding film extends to a peripheral edge of the first substrate on the frame section,   a first slit, which penetrates the light shielding film in a thickness direction, is formed in each of the corner portions, the first slit extends to peripheral edges of the light shielding film in the corner portion, and   a light shielding member is formed at a position overlapping the first slit on the corner portion on the second surface.   
     
     
         2 . The display device according to  claim 1 , wherein the light shielding member is made of the same metal of the conductor pattern. 
     
     
         3 . The display device according to  claim 1 , wherein a light shielding film composed of an organic material. 
     
     
         4 . The display device according to  claim 1 , wherein the first organic film extends to a peripheral edge of the second substrate on the frame section. 
     
     
         5 . The display device according to  claim 1 , wherein a plurality of the first slit are formed in the corner portion. 
     
     
         6 . The display device according to  claim 5 , wherein the area of the light shielding member is larger than the opening area of the first slit. 
     
     
         7 . The display device according to  claim 1 , wherein the display device is a liquid crystal display.
