ル、11は切断マーカ、12は液晶注入口である。Liquid crystal devices are currently widely used in liquid crystal TVs and the like, and research and development are being vigorously conducted for downsizing and high definition. In order to realize compactness and high definition without changing the substrate size, it is necessary to make the image display area as large as possible within the substrate. Therefore, in sticker printing for overlapping two substrates, a high-precision positioning is required because the seal does not overlap the display area and does not overlap the scribe line at the time of cutting. As shown in FIG. 4, the conventional seal printing method includes a stage 6 for adsorbing a substrate and a substrate fixture 5 for fixing the substrate, and a screen 2 for printing a seal is installed on the upper part thereof. In the figure, reference numeral 16 denotes an adjusting screw. The position of the substrate on the stage 6 is fixed by the substrate fixing device 5 and sucked, and a seal is printed by a screen printing method. Further, at that time, in the seal heating and firing after the liquid crystal element is overlapped, based on the dimensions of the outer shape of the substrate so that the seal portion does not overlap the scribe line 17 and the pixel region 13 shown in FIG.
This was done in consideration of the machine accuracy of the printing press, the work accuracy, the seal width, etc. In the figure, 9 is a peripheral seal, 10 is an auxiliary seal, 11 is a cutting marker, and 12 is a liquid crystal injection port.

が低下するという問題があった。In conventional seal printing, printing is performed in consideration of the mechanical accuracy of the printing machine, the work accuracy, the seal width after firing the seal, and the like, based on the dimensions of the outer shape of the substrate. However, the conventional printing method has a disadvantage that it takes time to position the seal printing. In addition, if the printing position is shifted, the seal is applied to the scribe line 17 and a cutting failure occurs, or the sealing is applied to the pixel region 13 to cause a display failure.

The position of the seal printing is determined. That is, the laser light emitted from the laser light oscillator 1
The position of the laser light oscillator 1 is determined so as to pass through the laser transmission port 3 having a diameter of 1.0 mm formed in the optical receiver 8 and enter the light receiver 8. 14 is a squeegee. Next, a substrate O which has been subjected to rubbing treatment by applying polyimide as an alignment film is adsorbed and fixed on the stage 6. On the substrate O, a seal printing marker 4 having a diameter of 1.0 mm is formed of a chrome film outside the cutting marker 11. The laser beam that has passed through the laser transmission port 3 of the seal plate 2 is blocked by the marker 4 for seal printing, and is input to the light receiver 8. The stage 6 is moved and positioned by the movement adjuster 15 so that the output of the light receiver 8 is minimized, and a seal pattern is printed on the substrate O by a screen printing method. Although a large number of liquid crystal elements were manufactured by this method, the seal did not overlap the scribe line 17 or the pixel region 13 even after the seal was fired, and no cutting failure or display failure occurred.

かった。In the figure, a laser beam emitted from a laser beam oscillator 1 passes through a laser transmission opening 3 having a diameter of 1.0 mm on which a sealing plate 2 is formed and enters a light receiver 8 so that the laser beam oscillator 1 emits laser light.
Determine the position of. Next, a substrate O coated with polyimide as an alignment film and subjected to a rubbing treatment is adsorbed and fixed on the stage 6. On the substrate O, a seal printing marker 4 having a diameter of 1.0 mm is formed of a chrome film outside the cutting marker 11 shown in FIG. The laser beam that has passed through the laser transmission light 3 of the seal plate 2 is shielded by the marker 4 for seal printing and is input to the light receiver 8. The laser light oscillator 1 and the seal plate 2 are moved in parallel by the movement adjuster 15 so that the output of the light receiver 8 is minimized, and positioning is performed. A seal pattern is printed on the substrate O by a screen printing method.

ず、歩留が向上するという効果を有する。Further, since a marker for sticker printing is formed on the substrate and the amount of light transmitted from the periphery of the marker is detected, the optimum position for sticker printing is determined.
Accuracy of positioning for sticker printing has been improved, and the time required for several tens of minutes has been reduced to several seconds, and the problem that the seal is applied to the scribe line or the pixel area after manufacturing the liquid crystal element has been eliminated, resulting in poor cutting. No display failure occurs, and the yield is improved.
