INSTRUCTION DESCRIPTION OF THE INVENTION (1) BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing light, earth, and 诂田α $ & α ^ ^ αι , Hanliang's viewing device, and more specifically, related to the setting of the gray clothing, the eye & gy, the middle twist conversion phenomenon is removed to improve the viewing angle and display quality In order to compensate for the film of Fuwang, and its manufacturing method 'the lighting method using this film, (the display device of the viewing angle. 2. The related art description - the general display device is used as a medium through which the user can The data is processed by the data processing unit to understand the formation of data. The display device is divided into a digital display device and an analog display device according to the driving method. The LCD (liquid crystal display) is a typical digital display device. This (4) has a large-size screen, High resolution, small size and weight, etc. At the same time, the CRT (cathode ray tube) type display device is typically an analog display device. The display device has the advantages of being able to easily realize a large-size screen and high resolution at low cost. However, (the 11-inch type display device has a disadvantage of being larger in size and heavier than an LCD having the same screen size. Therefore, the LCD It has been continuously developed. Recently, lCD has been widely used to replace CRT type display devices. Recently, the research on 1(:1) has focused on the technological development or improvement of the driving method and its structural improvement. Therefore, LCD has been 1307421 A7. ------- BZ___ V. INSTRUCTIONS (2) --- The current display quality and its subsequent improvement in the driving method. Furthermore, the LCD can be reduced in size and weight by its structural improvement. Alas, despite the rapid development of LCD technology, LCD still has many problems, especially its driving method and structure. These problems are described in the case of TN (Twisted Nematic) LCD. These problems are grayscale conversion phenomena. The conversion phenomenon means that the gradation is converted in the image. Generally, in the LCD, the higher the driving signal strength, the higher the brightness. However, even if the driving signal has a large intensity, it has a special part of the LCD. The brightness is relatively low. This phenomenon, which often occurs in LCDs, is called the gray-scale conversion phenomenon. Typically, the gray-scale conversion phenomenon is a hindrance factor for achieving high display quality. Furthermore, the gradation conversion phenomenon reduces the brightness. The angle of view has a bad influence, and the contrast ratio is defined as 1〇:丨 or more. Therefore, the angle of view is narrowed. The fact that the angle of view narrows means that the angle formed between the user's eyes and the LCD surface is only slightly changed. It will have a part in which the user cannot recognize the information content displayed on the LCD. This is also a hindrance factor for achieving high display quality. In summary, the 'gradation conversion phenomenon does not substantially affect the LCD display operation'. The viewing angle is narrowed, and thus the LCD display quality is substantially deteriorated. Recently, in order to solve the problem of reduced viewing angle due to the phenomenon of gray scale conversion, a film for compensating for light characteristics has been provided. However, this compensation film effectively improves the viewing angle to a certain extent, but it does not solve the problem of the gradation conversion phenomenon, which is a basic factor. This paper scale applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ··>111·—IV· _, 1§1丨

Fig. 1 shows a specific example of a film 2 for compensating for optical quality. Referring to Figure 1, reference numeral 31 identifies the substrate. According to the present invention, the substrate 310 transmits light 'and the optical quality of the light is changed when the light is transmitted. Here, the optical property change also includes the fact that the substrate 31 has a light polarization work. The film 200 of optical characteristics is placed on the surface of the substrate 31. Thereafter, the film 2 for compensating for optical quality is referred to as "the size of the paper used to supplement the National Standard (CNS) A4 specification ( 21〇><297 public interest" 1307421 V. INSTRUCTION DESCRIPTION (7) Thin film of 〇 characteristics, preferably, film 200 for compensating for light characteristics is made of transparent film 217 and second transparent film 210 Composition - As an example, the first transparent film 217 is used to fix the second through 210 to the substrate 31 and change the optical path. Specifically, in order to fix the first transparent film 217 to the second transparent film 21 and change the light path, a concave portion (four) having a predetermined shape is formed on the surface of the first transparent film 217. At this time, the recess 217a may have various shapes. For example, the recess 21 may be a groove having a V-shaped wheel and arranged in series in a row. In other cases, the recess 217 & may have a triangular pyramid shape, a quadrangular pyramid shape, a pentagonal pyramid shape, a polygonal pyramid shape or a conical shape. The second transparent film 210 is partially coupled to the upper surface of the first transparent film 217 having the concave portion 21. At this time, the first transparent film 21 has a convex portion 216 corresponding to the concave portion 2A, so that the convex portion 216 is engaged with the concave portion. For example, in the case where the concave portion 217a is a v-shaped groove in which the long strips are continuously arranged in an in-line (as shown in Fig. 1), the convex portion 216 of the second transparent film 21 has a bifurcated columnar shape, Corresponding to the v_shaped contour of the recess 2丨7& as shown in Fig. 2. As described above, the first transparent film 217 has a recess 217 & which has a desired contour or structure. The convex portion 216 of the second transparent film 21 has a desired shape corresponding to the contour or structure of the concave portion 217a. Thereafter, the optical and physical properties of the first and second transparent films 217, 21 will be described in more detail. The first transparent film 217 of the film 2 for compensating for optical characteristics has the first paper size applicable to the China National Standard (CNS) A4 specification (210 X 297 public love)

In this case, the first refractive index system and the substantially "secondary refractive index are the same." When the field light passes through the portion where the first transparent film 217 overlaps the second transparent film 210, the change is made... The angular change is within the predetermined dry circumference. At this time, the values of the first and first refractive indices of 笫-"silver_β and the first transparent films 217 and 210 are not important. It is important that the difference between the first and second refractive indices is more important. According to a specific embodiment of the present invention, it is preferred that the difference between the first and second refractive indices is 0.1 or less. The most desirable difference is 〇. It is also important to overlap the concave portion 217a formed on the first transparent film 217 and the convex portion 216 of the second transparent/film 210 or the convex portion of the fourth portion. This is due to the grayscale conversion phenomenon and the visual (4) being improved or deteriorated depending on the depth of overlap. Therefore, sometimes the depth of overlap between the convex portion 216 and the concave portion 217a needs to be controlled. According to an embodiment of the present invention, the first transparent film 217 is composed of a material having flowability and adhesion, and then the first transparent film 217 is combined with the first transparent film 210, such that the first transparent film 217 and the first transparent film The convex portions 2 of the two transparent films 210 are overlapped. In particular, the first transparent film 217 is composed of a fluid material having an unshaped shape. More specifically, this fluid material has adhesiveness and a first refractive index. The transparent gel (which cures depending on the passage of time, i.e., can be cured depending on conditions) can be used as the first transparent film 217. In another embodiment of the present invention, the first transparent film 217 has a flowable paper size applicable to the Chinese National Standard (QJS) A4 specification (21〇χ297 public) 1307421. 5. Description of the invention (, dynamic and first refraction) The UV (ultraviolet) curing agent (or hardener) which is cured under special conditions (for example, exposed to ultraviolet light) can be used as the first transparent film 217. Meanwhile, the second transparent film 21 can be rigid and solid. At this time, the contour form of the convex portion 216 formed on the second transparent film 210 is not heavy, and the cross-sectional area of the convex portion is gradually increased to the second transparent film 210. '' In the example, the convex portion 216 of the second transparent film 210 has a prismatic shape. Therefore, as shown in the second figure, the convex portion 216 of the second transparent thin 210 has two inclined faces 212 and 214. In this specific example, One of the two inclined faces is defined as a first inclined point 212. The other side of the one side that is in contact with the first inclined surface 212 is defined as a second inclined surface 214. Here, the specific angle is at the first inclined surface 212 and Formed between water levels, and in the second The inclined surface 214 is formed between the inclined surface 214 and the horizontal plane. As shown in Fig. 1, the angle between the α-th inclined surface 212 and the horizontal plane, and (4) the angle between the second inclined surface 214 and the horizontal plane. The relationship between the angle β and the /3 angle is ( α+/3)<18〇.. Each of the alpha angle and the no angle is between about 10. and 90. The privateness of the benefit i, the angles α and /3 can be the same for each other. Or the difference between the right and left viewing angles and the upper and lower viewing angles is based on the ^ angle and the cold angle. Therefore, when designing the LCD, the corners and cold corners are carefully considered to obtain the desired angle of view. At the same time, the second transparent film 210 is changed. For example, the film surface as shown in Fig. 3 is applied to the Chinese National Standard (CNS) Α4 specification (210×297 mm).

Therefore, the light is smoothly and continuously advanced, so that a light distribution with a stepped distribution can be avoided. Meanwhile, Fig. 4 shows another specific example of the second transparent film 2丨〇. The convex portion 218 of the first transparent film 210 is projected on the second transparent film 21 to protrude in the form of a dot. Of course, the cross-sectional area of the convex portion 218 is gradually increased to the second transparent film 210. As shown in Fig. 4, the convex portion 218 protruding at a desired height may have a polygonal pyramid shape having at least three or more sides. Preferably, in one embodiment, the protrusion 218 can have a conical shape (which can have several sides). When the convex portion 2丨8 has a conical shape, as shown in Fig. 4, the viewing angle is improved by more than 36 〇. angle. Furthermore, the 'gradation conversion phenomenon is suppressed. The first and second transparent films 217 and 21 are provided to the substrate 31 to perform the desired function. Thereafter, a method of bonding the first and second transparent films 217, 21A will be described in more detail. The first transparent film 217 formed on the substrate 310 with reference to the first substrate is formed to have a desired thickness. As shown in Figs. 2 to 4, one of the second transparent films 2 ι is superposed on the first transparent film 217. As a preferred embodiment, the second transparent film 210 shown in Fig. 2 is attached to the first transparent thin film 217. At this time, the entire convex portion 216 of the first transparent 4 film 210 is not completely overlapped with the first transparent film 2 i 7 . The reason why the entire convex portion 216 of the second transparent film 210 is not completely coupled to the first transparent film 217 is as described above, and the structure solves the viewing angle and the gradation conversion (please read the back note on the front page), tT·4 ,
1307421 A7 11 五、發明説明 現象之問題。 此時’插入透明薄膜210内之凸部216之深度非常重要。 A 士第1圖所不’當凸部216之整個高度被定義成H,當 卜凸。卩之凸J部份偶合至第一透明薄膜之凹部時第二透 明薄膜凸部未偶合至第一透明薄膜之部份之高度係定義成1307421 A7 11 V. INSTRUCTIONS Description of the phenomenon. At this time, the depth of the convex portion 216 inserted into the transparent film 210 is very important. The first height of the convex portion 216 is defined as H, and is convex. The height at which the second transparent film convex portion is not coupled to the first transparent film when the convex J portion is coupled to the concave portion of the first transparent film is defined as

The ratio L of the convex portion 216 inserted into the first transparent film 210 is as follows: Equation 1 L = h / H; In Equation 1, the entire same degree of the convex portion 216 of the first transparent thin 臈 21 假 is sighed 1 And the degree of return _ 〇 4, the ratio L of the convex portion 216 inserted into the first transparent film is 0.4/1, that is, 〇.4. In other words, this means that 60% of the height of the convex portion 216 is inserted into the first transparent film. Thereafter, the influence of the ratio of the convex portion 216 of the second transparent film 21 into the first transparent film 210 on the light path will be described. Referring to the 11th, the portion of the light radiated from the substrate 31G passes through the overlapping projections of the second transparent film 210 (which are inserted into the first transparent film 217). In this region, the light system is refracted at a minimized angle because the refractive index of the first transparent film 217 is substantially the same as that of the second transparent film 21. Thereafter, the light is defined as linear light 515i. At the same time, the remaining portion of the light radiated from the substrate 310 is incident into the air (which is a medium different from the first transparent film 217) via the first transparent film 217. Then, the light continues to move and reaches the convex surface of the second transparent film 21 which is not inserted into the first transparent film 2', and then enters the first transparent thin film 217. This paper scale applies to China National Standard (CNS) A4 specification (210X297 mm) 1307421 A7 ___B7 V. Invention description (12) (Please read the note on the back} Write this page) Then '羌线5 1 5h and 5 15j The light path is completely changed by the difference in refractive index between the air and the second transparent film, and the light is incident on the convex portion 216 of the second transparent film 210. Thereafter, the light whose light path is changed is defined as the first refracted light 515h and the second refracted light 515j. At this time, the linear light 515i and the first and second refracted lights 515 [1 and 51] are inversely proportional to each other. For example, if the ratio of the convex portion 216 inserted into the first transparent film 21 is [minimized, the light content of the linear light 515i is increased, but the light content of the first refracted light 515h and the second refracted light 5 1 5 j is reduced. In this case, the viewing angle is narrowed and a gradation conversion phenomenon may occur. Therefore, according to a specific example of the present invention, the ratio l of the convex portion 2丨6 inserted into the first transparent film 210 needs to be at least 〇 5 or more. Meanwhile, if the ratio l of the convex portion 216 inserted into the first transparent film 2 is maximized, the light content of the linear light 515i is the smallest. Then, the amounts of the first and second refracting lights 515h, 515j are the largest. In this case, the viewing angle in the front portion is largely reduced, thereby deteriorating the display characteristics of the front view. Therefore, according to another embodiment of the present invention, the ratio l of the convex portion 216 to be inserted into the first transparent film 210 needs to be at least 〇7 or less. Therefore, the ratio of the convex portion 216 inserted into the first transparent film 21 is appropriately controlled to the extent of 0.05 to 0.7 in accordance with design conditions. Thereafter, a method of fabricating a film 2 (which has the structure and characteristics as described above) for compensating for optical characteristics will be described with reference to Figures 5 to 7. Referring to Fig. 5, on the upper surface of the substrate 31, it forms a first transparent film of the uniform thickness of the film 2', which has a first refractive index and fluidity, and it has a specification. (2) 0Χ297 public Chu]- ------- 1307421 A7 B7 V. INSTRUCTIONS (13) It consists of a transparent adhesive or a UV curing agent (or hardener). Then, as shown in Figure 6, as shown in Figures 1 to 4. The second transparent film 210 having the convex portion 216 is arranged in line with the upper surface of the first transparent film 217 and stacked thereon. In the case where the first and second transparent films 217, 210 are simply stacked, the first addition The pressing roller 810 is placed on the side of the upper surface of the second transparent film 21A to generate a predetermined pressure on the second transparent film 21A. In other cases, the second pressing roller 82 and the first pressing roller 81 The lanthanum is provided on both the substrate 310 and the second transparent film 21 , to simultaneously press the second transparent film 21 〇 and the substrate 31 以 at a desired pressure PI, P2. At this time, the first and second additions The pressure applied by the rollers 810, 820 is appropriately controlled because the ratio of the projections 216 inserted into the first transparent film 2 is borrowed. The pressure is applied to the first and second transparent films 217, 21〇. Thereafter, as shown in Fig. 7, the first transparent film 217 is cured, and the first and second pressure rollers 81 are 〇, 820 accurate. The first and second transparent films 217, 210 are pressurized. According to the present invention, there are provided two methods of curing the first transparent film 217. In the first specific example, as shown in Fig. 7, the ultraviolet system is along the first - a younger pressurizing roller 81 〇, 82 〇 precisely presses the path scan of the first and second transparent films 217, 210. According to the first specific example, the second transparent film 21 is placed on the first transparent film 217 When curing, the positional change of the second transparent film 21〇 is minimized.

INSTRUCTION DESCRIPTION (Η) After pressing the entire surface area of the first and second transparent films 217, 2 10 , the ultraviolet rays are scanned over the entire surface area of the first transparent film 217 to cure the first transparent film 217. The film 200 suitably prepared by the above-described method for compensating for light characteristics can be applied to any kind of display device having a desired structure, the objective of which is to avoid gradation conversion phenomenon and increase viewing angle. Thereafter, a display device to which the film 200 for compensating for light characteristics is applied and a lighting method for the display device will be described. Figures 8 and 9 show a display device 800 having a film 200 therebetween for compensating for optical properties. Referring to Fig. 8, in accordance with an embodiment of the present invention, display device 800 is a liquid crystal display device (LCD) that precisely controls liquid crystals and displays information. Thereafter, reference numeral 800 also refers to an LCD. The LCD 800 is composed of a film 200 for compensating for optical characteristics, an LCD panel assembly 300, and a rear light assembly 700. The LCD 800 rear optical component 700 is used to perform the display operation, such that the LCD 800 can display an image without an external light source. Therefore, the backlight assembly 700 does not use an external light source to perform the basic components of the LCD for display operation. Referring to Figures 8 and 9, the LCD panel assembly 300 of the LCD 800 is comprised of an LCD panel 360 and a kinetic module 370. The LCD panel 360 has a TFT substrate 340, a color filter substrate 320, a liquid crystal 330, a first polarizing plate 350, and a second polarizing plate 310. More specifically, the TFT substrate 340 is controlled to be applied to each area (which is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) from the paper scale. 17 (Please read the back note before writing this page) Writer, ^· .11- 1307421 A7 B7 V. Description of invention (15) Dynamic strength of one of several small surface areas divided by surface area. The color filter substrate 320, which is relative to the TFT substrate 340, supplies reference power. The first polarizing plate 350 is formed on the bottom surface of the TFT substrate 340, and the liquid crystal 330 is injected between the TFT substrate 340 and the color filter substrate 320. The second polarizing plate 310 is formed on the upper surface of the color filter substrate 320. Reference numeral 325 refers to a common electrode. At the same time, the illuminating module 370 of Fig. 9 is connected to the TFT substrate 340, and the stimuli signal is applied to the TFT substrate 340. However, the L C D panel assembly 300 cannot perform the display operation on the side where the light content is not sufficiently supplied. This is caused by the characteristics of the liquid crystal 330 which is a constituent element of the LCD 800 because the liquid crystal 330 controls the transmittance of light, but does not generate light. Therefore, the backlight assembly 700 is placed on the LCD panel assembly 300 in accordance with the characteristics of the liquid crystal 330. Back light assembly 700 converts light generated from a line source or point source into a surface source having a planar light distribution (i.e., a uniform distribution of brightness). Therefore, the rear light assembly 700 is composed of the lamp assembly 520, the light guide plate 530, the optical sheet group 400, the light reflecting plate 600, and the receiving container 650, as shown in FIG. More specifically, the luminaire assembly 520 is comprised of a luminaire 5 15 and a shade 5 10 . At this point, the luminaire 515 produces light in all directions. The shade 510 covers the luminaire 515 and reflects the generated light in the desired direction. A light guide plate 530 having a rectangular parallelepiped shape is coupled to the luminaire assembly 520. The light guide plate 530 causes the light generated from the lamp assembly 520 to have a surface light source distribution and also to change the direction of the light. At the same time, the light output from the light guide plate 530 has a surface light source distribution, but the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210×297 mm) 18 (Please read the back note to write this page) it,, •, V5. -^- 1307421 A7 ____B7 V. Description of invention (16) The uniformity of brightness of light is low. Therefore, a diffusion plate 420 for diffusing light is placed on the upper surface of the light guide plate 53A. A three-dimensional sheet 410 for compensating for the direction of the diffused light is placed on the upper surface of the diffusion plate 420. On the surface of the second polarizing plate 310, when one of the LCD panel assemblies 300 is coupled to the backlight assembly 7 as described above, it provides a film 200' for compensating for optical characteristics to avoid the LCD panel assembly 300. The gradation conversion phenomenon of the light displayed on the screen is also greatly improved. A lighting method from the rear light assembly 700 to the LCD panel assembly 300 and the film 200 for compensating for optical characteristics will be described with reference to Fig. 10 or 11. Referring to Fig. 10, the light generated from the luminaire assembly 520 is intruded into the light guide plate 530 and changed into a surface light source distribution. Thereafter, the light output from the light guide plate 53 is defined as the first light ray 515a. At this time, since the first light ray 515a has a very uneven brightness distribution, after being incident on the diffusion plate 420, the first light ray 515a is diffused and converted into a second light ray 515c having a uniform-brightness distribution. Reference numeral 515b refers to light reflected by the reflecting plate. The second light ray 515c has a uniform brightness distribution compared to the first light ray 515a. However, in the light conversion method of converting light into a uniform luminance distribution, the light content of the first light ray 5 15 guided to the LCD panel 360 is lowered, and therefore, the luminance is also lowered. In order to avoid a decrease in brightness, the second light ray 5 is almost guided to the LCD panel 360 through the three-ply sheet 41 formed on the upper surface of the diffusion plate 420. Thereafter, the light whose direction is compensated by the three-ply sheet 41 被 is defined as the third ray 515d. Then, the third light 515 with sufficient measurement and brightness uniformity is entered into the paper scale (Caizhou Standard (CNS) A4 specification (2) 0X297 mm) 19 (Please read the back note first to write this page) 4 1307421 A7 _____B7_ V. Description of the invention (17) Projected into the LCD panel 360. The third light has an s wave and a P wave. In a specific example, the first polarizing plate 350 of the LCD panel 360 filters the S wave. Therefore, only the P wave passes through the first polarizing plate 350. The light rays that are composed of the first polarizing plate 350 and composed only of the P waves are defined as the fourth light rays 515e. The fourth light ray 515e passes through the liquid crystal 330 between the TFT substrate 340 and the color filter substrate 320. Therefore, the transmittance of the fourth light is changed. The fourth ray 515e passes through the RGB pixels of the color filter substrate 320 to be filtered. The filtered light is defined as the fifth ray 515f. Thereafter, the fifth light ray 515f is converted into the sixth light ray 515g by the second polarizing plate 31. If the sixth light 5 5 5 g is incident on the user's eyes, the user can clearly recognize an image. Thereafter, the sixth ray 515g is again defined as the first display ray. Reference numeral 515g also refers to the first display light. Then, the first display ray 5 15g is incident on the first transparent film 217 of the film 200 for compensating for the optical characteristics. In this day, the first display light 5 is incident on the eyes of the user via about two paths. The first display light 515g incident on the first transparent film 217 in the first path is incident into the eyes of the user via the second transparent film 21〇 coupled to the first transparent film 217. Meanwhile, when the first display light 515g sequentially passes through the first and second transparent films 217 and 210, the light path is not changed. This is caused by the fact that the refractive index of the second transparent film 210 as described above is substantially the same as that of the first transparent film 217. Thereafter, the first display ray 515g is defined as the second display ray 515i by the flute of the first path.

Description of the Invention (18) In the second path, the first visible light rays incident on the first transparent film 217 are inserted into the transparent film 210 through the untransparent first transparent thin film 210; the user's eyes At this time, the first display light 515 (10) is rotated from the first transparent film 217 to the air, and then reversed to the transparent film 210. When the first display light 515g is incident on the second transparent film 21 from the air, the first display is not displayed. The light 515g is refracted. Thereafter, the first display light 515g through the second path is defined as the third display light 5丨5h, $1. ^, the first-display light is converted into the second display light=or After the third display light h, 515j^, the second display light fine i or the third display light 515h, 51 people are shot in the user's eyes. The third display light 5 said, 515] is used to improve the viewing angle characteristics, and The conversion phenomenon is also reduced. Thereafter, the substantial use of the film for compensating for optical characteristics as described above will be described with reference to the simulation results. Table 1 shows the substantial effect of simulating the thinness of the light characteristic (which is shown to be reduced) Grayscale conversion phenomenon and improved viewing angle characteristics Comparative examples and examples of conditions.

Here, Fig. 12A shows the viewing angle distribution in the upper and lower directions. : The figure shows the distribution of the angle of view in the right and left directions, and the 12B is a partial enlarged view of the left part of the 12th figure. The 12B shows the gray voltage selected from the range of 17 to 5 〇¥ The values (1.7V, 1.9V, 2_2V, 2.5V, 2.8V, 3.3V, 5.0V) are plotted for the angle of view and the gradation conversion phenomenon when applied individually. Refer to Figure 12 for compensation of light. The characteristic film 2 is not used in the case of the LCD 800, although a higher gray voltage is applied, but a gradation conversion phenomenon occurs, during which the brightness is lowered by 2 〇 to _6 。. 13C is shown in the second comparative example of the first table (that is, the state in which the transparent film 217 is not used for the LCD 800 and only the second transparent film 21 is simply used, or the h/H is 100%). The viewing angle and the mapping of the grayscale phenomenon. Here, Fig. 13A shows the distribution of the viewing angles in the upper and lower directions. Fig. 13c shows the distribution of the viewing angles in the left and right directions, and Fig. 13B is a partial enlarged view of the left part of Fig. 13A. It also provides seven gray voltages. Referring to Figures 13A and 13B, the front view is almost non-existent. This means that the display operation is not performed in the direction before the LCD 800. This is an important missing indicator. As shown in Fig. 13C, the viewing angle characteristics in the right and left directions are also very low. However, the problem of the gradation conversion phenomenon is improved as compared with the Figs. 12A to 12C. In summary, only the second transparent film 21 has failed to achieve high display quality. This paper scale applies to China National Standard (CNS) A4 specification (210 X 297 public Chu) 22 (Please read the note on the back first ^ Write this page), fTl 1307421 A7 ____B7_ V. Invention description (20) However, '第14A to 14C are shown in the condition of Example 1 of Table 1 (i.e., the viewing angle and gray scale of the film 200 for which light characteristics are compensated (where h/H is 30%) is applied to the upper surface of the LCD 800). Conversion phenomenon. Referring to Figures 14A and 14B, the front viewing angle is significantly improved compared to Figures 13A and 13B. Specifically, as shown in Fig. 14B, the gradation conversion phenomenon hardly occurs. This means that the display quality is significantly improved. 15A to 15C show the conditions of the second specific example of the first table (i.e., the film 200 for compensating for optical characteristics (where h/H is 30% and the α and /3 angles are different from each other) are used for the LCD. 800 upper surface) viewing angle and grayscale conversion phenomenon. In terms of party membership, there are some slight differences between Examples 1 and 2. However, in the example i, the angle of view and the top and bottom viewing angles are completely and significantly improved. Furthermore, the problem of the gradation conversion phenomenon is almost solved. According to the present invention, by using the film for compensating for light characteristics, the viewing angle is remarkably improved and the gradation conversion phenomenon is solved, thereby improving the display characteristics. Moreover, the method of manufacturing the film is improved, and therefore, a simple method of fabricating a film for compensating for light characteristics is employed. Although the present invention has been described in detail, it is understood that various modifications, alternatives and changes may be made without departing from the spirit and scope of the invention as defined by the appended claims. 23 The paper size is applicable ^; 1307421 A7 B7 V.
