description 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.
