After setting the upper and lower substrates in the device, by removing the air inside the device, the flexible part presses the upper and lower substrates against the transparent part at atmospheric pressure, resulting in uniform pressure bonding and air distribution. without being influenced by the elements,
By applying ultraviolet rays, it is possible to seal the surface with good surface hardening.

は生じなかりた。[Practice 111] Spacers were uniformly dispersed on one substrate, and a radical curing type ultraviolet curable resin was printed on the other substrate as the sealant 6.
As shown in the figure, set the upper and lower substrates 7 in a vacuum-tight N device,
Due to the degassing through the degassing holes 4, the rubber adsorbent 2 adhered to the frame 5 comes into close contact with the glass plate 1, and the flexible rubber sheet 3 also holds the upper and lower substrates 7 against the glass plate 1. Press it against the plate l with even pressure. Under this condition, the sealant 6 was cured by irradiating ultraviolet rays at 3000 mJ/cm" from the outside of the glass plate 1. By injecting T-liquid crystal into the cell obtained by this method, a liquid crystal display device was obtained. This liquid crystal In the display device, the substrate spacing was uniform (at), and even in the vicinity of the sealant, there was no alignment failure of the liquid crystal due to uncured sealant.
