20130141677 | LCD, LCD Substrate and LCD Manufacturing Method - The present invention discloses a Liquid Crystal Display (LCD), a LCD substrate and a LCD manufacturing method. The boundary of the substrate, to be coated with alignment liquid, is provided with a boss or a groove which is used to prevent the alignment liquid from diffusing. Because the substrate of the LCD is provided with the boss or groove for preventing the alignment liquid from diffusing, the boss can prevent the alignment liquid from diffusing, and the groove can absorb the diffused alignment liquid. As a result, the alignment liquid is prevented from forming nonuniform boundary on the substrate with surface section difference, and the uniform boundary is formed; furthermore, the boundary of the active area of the LCD further deflects to the alignment layer, and the range of the active area is expanded. Under the action of the blockage by the boss or groove, the boss or groove can deflect to the sealant area, i.e. the boundary of the alignment layer deflects to the sealant area, thereby further expanding the range of the active area. | 06-06-2013 |
