。2. Description of the Related Art A plan view and a sectional view of a typical liquid crystal display panel are shown in FIGS. 4 and 5, respectively. As shown in Figures 4 and 5,
Upper substrate 1. Electrodes 3 and 3b are formed on the lower substrate 2 by vapor deposition or the like, and then alignment films 4a and 4b are formed thereon by offset printing, and after curing, an alignment treatment is performed. Next, a plurality of cylindrical or spherical spacers 5 are arranged on the lower substrate 2, and a sealing material 6 such as epoxy resin is applied to the upper substrate 1 in a substantially ring-shaped screen mark W1. At this time, an injection port 10 is formed so that liquid crystal can be injected later. These two substrates are attached to an alignment device so that the alignment films 4a and 4b face each other, aligned and bonded together, and pressure is applied so that the distance between the upper and lower substrates is set according to the size of the spacer 5. Then remove it from the alignment device and hold it at 150°.
It was left in a hot air circulation oven set at C for 2 hours to harden the sealing material 6 and completely adhere and fix the upper and lower substrates 1.2.
After the liquid crystal 8 is injected through the inlet 10, it is sealed with a sealing material 9.

る電極３Ｌ。Problems to be Solved by the Invention In such a conventional structure and manufacturing method of a liquid crystal display panel, after the alignment of the two upper and lower substrates 1 and 2 is completed, they are pasted together, removed from the alignment device, and then processed. In order to harden the sealing material 6 by leaving it in a hot air circulation oven for a certain period of time under pressure, the upper and lower substrates 1 and 2 of the liquid crystal display panel are misaligned, and the opposing faces formed on the upper and lower substrates 1 and 2 are caused to shift.

に設定することを目的とする。There was a problem in that color shift occurred in the image display due to the shift of 3b. Although it is still possible to increase the viscosity of the sealing material 6 to solve this problem, this method would cause the distance between the upper and lower substrates 1 and 2 to be larger than the value set by the spacer 5, and the voltage applied to the liquid crystal 8 would be increased. There was a problem in that the electric field decreased, leading to a decrease in contrast. The present invention has been made in view of the above problems, and it is an object of the present invention to set the upper and lower substrates of a liquid crystal display panel at accurate and stable positions and intervals by using a simple configuration and changing the manufacturing method.

In FIG. 1, two substrates 1.2 are bonded together after being aligned in an alignment device, and pressure is applied to the upper substrate 1 side of pressure members 13iL and 13b included in the mechanism of the alignment device. The sealing material 6 is compressed and pressurized by a rubber material 14 having a seal pattern shape with a width of about 2 mm attached to the member 131L and a pressure member 13b on the lower substrate 2 side, and both substrates 1.2 The gap is maintained at a predetermined size determined by the spacer 5.

When applying a small amount of UV curable resin, if the tip of the dispenser needle 11 first hits only one of the top and bottom, there is a possibility that a sufficient amount of UV curable resin will not be applied to the stepped corner. If the tip of the dispenser needle 11 is pressed against the corner of the step and then the UV-cured resin is discharged from the tip of the dispenser needle 11 and applied, the coating position and amount are stable, and it is also compatible with automation.
