摘要： A liquid crystal display device having a sealing material close to display area while maintaining a uniform liquid crystal cell gap is disclosed. The liquid crystal display comprises two transparent electrode substrates having a trench near the display area to stop the sealing material overflowing to display pixels. Thus, the effective display area of a liquid crystal display device is increased by dispensing a sealing material to a trench area at a predetermined position surrounding the display area. A spacer used in the sealing material is larger in size than that used in the display area to compensate the depth of the trench. After the liquid crystal is injected into the space surrounded by the substrates and a sealing material, a uniform liquid crystal cell gap over the entire display area is obtained. The liquid crystal display device thus obtained results in a closer distance between the sealing material and display area without any unevenness in color over the entire display area, and lends itself very useful as unit display device or as one of the panels in a tiled liquid crystal display device.

摘要： 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.

摘要： An ODF liquid crystal display panel is formed of a pair of mutually spaced-apart substrates. A liquid crystal layer is contained between the substrates. A first sealing member joins the substrates and defines an enclosed non-peripheral region in which the liquid crystal is contained. A second sealing member also joins the substrates. The second sealing member has a plurality of breaks, and is positioned inside the non-peripheral region defined by the first sealing member and divides the non-peripheral region into a display region and a buffer region in fluid communication with the display region. The gap between the substrates in the buffer region is larger than the gap between the substrates in the display region. The panel is formed by forming drops of liquid crystal in the display region and then joining the substrates using the sealing members. Excess liquid crystal flows through the breaks of the second sealing member into the buffer region. Any vacuum bubbles are formed in the buffer region and not in the display region. A black matrix area is preferably provided in a peripheral area of one of the substrates and the buffer region is preferably positioned in the black matrix area.

摘要： The display area of a liquid crystal display cell is increased by placing conductive epoxy within the boundary which seals the liquid crystal to connect the top glass plate with the bottom glass plate, in contrast with the conventional method of making the electrical connection outside the display area. The conductive epoxy is dispensed in areas not occupied by the liquid crystal patterns. The conductive epoxy can be in the form of particles of spheres or rods serving as spacers for maintaining the gap dimension between the two glass plates. The conductive epoxy can also be integrated with the boundary sealing epoxy or fill a notch cut in the boundary sealing epoxy.
