A mask plate for printing a plasma display printed material for filling and coating in a trench, and a supply method for a plasma display fluorescent material using the mask plate.

[Prior art]

Plasma display devices are arranged in such a manner that phosphors r, g, and b of each color are displayed by applying a plasma between a rear glass substrate disposed on the rear surface and a front glass substrate disposed on the front surface. In other words, the three primary colors of red (R), green (G), and blue (B) are fluorescently displayed on each of the scanning line intervals on the back glass substrate. After dividing the three honeycomb or stripe-shaped filling accommodating groove portions, the fluorescent materials corresponding to each color are inserted in each of the filling accommodating groove portions, and MgO is interposed above the filling accommodating groove portion. After forming a protective layer made of SiO 2 and a dielectric layer made of SiO 2, the electrode conductors supported by the transparent sustain electrodes forming the χη electrode and the γη electrode are arranged on the front glass substrate side, and formed into fluorescent materials R and G corresponding to each color. Between the addresses (B) configured by B and B, a specific color is displayed by applying a plasma. The fluorescent materials R, G, and B in each of the filling and accommodating grooves on the glass substrate of such a plasma display device are mainly made by screen printing -4- 200525575 (2) The filling is inserted into each Within one color, and generally as shown in FIG. 7, the mask plate 100 formed by the printing pattern corresponding to the positioning of each scanning line pitch is aligned with the barrier walls 102 formed on the back glass substrate 101 After aligning the positions therebetween, the masking plate S is wiped by the scraper S to supply the filled fluorescent materials R, G, and B to the predetermined barrier ribs 102. In addition, the mask plate 100 used at this time is provided with a mesh-shaped screen plate (sieve hole) gauze 105, and the squeegee S that wipes the gauze 105 is used to supply the filled fluorescent material R, G, B (paste) to the grooves between the barrier ribs 102

[Summary of the Invention] [Problems to be Solved by the Invention]

However, in the printing structure formed by the traditional mesh-shaped screen plate, that is, the mask plate 100 of the gauze 105, in order to make use of the stretch (flexibility) of the screen mesh as a printing characteristic, There are restrictions on the print size. For example, it may vary depending on the screen size (40/50/60 inches), but only the formation of plasma display devices of XGA level (HD · VG level) can be used. In addition, the opening portion formed by the sieve hole portion of the mask plate 〇〇 itself has a sieve hole relationship, which makes the throughput of the conductive paste unstable, resulting in unevenness due to unstable discharge formation (ripples). ) Disadvantage ° Further, 'in order to make the plasma display device with a more precise display type, when the fineness is increased, a finer sieve should be selected further', so the adjustment range of the coating amount also changes. Narrow, its precision system is more required ° In addition, because of diffusion and printing offset, not only 200525575 (3) contact printing is difficult, but must be in the phosphor (R, G, B paste) (pasle) For the sake of drying after printing, it is necessary to ensure the drying furnace used in each treatment process and the pulp during the drying process. Especially in the screen version, in order to ensure the printing dimensional accuracy, it is necessary to use an aluminum frame element with a printing area of about 2 times. At present, the largest size is 2,500 x 2,500 0 to 2,700 x 3,000, and further 3,300 x 3,500. Etc. (All units are mm). Not only that, but from the perspective of printing accuracy, only about 5,000 paddle scratches can be ensured, the printing durability is insufficient, and the cost reduction cannot be expected. Therefore, the present invention is an invention proposed in view of various problems existing in the conventional device described above, and further uses an opening forming member made of a photosensitive exposure material formed by solidification in an opening portion formed by an opening formed by a metal plate version body. In order to form a more precise opening, even if the width between the mutual wall surfaces is, for example, 5 0 // m, and further, for example, 30 to 3 5 // m, it can supply the fluorescent materials of various colors to the inside of the conductor paste. In addition, the opening forming element can be repeatedly peeled and regenerated, which is effective in reducing the running cost. The metal plate can also be managed and used in the same manner as the gel mask for the penetration specific to the metal plate. It is also very easy to maintain. In other words, by continuously printing and coating various colors of fluorescent materials on the glass substrate that becomes the substrate of the plasma display device, there is no need to perform a drying process with each coating color. The purpose is to provide a masking plate for plasma display fluorescent material printing using a space, reducing electricity costs, and reducing damage to a substrate caused by heat, and a charging method for supplying a fluorescent material for a plasma display using the same. 200525575 (4) [Means for solving the problems] In order to solve the above problems, the plasma display fluorescent plate M printing mask plate 10 of the present invention belongs to a type of screen printing method, which is used to charge and supply each predetermined fluorescent plate. Each of the light plates R, G, and B to a mask plate j filled with the receiving groove portion 3 defined by the wall surface 2 on the substrate 1 of the plasma display device is characterized by the metal formed in the opening of the metal plate body 11 The pattern opening 12 includes a photosensitive emulsion 13 formed by coating and solidified on the metal plate body 11 after the metal pattern opening 12 to form an opening having an opening area not larger than that of the filling receiving groove portion 3 to form a filling pattern opening 14. The filling pattern opening 14 is located in the metal pattern opening 12 and its opening area will not be larger than that of the metal pattern opening 12. It can be formed by high-precision openings. In addition, the opening can also be formed with the metal pattern. The openings 1 2 are almost the same size. In addition, the filling pattern openings 14 may be divided by the partition sheet portion 15 corresponding to the partition portion partitioned by the partition wall 5 partitioning the filling storage groove portion 3 in the longitudinal direction. In addition, on the printing surface side of the photosensitive emulsion 1 3 coated and solidified on the metal plate body 11, it is possible to contact other filling storage grooves that are not coated with a doctor blade and supplied to the fluorescent materials R, G, and B. The spacer portion 21 on the barrier wall 2 of the groove portion 3 is formed in a protruding shape. In addition, between the spacer portions 21, a configuration in which the gap avoidance region 22 is formed at the opening surface of the filling receiving groove portion 3 may be employed. In addition, the charging method for the fluorescent materials R, G, and B of the plasma display display using a masking plate for the printing of fluorescent materials for the display of fluorescent materials belongs to a method of using -7- 200525575 (5) The filling pattern openings 14 arranged at specific intervals in the longitudinal direction of the groove portion 3 are used for the screen printing method of the mask plate I 0 for fluorescent material printing to fill the barrier wall supplied to the glass substrate 1 of the plasma display device. 2 Each of the filling and accommodating groove sections of the zone 3, the specific fluorescent materials r, G, and b, are specified in the length along the length of the receiver_receiving groove section 3, and the mask plate for fluorescent material printing is moved slightly. After filling the supply method.

The mask plate 10 for fluorescent material printing at this time is tied to the metal pattern opening 12 'which is opened in the metal plate body 11 and can be formed by coating and solidified in the metal plate body 1 1 at the position of the metal pattern opening 13 at the metal pattern opening. After 12, the filling pattern opening 14 having an opening area not larger than the filling filling groove portion 3 is formed. In addition, the filling pattern opening 14 can also be formed by using the rectangular direction of the filling storage groove portion 3. The divided partition pieces 15 are divided.

The mask plate for the plasma display fluorescent material printing of the present invention configured as described above, and the method for charging and supplying the plasma display fluorescent material using the mask version are provided on the glass substrate 1 in the filling receiving groove portion 3 For the mask plate 10 prepared different from each color, the filling pattern opening formed in the opening of the mask plate 10 is aligned to each filling groove portion 3, and then a scraper plate ( squeegee) S. The fluorescent materials R, G, and B of each color are coated and formed in a fine-width, fine-diameter filling and containing groove portion 3 to sufficiently fill and supply sufficient fluorescent materials R, G, and B. The photosensitive emulsion 1 3 coated on the metal plate body 1 1 is formed by openings formed in the thick metal pattern openings 12 of the metal plate body 11 to form a high-density filling pattern opening 14 of a specific size, and filling Pattern opening 1 4 pairs-8-200525575 (6) After filling the receiving groove portion 3 with a quasi-minimum width, the fluorescent materials r, G, and B are supplied to the inside thereof. The metal plate body Π itself is a metal pattern opening 12 that forms a core body (c ore) that is filled with the pattern openings 14. In addition, the metal pattern opening] 2 will hold the photosensitive emulsion 1 3 and the solidified emulsion 1 The small and fine filling pattern openings 14 formed by the openings 3 are arranged in the photosensitive emulsion 1 3 portions formed in the closed metal pattern openings 12.

In addition, the partition sheet portion 15 is used to supply the fluorescent materials R, G, and B to the charging unit with high accuracy after maintaining the opening width of the filling pattern openings 14 forming a long line along the rectangular direction.塡 Receiving groove section 3

The photosensitive emulsion 1 3 is coated and fixed on the metal plate body 11. For example, even if it is damaged or worn due to repeated blade coating, the original opening shape of the filling pattern opening 14 is damaged, as long as it is peeled off. After the emulsion coating and plate-making pattern opening process are performed again, the filling pattern opening 14 can be regenerated. The spacer portion 21 is abutted against the barrier walls 2 on both sides of the charging receiving groove portion 3, and even if the solvents R, G, and B contained in the charging receiving groove portion 3 are contained in the charging receiving groove portion 3, The groove portion 3 overflows, and it can also avoid its contact with the mask plate 10, and the drying after the filling of the colors will not cause the solvent to disappear. The colors can be continuous without going through the drying process of each color. After filling, dry once. The filling pattern opening 1 4 is made to have the same size as the metal pattern opening 12 by being opened, and the metal plate body 1 1 itself is treated as light. 9- 200525575 (7) The mask emulsion is applied to the photosensitive emulsion. 1 3 directly forms the filling pattern opening 1 4 ′ to form a precise filling pattern opening □ 14 corresponding to the filling storage groove portion 3.

In addition, the filling supply is constituted by micro-movement along the rectangular direction of the filling storage groove portion 3 of the masking plate 10 for fluorescent material printing during the filling supply by the screen printing method, and the maintenance is maintained by using Filling pattern openings 14 of the opening width of the separator sheet portion 15 sequentially fill the filling material receiving grooves 3 with fluorescent materials R, G, and B that are not supplied in the filling material storage groove portion 3 into the filling material storage groove. Unfilled area of groove section 3. In addition, since the elongated partition piece portion 15 itself is formed to prevent deformation of each opening shape of the filling pattern opening 14, it is possible to maintain a highly accurate opening shape and to withstand repeated use. [Embodiment]

The best mode for carrying out the present invention will be described below with reference to the drawings. The glass substrate 1 on the back of the plasma display device is indicated by the reference numeral 1 shown in Figs. 1 and 2. On this substrate 1, in order to fill each scanning line interval with fluorescent light, red ( The fluorescent materials defined by the three primary colors of R), green (G), and blue (B) form a full-contained receiving groove portion 3 defined by a barrier wall (rib portion) 2. In addition, the address electrodes 4 are arranged in the respective filling accommodating groove portions 3. In the filling receiving groove portion 3 on this glass substrate 1, there is a masking plate 1 for printing fluorescent materials of the present invention for filling and supplying fluorescent materials R, G, and B. The glass substrate 1 is After moving into a screen printing machine (not shown) provided with this mask plate 〇, use the cover -10- 200525575 (8) pulp plate S for printing and coating as ink. Conductor paste-like fluorescent materials r, g, B 〇

The mask plate 10 itself is a metal pattern opening 12 formed in the metal plate body 11 with coarse precision, and the photosensitive emulsion 13 formed by coating and solidified in the metal plate body Π is opened in the metal pattern. The inside 12 is provided with a filling pattern opening 14 having an opening area that is not larger than the filling filling groove portion 3 described above. This filling pattern opening 1 4 is used to fill and supply the conductor-like fluorescent materials R, G, and B in the filling accommodation groove portion 3 with a blade coating, and the corresponding filling materials are filled with fluorescent materials. Each of R, G, and B (R), green (G), and blue (B) is filled with each of the red (R), green (G), and blue (B) of the receiving groove portion 3.

In addition, the metal plate body 11 itself is formed of, for example, a flat metal (stainless steel) material having a meat thickness of 1000 to 150 μm, and a plurality of receiving groove portions arranged on the glass substrate 1 correspondingly are used. 3 full-area frame support is tightly drawn. The metal plate body 11 itself is not limited to the case where it is directly supported by the frame, and can also be made into a combined structure supported by the frame through the screen mesh. The openings of the metal pattern openings 12 which are arranged to form the pattern openings 14 are formed by using a metal mask plate, and can be used in the same way as the traditional pattern openings of the corresponding metal plate body 11 The metal pattern opening is formed by a process. In addition, the openings of the filling pattern openings 14 are formed as shown in FIG. 3, corresponding to most of the filling filling groove portions 3, and the opening area is larger than the filling filling groove portions -11-200525575. (9)

3 The metal pattern opening formed by the opening which is slightly larger. 2 After the metal plate body 11 is formed, a specific coating machine C is used to coat the photosensitive emulsion 1 3 and the metal pattern opening 1 2 is temporarily closed (emulsion coating process). After that, the filling pattern openings 14 formed with high accuracy are corresponding to the filling filling groove portion 3 as an image, and then exposed through the formed plate-making mask plate (filling pattern film) after exposure (plate-making pattern). Opening works). Through this process, the filling pattern openings 14 are solidified and left in the metallic pattern openings 12 and solidified by the photosensitive emulsion 13. In addition, the density ratio of the opening size between the metal pattern opening 1 2 and the filling pattern opening 1 4 is relative, which means that the opening size of the filling pattern opening 14 corresponds to the size of the filling receiving groove portion 3. The opening area may correspond to a pattern that is not larger than that; or it only means that the metal pattern opening 12 is sparse for the pattern, and only means that the two are relatively dense.

In addition, when the fluorescent materials R, G, and B are filled and supplied to each of the filled storage groove portions 3, fluorescent materials R (G, B) of any one color are used to correspond to the fluorescent materials R (G , B) The filling pattern opening 14 is formed at the position of the filling filling groove portion 3 which is filled, and the mask plate 10 of the filling pattern opening 14 is formed. The mask version 10 is itself closed. Next, on the blocking walls 2 on both sides of the closed filling storage groove portion 3, the spacer portion 2 set to a certain height is avoided to contact the opening surface of the closed filling storage groove portion 3 1 will be formed on the metal plate body 1 1 or the photosensitive emulsion 1 3 side. The spacer part 2 1 itself shown in the figure is formed on the entire surface of the metal plate body n, which has the photosensitive emulsion 1 3 coated and solidified to a certain thickness, and is made into a ratio of -12- 200525575 (10)

The thickness of the photosensitive emulsion 13 on the side of the opening surface of the closed filling storage groove portion 3 is slightly thicker, and the position corresponding to the closed filling storage groove portion 3 is not smaller than the opening area thereof. The remaining portion of the avoidance gap region 22 is formed in a protruding shape. In addition, this spacer portion 21 is not limited to the case where the respective filling and accommodating groove portions 3 adjacent to each other are formed, and may also be used to span two adjacent filling and accommodating groove portions. 3 to avoid the formation of the gap region 2 2. The protruding spacer portion 21 may be formed of a layered structure of two types of photosensitive emulsions having different hardness conditions during exposure.

Fig. 3 shows another embodiment. The symbols shown in this embodiment are the same as those of the embodiment shown in Figs. 1 and 2 and are given the same symbols. In other words, in this embodiment, the filling pattern openings 14 are almost the same in size as the metal pattern openings 12 formed in the metal plate body 11. In other words, the mask plate 10 in this embodiment is a metal pattern opening 12 formed in the metal plate body 11 with an opening formed in the metal plate body 11 to form a solidified photosensitive emulsion 13 is almost the same size as the metal pattern opening 12 and is provided with a filling pattern opening 14 formed by an opening having an opening area not larger than the opening area of the filling accommodating groove portion 3. When the metal pattern opening 12 and the filling pattern opening 14 are formed in the same size and shape, if the photosensitive emulsion 1 3 coated on the metal plate body Π is exposed, it means that the metal plate body 1 1 can be exposed. Used as a light mask version substitute, it can be opened to form a more precise filling pattern opening.4 In addition, it can reduce costs. -13- 200525575 (11) Next, the fluorescent material R (G, b) coated by the blade S is supplied to the filling storage groove portion 3 of each color, and the filling is not supplied and The infilled valley groove portion 3 of the other-colored fluorescent material G or B (R) enclosed by the metal plate body 11 is made of a spacer portion 21 made of a solidified photosensitive emulsion 1 3, and The avoidance gap region 22 maintains the non-contact state between the opening surface of the filled storage groove portion 3 and the three surfaces of the photosensitive emulsion. This spacer portion 21 and the method and configuration for avoiding the gap region 22 are the same as those described above, and are omitted here.

Next, an example of using the mask plate 10 will be described. After the screen printer (not shown) is installed, the glass substrate 1 on which the transport barrier wall 2 is formed as a workpiece is printed at the printing site, and the glass substrate 1 is exposed to the ON state below the mask plate j 〇. The positioned glass substrate 1 wipes the blade S to apply and print any one of the specific fluorescent materials R, 0, and b, which are inks, to the filling receiving groove portion 3 for filling and supplying. This screen printing process is repeated for each color, and the spacer portion 21 will abut the barrier wall 2 when the scraper S is rubbed, and only in the required filling and accommodating groove portion 3, The filling pattern openings 14 having an opening area not larger than the filling storage groove portion 3 are sufficient to supply a sufficient amount of the predetermined fluorescent materials R, G, and B together with the solvent to the filling storage groove portion 3 separately. Further, since the filling receiving groove portion 3 'having a fine width of about 50 / m can be filled, the depth can also be about 5 to 2 times that of the depth. When the fluorescent materials R, G, and B are filled with the filler, since the conductive paste-like fluorescent materials R, G, and B contain a solvent, even if the fluorescent materials R, G, and B are filled with the filler, the spacer portion 21 may overflow. 2. Avoiding the gap area 2 2 will use metal-14- 200525575 (12) The plate body 1 1 itself closes the filling and accommodating groove portion 3 and does not cause fluorescent materials r, 〇 to be attached around the opening of the filling and accommodating groove portion 3. , B. In addition, in FIG. 1 and FIG. 2, in each of the three-color filling storage groove portions 3, the blue (B) fluorescent material B is filled and supplied, and the scraper is instructed to be used. The plate S is coated with a fluorescent material R for red (R) through the mask plate 10, and a mask plate 10 corresponding to the fluorescent materials R, G, and B of each color is prepared in advance to supply the fluorescent material. The light materials R, G, and B enter the filling and accommodating groove portion 3.

Then, by successively applying the printing materials S, R, G, and B of the three colors of fluorescent materials R, G, and B into the filling and accommodating groove portion 3 by sequentially applying coating and printing, it is dried once, in a conventional manner. The difference is that it is not necessary to go through the drying process after the supply and filling of each color. Only one drying process can cure the fluorescent materials R, G, and B.

In addition, even if the filling pattern opening 14 formed by the photosensitive emulsion i 3 is damaged due to repeated application, etc., as long as the portion of the photosensitive emulsion] 3 is peeled off, the emulsion coating process and the plate-making pattern opening process are performed. The filling pattern opening 14 may be formed again, and the metal plate body 11 itself may be used repeatedly. 4 to 6 show another embodiment. In the fourth figure, 'the case where the filling groove 3 of the honeycomb structure serving as the plasma display device is filled with the fluorescent materials R, g, and B is classified by the corresponding lengthwise separation. The partition sheet portion 15 partitioned by the partition wall 5 of the filling accommodating groove portion 3 is provided in the filling pattern opening 14. When the fluorescent materials R, G, and B are supplied, the partition plate portion 15 is fitted to the partition wall 5 correspondingly, and then the mask plate S is wiped with a scraper -15- 200525575 (13) The mask plate S is wiped.

FIG. 5 shows a case where the fluorescent material R, G, and B are supplied to the charging receiving groove portion 3 as a stripe structure of the plasma display device, along the longitudinal direction of the charging receiving groove portion 3 In addition, a long filling pattern opening 14 formed in correspondence with the filling pattern openings 14 is provided at a proper interval to connect the two edge sides of the filling pattern opening 14 at both edge sides. In this case, the partition piece portion 15 should be made as small as possible along the length direction of the filling pattern opening 14, and it is considered that the partition piece portion 15 cannot affect the filling groove. Charging of fluorescent materials R, G, and B in the groove portion 3.

In FIG. 6, the same as in FIG. 5, the filling pattern opening 14 is provided with a partition piece portion 15 that closes a part of the filling pattern opening 14, and the partition piece portion 15 is based on using or not. The opening portion of the filling pattern opening 14 in which the partition sheet portion 15 is provided is provided so that the mask plate 1 for fluorescent material printing is not formed relatively long. In this case, when the specific fluorescent materials R, g, and B are supplied to each of the charging storage groove portions 3 of the plasma display device by screen printing using the doctor blade S, the charging is performed along the charging surface. In the rectangular direction of the accommodating groove portion 3, the mask plate 10 is moved slightly to fill the supply. The range of the movement is made by moving the partition portion 15 before the movement to cover the fluorescent materials R, G, and B. Fill the position of the partition portion 15 of the unfilled area in the filling accommodation groove portion 3 (see (a), (b) of FIG. 6). In this way, the masking plate portion 15 can be used to maintain the opening width of the filling pattern opening M to increase the mask plate]. At the same time, after the micro-movement, the non-charging groove portion 3 before the micro-movement can be sequentially filled. The inside of -16-200525575 (14) is filled with the fluorescent materials R, G, and B to fill the unfilled area of the containment groove portion 3. In addition, the partition wall 5 itself is equipped with a forming element of a metal plate body 11 having a slender inner core structure within a narrow width, compared with a forming structure composed of only a cured photosensitive emulsion 13 Then, a sufficiently strong element can be obtained.

[Effect of the invention]

As described above, according to the structured invention of the present invention, the metal pattern opening 12 formed in the opening of the metal plate body U is formed by using the opening forming element made of a photosensitive exposure material to form a more precise filling pattern opening 1 4 which is more solidified. Therefore, it is possible to fill and supply predetermined fluorescent materials R, G, and B in the very fine filling and accommodating groove portion 3, and then use screen printing to form a high-precision pattern required for a plasma display device. For example, the width between the barrier ribs 2 is 50 / m. Furthermore, for example, even if it is 30 to 35 #m, the fluorescent materials R, G, and B of each color of the conductor paste can be filled. Into the filling and accommodating groove portion 3. Next, the solidified photosensitive emulsion 1 3, which belongs to the opening forming element, can be repeatedly peeled and regenerated, which is beneficial to reducing the running cost. For the unique penetration of the metal plate, it can also be managed and used in the same way as the gel mask plate. Maintenance is also very simple. In addition, since the filling pattern openings 14 are free of sieve holes, the opening area does not expand and contract even if the blade is coated, and the filling can be supplied to the filling storage groove portion 3 with a stable discharge amount. -17- 200525575 (15) For example, for the filling receiving groove portion 3 with a width of 3 0 // m, a depth of 20 " m, and then a width of 60 // m, a depth of 100 ^ / m, or It is a width l0〇 " m, depth 2 0 0 // m and other sizes of the filling and accommodating groove portion 3, the fluorescent material r, 〇, B has a small amount of change in the filling amount, and can be manufactured without The stable quality of the bad effects caused by the traditional sieve. Further, it is possible to adjust the filling amount of the filling storage groove portion 3 of the fluorescent materials R, G, and B according to the size of the filling pattern openings 14, so that the filling can be applied more precisely.

Moreover, the spacer portion 21 can maintain the non-contact state between the metal plate body 11 and the opening surface of the filling and accommodating groove portion 3 by using the avoidance gap region 22 formed between the spacer portion 21 and the conventional one. Filled and hardened red (R) fluorescent materials, filled and hardened green (G) fluorescent materials, filled and hardened blue (B) fluorescent materials, and then the firing process must be repeated for each color. As long as the red (R) fluorescent material, the green (G) fluorescent material, and the blue (B) fluorescent material are successively printed and coated, the colors can be hardened and fired at one time. Get a further simplification of the process engineering. In this way, in the non-contact space formed by avoiding the gap area 22, in addition to preventing R, G, and B from adhering to continuous printing, it can be heat-treated at one time, so it does not require too many drying furnaces, and it can release the workpiece. Thermal stress can also save electricity costs. In addition, the opening of the filling pattern opening 14 is formed to be almost the same size as the metal pattern opening 12, so that the opening of the metal pattern opening 12 corresponding to the metal plate body 11 can be similarly formed, which can further reduce the cost. In addition, the mask plate for fluorescent material printing 10 is moved slightly in the length direction of the filling receiving groove portion 3 to fill the fluorescent material R, G, and B to the filling receiving groove -18- 200525575 (16) groove portion Because of the inside of 3, even if there is a partition portion 15 in the filling pattern opening 14, the fluorescent materials R, G, and B along the filling storage groove portion 3 that is continuously extended can be continuously filled and supplied. In addition, the partition sheet portion 15 itself is intermittently arranged in the rectangular direction of the filling pattern opening M, so that the opening width of the filling pattern opening 14 can be maintained from time to time, so that filling can be provided for this high-precision method. The resulting fluorescent materials R, G, B.
