In order to integrate the metal bond into various patterns and the color filter of the liquid crystal display, a variety of pattern forming methods have been developed, for example, screen printing (Screen printing) Scheme) or Photolithography scheme. However, according to the screen printing method, the precision of the pattern may be lowered. In addition, according to the photolithography method, its complicated necessary processes include: deposition of photoresist, exposure and development, and the existence of the process limit 201242777 in the formation of the fine_. In order to solve the above problems, a gravure printing scheme has been developed which uses a transfer roller to print a pattern onto a substrate. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic illustration of a prior art gravure printing process. According to the gravure printing method, the printing material 50 can be supplied onto a pattern roll 1 by using a knives 40, and the surface of the pattern roll 10 has an engraved pattern for filling the material 50 for the word P. The pattern roll 1〇 can be filled into the J-slot pattern by using a knife 4〇. As shown in Fig. j, the knives include a blade that occupies a surface of the blade and the knife 40 contacts the surface of the pattern roll. Thereafter, the pattern formed on the pattern roll 1〇 is transferred to a rolling roll (including a blanket rQ11) such as rubber. The -_21 transferred to the rotating roller 2G can be printed on the substrate 3'. However, 'the method of filling the printed material 50 through the blade 40' is a certain number ^^ 5 〇 ^ ^ (horizontal direction b). With the cocoon 11 has the level as described above /. The internal movement of the pattern in the vertical direction a, then, 201242777 moves to the horizontal direction b of the pattern, and the pattern is filled with the fill material. When the scraper:,: 70, the action of the printed material is in the middle of the blade 40 and the tie roller are in line contact with each other, because the _ 圚 圚 tea roll ^ often,,, Tian Wei line width, wait until the printed material is filled The pattern portion of the horizontal direction b, otherwise the helmet can be produced. The present invention provides a method for light patterning, a method for patterning a pattern roll to form a pattern, and an ability to include a simple axis-, red __ degree. a method of forming a pattern to print a predetermined pattern, the eight steps including: preparing - the roll '_ case roll has a groove pattern capable of accommodating a county (p_), the groove pattern of the pattern roll is borrowed It is formed by tilting the preset pattern - an acute angle, and then 'by the _ roller to transfer the job onto the substrate. The monthly embodiment provides a pattern roll comprising: a groove pattern for accommodating the glue, the groove comprising the first pattern portion and the second pattern portion, the first pattern portion and the The second _ partial wing (with s), the first portion is in a light circumferential direction with the pattern (circumferential price as (4) is inclined, and the second pattern portion is in the longitudinal direction of the figure _ (10) gitudinaldi (10) There is also an oblique relationship. The embodiment of the present invention provides a printing device that includes the above-described pattern roll. 201242777 As described above, the pattern roll, the method of forming the pattern using the pattern roll, and the like The printing device of the pattern roll does not include a __ share in parallel with the longitudinal direction of the pattern roll, so that a certain amount of Na can be filled in the groove pattern, so a predetermined pattern can be accurately [Embodiment] In the description of the embodiments, it should be understood that when a layer (or film), a region, a pattern, or a structure is mentioned in another substrate, another layer (or film), Another area, another weld (4)) or another - map Under ', /', 'when it can be, directly, or,, indirectly, on other substrates, layers (or films), regions, pads or patterns; or, one or more The position of the intervening layer will be referred to in the drawings. In the drawings, the thickness or size of each layer is exaggerated, omitted or schematically depicted, which is convenient for each element of the θ α and ' ® style towel. The dimensions are not all true dimensions. In the following, the embodiments will be described in detail with reference to the drawings. In the following, the description will be made with reference to the pattern base method using the pattern and a printing device including the pattern roller. 3 to 7 are to be described in detail. Fig. 3 is a flow chart showing a pattern forming method according to an embodiment. Fig. 4 is a diagram showing a flat pattern formed on a second substrate. Fig. 5 shows an embodiment according to an embodiment. FIG. 6 is a perspective view of a printing apparatus, and the printing apparatus package 201242777 includes a pattern roll and a pattern forming method according to an embodiment. FIG. 7 is a plan view showing a step of forming a final substrate. Please refer to Figure 3, The pattern forming method in the embodiment includes the steps of preparing a pattern roll (step ST10), transferring a paste onto a substrate 32 (step ST20), forming a final substrate 32 (step ST30). Step ST10 prepares a pattern roll for detailed description. According to an embodiment of the present invention, in order to form a predetermined pattern 11 as shown in FIG. 4, gravure printing can be performed by a pattern roll 100 as shown in FIGS. 5 and 6. A groove pattern 112 is formed in the surface of the pattern roll 100. As shown in Fig. 5, the groove pattern H2 is formed in the pattern light 1 scarf, and corresponds to a predetermined pattern of the Γ7 brushed on the final substrate 32. 114a is shown in Fig. 4. The groove pattern 112 is formed by tilting the preset_1143 to a predetermined angle Θ. The predetermined angle θ is changeable according to the 1_ shape. For example, the county corner preferably includes an acute angle because a pattern parallel to the longitudinal direction X of the pattern view 100 will not be formed. z stomach angle Θ | | a circumference can be between 丨. To 45. between. If the predetermined angle 0 is smaller than the longitudinal direction 嶋 of the 嶋 level, the efficiency of a Μ and 图案 pattern may be lowered. In addition, if the silent angle 0 is greater than 45. When a 3! needs to be cut to form the final substrate 32 (as shown in Fig. *), a large amount of soil will be destroyed as shown in Fig. 6. Therefore, its manufacturing costs will rise. 8 201242777 A glue 50 (shown in Figure 6) is a print filled in the grooved drawing. In the printing process, it can be combined with one = Fig. 4, _ 亀 亀 — — — 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 第一 且 且 且 且 且 且 且 且 且Lifting the first part, P1 is parallel to a left or right edge of 32. The second portion p2 is parallel to a top or bottom edge 32b of the final substrate. Therefore, if the _114_ case_ is not inclined at an angle of 0, there will be a partial pattern parallel to the longitudinal direction X of the pattern roll (10). However, according to the present embodiment, the pattern 114a is inclined with an angle Θ which can increase the time for filling the glue 50 and can ensure the fluidity of the glue in the printing process. Therefore, the filling efficiency of the dope 50 can be increased. In order to print the preset pattern 114a, the -the pattern portion pi〇 and the circumferential direction Y of the pattern are in a slit relationship. The portion of the P2G and the longitudinal direction X of the pattern 1 are inclined. The first pattern portion P10 is a first portion P1 for printing the preset pattern 114a, and the first pattern portion P10 is inclined by a predetermined angle Θ with the circumferential direction Y of the pattern roller 100. The range of the pre-angle Θ can range from Γ to 45. between. Similarly, the second pattern portion P2 疋 is used to print the second portion P2 of the preset pattern 114a, and the second pattern portion p2 倾斜 is inclined by a predetermined angle < 9 with the longitudinal direction X of the pattern 辕100. The predetermined angle θ may range from one. To 45. between. 201242777 As described above, even when the -first pattern portion a is perpendicular to a second pattern portion b, a portion which is parallel to the longitudinal direction of the _roller is not formed. However, since this embodiment is not limited thereto, the first pattern portion P1() and the second pattern portion p2〇 may form various angles with each other. The step of transferring to the substrate (ST20) will be described in detail below. Referring to FIG. 6, the doctor blade 40 is in contact with the groove pattern (1) of the pattern parent to fill the groove _ 112, which is used as a printing material. The knife 40 can include a blade 42 and a grip 41 that supports the blade 42. When the glue 50 is filled into the groove pattern 112, the blade 4 is moved to come into contact with the pattern roll 1〇〇. After that, the pattern roll 100 can transfer the dope 21 to the rotating roll 2〇. For example, the rotating roller 20 is in the shape of a 'shape' so that the rotating roller 2 is rotated. A blanket comprising rubber wound around the outer circumferential surface of the rotating parent. Next, the rotating roller 20 is rotated on the substrate 31 to transfer the dope 21 onto the substrate 31. Hereinafter, the step of forming the final substrate (ST3〇) will be described in detail. Referring to FIG. 7, a final pattern 114a is formed on the substrate 31 having a predetermined angle 0 between the final pattern and the substrate 31. In detail, the final pattern (10) may be inclined at an angle to the substrate 31. This angle is larger than the angle between the facet 112 formed on the pattern _100 and the pattern roll. Therefore, in order to obtain the preset pattern 丨..., the substrate 31 can be cut at an angle Θ. In other words, in order to form the final substrate 32, the substrate 31 201242777 is cut in a manner such that the edge of the substrate 31 and the edge of the final substrate & Thus, the final substrate 32 having the preset pattern face as shown in Fig. 4 is obtained. Therefore, even if a portion of the predetermined pattern 114a is parallel to the longitudinal direction of the pattern pro X, the groove pattern 112 can be formed at a predetermined angle 0 to be formed on the pattern roll, so the filling efficiency of the glue 50 can be increased. Since the precision of the pattern is improved, a high-quality printing result can be obtained. Therefore, a satisfactory pattern can be obtained even without changing the preset pattern (10).
