Liquid-Crystal Display

Abstract

A liquid-crystal display, including a first substrate including a pixel electrode, a black matrix, and a plurality of metal traces disposed thereon. A second substrate includes an opposite electrode, a light-shielding layer disposed in a shielding area, and the light-shielding layer being adjacent to a side of a display area. A sealant adherently secures the first substrate and the second substrate, which is disposed in a sealant dispensing area and surrounding a side of the light-shielding layer, wherein the sealant dispensing area is in the shielding area. A liquid-crystal layer is interposed between the first substrate and the second substrate and surrounded and sealed by the sealant. A color filter is disposed on the first substrate, wherein the light-shielding layer includes a black photoresist, and the light-shielding layer overlaps the sealant dispensing area.

What is claimed is: 
     
         1 . A liquid-crystal display, including a display area and a shielding area surrounding the display area, wherein the shielding area has a total transmittance of equal to or less than about 50% and greater than 0, the liquid-crystal display comprising:
 a first substrate including a pixel electrode, a black matrix, and a plurality of metal traces disposed thereon, wherein the pixel electrode is disposed in the display area, and the plurality of metal traces are disposed in the shielding area and electrically connected to the pixel electrode;   a second substrate including an opposite electrode,   a light-shielding layer being disposed in the shielding area, and the light-shielding layer being adjacent to a side of the display area;   a sealant, adherently securing the first substrate and the second substrate, disposed in a sealant dispensing area and surrounding a side of the light-shielding layer, wherein the sealant dispensing area is in the shielding area; and   a liquid-crystal layer interposed between the first substrate and the second substrate and surrounded and sealed by the sealant; and   a color filter disposed on the first substrate, wherein the light-shielding layer comprises a black photoresist, and the light-shielding layer overlaps the sealant dispensing area.   
     
     
         2 . The liquid-crystal display according to  claim 1 , wherein the color filter is adjacent to the pixel electrode. 
     
     
         3 . The liquid-crystal display according to  claim 1 , wherein the shielding area has gradient decreased light transmittance. 
     
     
         4 . The liquid-crystal display according to  claim 1 , wherein the plurality of metal traces are covered by the light-shielding layer and the sealant. 
     
     
         5 . The liquid-crystal display according to  claim 4 , wherein the plurality of metal traces and the sealant are direct contact with each other. 
     
     
         6 . The liquid-crystal display according to  claim 1 , wherein the sealant comprises epoxy resins of various colors, polyacrylate resins, poly(urethane acrylates), carbon powders, or a combination thereof, which are doped with metal particles, ceramic particles, plastic particles or a combination thereof. 
     
     
         7 . The liquid-crystal display according to  claim 1 , wherein the sealant area has a light transmittance of less than or substantially equal to about 50% and greater than 0 or has a total light absorption of about 50% to 100% of the light absorption of the light-shielding layer. 
     
     
         8 . The liquid-crystal display according to  claim 1 , the light-shielding layer has an optical density of greater than about 3.5.
