This is a substrate specifically limited to being glass (hereinafter referred to as a glass substrate) for a liquid crystal display element.The reason why the present invention is limited to the glass substrate 1.2 is that in the current manufacturing technology, the resin U plate This is because the viscosity in all aspects such as flatness is insufficient to form the liquid crystal display element, and it is not possible to manufacture the liquid crystal display element that fully satisfies the specifications. Applying the present invention to resin substrates after the above conditions are satisfied does not significantly change the gist of the present invention.Glass Substrate 1

とすることができる。b) The reference numeral 7 in FIGS. 1 and 2 is a position fixing member, and when the conventional flat type liquid crystal display element is pressed facing each other, the registration mark is placed at an appropriate position. By setting alignment marks called such as
Although it is possible to confront the object at an accurate position d relatively easily, in the method of the present invention, since the curving step is performed after the confrontation, it is difficult to maintain an accurate opposing position. The position fixing member 7 is provided for this reason, and is placed on either one of the glass substrates 1.2 by an appropriate method such as silk screen printing using an ultraviolet curing resin. This state is shown in FIG. 3, where the glass substrate 1 is disposed approximately at the center of the curved side and at both ends near where the sealing material 3 is disposed. At this time, the sealing material 3 is made of thermosetting resin. By doing this, the sealing material 3 and the position fixing material 7 can be cured separately. Therefore, first, the glass dam plate 1.2 is placed facing each other in the correct position in a flat state, and then exposed to UV light. After each of the glass U plates 1.2 is fixed at an accurate position, the glass U plates 1.2 are set in the bending jig 5.6 and curved, and the sealing material 3 is cured by heat. Thereby, the positions where the respective glass plates face each other can be made extremely accurate.

A groove 62 is provided at a position corresponding to the edge of the glass substrate that is a portion other than the display surface, and the same adhesive 9 as the sealing material 3 is applied to the side of the glass substrate 2 in advance. Curved reinforcement material 8 made of stainless steel, etc.
are set, and at the same time as the bending process, the reinforcing material 8 is also bonded to the outer surface of the liquid crystal cell as shown in FIG. By doing so, it is possible to reduce the deformation caused by the springback phenomenon due to the elasticity of the glass substrate 1.2 and maintain the liquid crystal cell in the correct shape.

生ずるところとなる。c) The process of bending the glass substrate 1.2 described above is performed by adjusting the thickness of the usable glass material, since the glass substrate 1.2 is strong and easily damaged by surface stress. is limited to a narrow range, and according to the results of tests conducted by the inventor, it was found to be less than 0.2 m, preferably 0.05 m. If it is thicker than this, it is likely to cause the damage described above, and if it is thinner than this, there are basic requirements such as parallelism of each of the glass substrates 1 and 2 against thermal expansion of the liquid crystal material sealed inside. It is difficult to maintain this, and the performance as a liquid crystal display element becomes difficult.
