Two or more wires and a plurality of pads connecting the wires to the outside form a sealing material in which the pads are mixed with spacers having a size inversely proportional to the thickness along the circumference of the first substrate formed at the edge with different thicknesses. A spacer is provided on the front surface of the first substrate, and the second substrate is attached onto the first substrate. Accordingly, in the liquid crystal display device according to the present invention, the size of the mixed spacer is partially formed by changing the method of forming an epoxy therein, thereby eliminating errors caused by uniformly gaps of the liquid crystal cell as a whole, and improving the image on the screen. The transmittances of the lower, left, right and center portions are made the same to improve contrast and brightness.
