Referring to Figure 5, a first preferred embodiment of the present invention will be described. First, a specific form of the present invention will be described. In order to position the stamper 1 〇 1 forming the fine concavo-convex pattern or hologram in a vacuum, a vacuum device 106 capable of forming a vacuum is provided on the upper metal mold 104 to which the stamper 101 is attached. At this time, in order to maintain the peripheral temperature of the stamper 101 constant, the heating means 105 is disposed behind the stamper of the upper metal mold 1〇4. Further, when the lower metal mold 1〇3 which forms the remaining outer shape of the light guide plate is moved in the A direction and is completely tightly bonded to the upper/metal mold 104, an injection material which can be injected into the parent is formed.

The upper and lower metal molds 1〇4, 103 thus constructed are completely close gentlemen

1247944

In order to prevent the rapid temperature drop caused by the high-temperature injection material of the light guide plate from the injection port 1 〇7, the gentleman is injected into the /heat device 105 in order to make the adhesion pressure. The temperature of the mold metal mold 1 〇 4 is approximately the temperature of the shot material, and is heated in advance to maintain the temperature. In this way, since the temperature difference between the contact surface of the stamper 101 and the material to be ejected is 昱, the injection material 100 is injected into the mold to prevent a sharp drop in temperature change. Therefore, the light guide plate 1 in which the fine pattern is completely formed can be manufactured. 2. That is, since the temperature of the injection material is maintained at the temperature necessary for the formation during the forming, the forming system is completed as shown in the enlarged portion of Fig. 5, and the stamper is 1〇1. The fine pattern is surely formed on the light guide plate 102. - As shown in Fig. 5, the heating device 1〇5 can be placed at the rear of the stamper 1〇1 by attaching the gold j, 1, 04 to the upper stamper to set a high-temperature fluid such as oil or water. The method of circulation (from C to D), or the way of the hot line, etc., is implemented. ^ ^ In the case where a pattern is formed on one side of the V-light plate, it can be completed on both sides of the light guide plate by providing the same heating device, vacuum device, and stamper ' on the lower metal mold 103 as the upper metal mold 1〇4 Form the desired pattern. Thus, the stamper used in the manufacture of the light guide plate can be manufactured in accordance with the light guide plate to be manufactured. That is, as shown in Fig. 3, in order to form a conventional fine pattern having a hemispherical shape, a quadrangular shape, a triangular shape, and a mesa shape, the manufactured stamper can be used according to the process shown in Fig. 3. Further, in order to manufacture the holographic light guide plate proposed by the applicant of the present application in the prior application, a stamper for the holographic light guide plate may be used. Further, the stamper for the hologram light guide plate can also be manufactured by the method suggested in the present application.

V. INSTRUCTIONS (10) Next, a method of manufacturing a holographic stamper will be described in detail. The hologram layer of the holographic light guide plate has a function of making the scattering on the light source side smaller, the 纟A emission is smaller, the scattering from the light source side is larger, the diffraction is larger, and the distribution of the entire light guiding light is uniform. In order to manufacture a holographic stamper, two methods of manufacturing using a photomask and a method of not using a photomask can be used. First, a method of manufacturing a holographic platen using a photomask will be described. The g-layer and the photo-mask used in forming the hologram layer are shown in Fig. 1A and Fig. 9B. The reticle pattern of Fig. 9 is a circular (or polygonal) pattern as a whole, and the area density of the pattern on the light source side (A) is low, and the pattern of the pattern farther from the light source side is The higher the density; the interior of the pattern forms a transparent shape, while the other portions form a mask i that blocks the opacity of light. The Fig. 9B is a reticle 2 in which the light transmission at the light source side (A) is relatively low, and the light transmittance at a farther distance from the light side (B-C direction) is higher. A method of manufacturing a hologram plate using such a photomask will be described with reference to the drawings. First, the laser beam emitted from the laser beam 5 is enlarged by the lenses 501 and 502, and the thus-expanded laser beam is incident on the diffusion plate 503 (Gr〇und glass diffuser) to be diffused. Further, a transparent substrate 5 〇 5 coated with a sensitizer 506 is disposed at a distance L from the diffusion plate 5 〇 3, and a photomask 504 is attached to the surface on the side where the sensitizer is applied (Fig. 9A). The reticle 1 or the reticle 2) of FIG. 9B exposes the sensitizer 506 to the laser beam scattered from the diffusion plate 503. Due to the configuration of the foregoing apparatus, the case of the photomask 1504 as shown in Fig. 9A is used. 'With the transparent portion of the photomask, the laser beam diffused from the diffusion plate 503 can sensitize the sensitizer, after a certain period of time passes. After the development process, the illuminance of the portion irradiated by the laser beam as in the form of the reticle shown in Fig. 9A

Page 14 1247944 Case No. 89117993 Lunar Amendment V. Invention Description (11) One dose 'in accordance with the speckle 1 e pattern #, to form a hologram 8〇〇 as shown in Figure 11A . That is, the hologram plate 80 1 in which the hologram 8 排列 is arranged is formed only inside the pattern in accordance with the pattern of the reticle used. In the case of exposure using the mask 2 shown in FIG. 9B, the light transmits the hologram of the south portion, and since the amplitude modulation 80 2' of the unevenness is higher, the diffraction efficiency is formed higher; and the hologram which transmits the lower portion is due to The amplitude modulation of the concave and convex is 80 2 '', so that the diffraction efficiency is formed lower, and the hologram plate 801 whose diffraction efficiency is gradually decreased from A to B as shown in FIG. The manufacture of the holographic stamper will be described below with reference to Fig. 12. When electroless plating is performed on the hologram plates 801, 801' manufactured as described above, a metal film 094 (321-322) is formed on the upper surface of the hologram 901 and the sensitizer 901 which is not exposed by the laser beam; The film 906 is separated from the substrate 903, and the pattern of the hologram 902 on the upper surface of the substrate/0 0 3 is reproduced in a positive pattern 90 5 to form a stamp 904 (S23) of the metal master. Fig. 13 is a diagram showing an enlarged convex portion of the stamper 904. Next, a method of manufacturing another hologram using the above-described photomask 1 and mask 2 will be described with reference to Figs. 14A and 14B. First, the laser beam emitted from the laser 600 is expanded into a diameter of 5 to 2 0 using the lenses 601 and 602 having a small diffusion angle, and the thus-expanded laser beam is incident on the diffusion plate 6 〇 3 (Ground glass diffuser) to spread it. Moreover, a transparent mask 605 which is provided with a sensitizer 605 is disposed at a distance L from the diffusion plate 6 0 3 - a photomask 604 is attached to the surface on the side where the sensitizer is applied (the mask of Fig. 9A). 1 or the mask 2 of Figure 9B). The substrate 605 is attached with a moving device omitted from the drawing, and can be moved in the up and down and left and right directions by control of a computer or the like. When the exposure is performed, the substrate 605 is moved to the left and right and up and down directions.

At this time, the substrate is exposed while moving in the left and right and up and down directions, and the entire substrate is exposed to the laser beam. The moving direction, for example, can be formed from (1) - (2) - (3) ^ (4) as shown in Fig. 14B. In the configuration of the above apparatus, in the case where the mask 1 shown in Fig. 9A is used, the laser beam diffused from the diffusing plate 6〇3 through the transparent portion of the mask 604 can sensitize the photosensitive agent. After a certain period of time and after the development process, as in the form of the reticle shown in Fig. 9A, the sensitizer irradiated by the laser beam is etched according to the speckle pattern of the laser beam to form the eleventh. The hologram 800 shown in Figure A. Namely, the hologram 8 〇 1 in which the hologram 8 排列 is arranged is formed only inside the pattern in accordance with the pattern of the reticle used. When the reticle 2 shown in Fig. 9B is used for exposure, the light transmittance of the hologram of the vehicle/high portion is higher due to the amplitude modulation of the unevenness 8 〇 2, so that the diffraction efficiency is relatively low, and the transmission is relatively low. In the hologram, since the amplitude modulation of the concave and convex is lower than 80 2π, the diffraction efficiency is formed lower, and the hologram plate 8〇1 which is gradually reduced in the direction from A to B as shown in FIG. ,. Thus, the substrate 60 5 to which the reticle 1 or the reticle 2 is attached and to which the sensitizer 606 is applied is moved up and down and left and right to manufacture a hologram plate, even if the diffusion angle of the laser beam is small' and even the power (output) is higher. The small laser also has the advantage of making a large area of uniform holographic plate. Further, the process of producing a holographic stamper by electroless plating using the hologram plate thus produced can be the same as that described above with reference to Fig. 2. Next, a method of manufacturing another hologram using the above-described photomask 1 and mask 2 will be described with reference to Figs. 15A and 15B. First, using the lenses 701 and 702 having a small diffusion angle, the laser beam emitted from the laser beam 7 is expanded into

5 to 20 legs, and the thus-expanded laser beam is incident on the secondary element scanning, and then the laser beam scanned from the binary scanning device is passed through the lens 707 (Ground glass diffuser) The upper scan causes it to spread. Further, the lens means 707 includes at least one lens and can withstand the diffusion angle of the laser beam scanned from the secondary scanning device. At a distance L from the diffusion plate 703, a transparent period plate 705 for applying the sensitizer 706 is disposed, and a mask 7 0 4 is attached to the side surface of the sensitizer (the reticle of the 9A drawing) 1 or 9B picture mask 2). Further, the secondary scanning device 7〇6 is connected to a control device such as a computer omitted in the drawings, and since the scanning beam is automatically controlled while scanning the laser beam, the entire diffusion plate 703 can be uniformly scanned. Since the binary scanning device 706 can employ a raster scan or a vector scan (vect〇r scan), the scanning direction can be selected in accordance with the necessity of use. Fig. 15B is an illustration of the scanning direction of the secondary scanning device. That is, the scanning beam A-B, C-D direction [(1) - (2) - (3) - (4)] '' and the entire substrate are exposed to the light scattered from the diffusion plate 7 〇 3 Beam. Further, since the lens means 707 can be used, the incident angle of the beam of the incident diffusing plate 703 is made almost perpendicular, so that the efficiency of light can be improved. According to the configuration of the foregoing apparatus, the laser beam diffused from the diffusing plate 703 through the transparent portion of the reticle 1 can sensitize the sensitizer, after a certain period of time and after the development process, as shown in Fig. 9A. In the form of the reticle, the sensitizer irradiated by the laser beam is engraved in accordance with the speckle 1 e pattern of the laser beam to form a hologram 800 as shown in Fig. 11A. Namely, the hologram plate 8 01 in which the hologram 8 〇 is arranged is formed only inside the pattern in accordance with the pattern of the reticle used. Using the reticle 2, the light transmits a relatively high portion of the hologram,

Invention Description (14) The amplitude modulation of the bump is 8〇2, which is higher, so the diffraction efficiency is higher; while the lower part of the hologram is transmitted due to the bump The amplitude modulation 80 2 2π is lower, so that the diffraction efficiency is formed lower, and the hologram plate 801 whose diffraction efficiency is gradually reduced from the Α to the Β direction as shown in Fig. 11 is obtained. And using the hologram plate thus manufactured, performing electroless plating to produce a holographic stamper, the laser beam can be obtained by referring to FIG. 12 and the same as ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ By manufacturing the hologram plate by the two-dimensional scanning, even if the diffusion angle of the laser beam is small, and even a laser having a small power (output), there is an advantage that a uniform holographic plate having a large area can be manufactured.

High ^ light guide plate. Hereinafter, a method of manufacturing a stamper for such a holographic light guide plate will be described. Next, a method of manufacturing a hologram plate without using a photomask will be described based on Figs. 14A and 14B and Figs. 15A and 15B. In the case of the configuration of the first 4 A, the photomask 604 provided before the sensitizer is removed, and the susceptor-coated substrate 605 is left-right and up-and-down (Fig. 14B (1) - (2) - (3) When -(4)] is moved, since the moving speed can be adjusted, the diffraction efficiency of the hologram after the shadow can be adjusted. That is, since the moving speed is faster, the diffraction efficiency after development is lower, and the portion where the moving speed is slower, the diffraction efficiency after development is higher, so that it can be manufactured as shown in Fig. 11B. The hologram plate 801 whose diffraction efficiency in the B direction is gradually reduced. The same applies to the case of Fig. 15A, except that the photomask 704 provided before the photo-sensitive agent is removed, and the laser beam is scanned on the diffusion plate 703 by the secondary scanning device 706 to perform exposure.
