Abstract
A method of making accurate alignment layers in a liquid crystal display (LCD) cell is provided so that the LCD seal band can be placed as close to the pixel as possible. This method is implemented by ablating the apolyimide film on the glass substrates of the LCD cell to remove the alignment film where the sealing material is to be dispersed later. Thus, the sealing band can butt against the liquid crystal mixture without any clearance. In so doing, the display area is increased, and the reliability of the seal is improved.
