Description

1335270 IX. EMBODIMENT OF THE INVENTION The present invention relates to a film attaching method and apparatus for attaching a sheet-like film sized to a bonded substrate to a substrate. [Prior Art] In the liquid crystal In the production process of a display panel, a plasma display panel, etc., it is possible to improve the brightness and darkness contrast or color reproducibility, block electromagnetic waves or infrared rays emitted from the panel, prevent peripheral images from being reflected in the screen, and prevent panel damage. A functional film (hereinafter referred to as a film) is attached to the surface of a liquid crystal display panel or a plasma display panel (hereinafter referred to as a substrate) in a state in which two glass sheets are bonded to each other, thereby achieving good image quality. In the case of attaching a film, a film-attaching device in which a sheet-like film having a size corresponding to the bonded substrate is supplied from the upper side of the substrate is used, and the film is attached. Since the film is coated with the adhesive material, the protective film is used to cover the surface of the adhesive material, so that the foreign matter can be prevented from adhering before use, or the adhesive material can be prevented from being deformed, or the films can be overlapped with each other. In such a film, the adhesive protective film is set upward (attached) to the adsorption holding stage, and the adhesive protective film is peeled off before attaching. The adsorption holding stage is reversed and the adhesive of the film is exposed. . In order to bring the attached end closer to the substrate, the film is tilted by pressing with a roll, and the front end is attached, and the substrate is moved in the direction in which the film is pulled out, whereby the film is attached. -5- 1335270 At this time, the film is slid down to the base of the base plate by the pressing roller, and is slid down on the adsorption holding table while being adsorbed and held on the adsorption holding table. Those who show such a technique are described in Patent Documents 1 to 3 below. [Patent Document 1] Japanese Laid-Open Patent Publication No. JP-A No. 2003-276091. [Patent Document 2] JP-A-2004- 1 493 Problem to be Solved In order to attach a film to a substrate, it is necessary to hold the film on the substrate while the substrate is placed in a planar shape. The film is attached by holding the film and the substrate held by the roller, and the film is attached by rotation of the pressure roller. Therefore, the film must be adsorbed and held and slid on the surface of the adsorption member in the adsorption holding state. φ A slight abrasion powder is generated on the substrate which is arranged in a planar shape because the surface of the adsorption member slides on the film. Further, dust is generated from the mechanism portion on which the film adsorption member is operated, on the substrate arranged in a planar shape. Tiny abrasion powder or dust falls to the surface of the substrate which is arranged in a planar shape and remains between the film and the substrate. In this case, the light transmitted through the dust or the dust mites and the surrounding air bubbles is blocked or scattered, and the desired image quality cannot be obtained, resulting in a deterioration in the image quality or a decrease in the yield. This problem is not particularly limited to the production of liquid crystal display panels or plasma display panels, and care must be taken when attaching various thin film-like films. -6- 1335270 Therefore, the object of the present invention is to provide a film attaching method in which a small amount of abrasion powder or dust does not fall to the surface of the substrate during the attachment of the film, and the yield is not lowered. Its device. (Means for Solving the Problem) The film attaching method of the present invention which achieves the above object is characterized in that a sheet-like film having a size comparable to a substrate is attached to a substrate after peeling off a protective film provided on an adhesive surface of the film. The substrate raising means standing in the vertical direction while holding the substrate, and the suction plate corresponding to the front end suction plate of the front end portion of the film and the film corresponding to the film other than the front end portion are sucked and held on the opposite side of the protective film. The peeling protective film is erected in a vertical direction in a state in which the front end suction plate and the suction plate correspond to the front end portion of the film to hold the film, and the film is bonded to the front end portion of the film corresponding to the vertically held substrate. The front end portion is pressurized by a pressure roller provided on the suction plate, and the suction plate is moved to the lower side in the vertical direction while the pressure of the pressure roller is maintained, and the film is attached to the substrate. Moreover, the film attaching apparatus of the present invention which achieves the above object is characterized in that the film is raised in the vertical direction by the adsorption plate corresponding to the front end adsorption plate of the front end portion of the film and the film corresponding to the film other than the front end, and the substrate is placed in the vertical direction. The amount of the tilt is maintained in the vertical direction and on the side of the suction plate, and the pressure roller is moved to the lower side in the vertical direction at the position of the front end of the film by pressing the roller, whereby the roller is moved along the inclination of the substrate. The film is attached to the substrate by pressing the roller at a constant angle of the film from the substrate from the front end to the end of the film. 1335270. [Effects of the Invention] According to the present invention, since the substrate is attached to the film in a state in which it is perpendicular to the film, there is no minute abrasion powder or self-sliding due to the sliding of the surface of the adsorption member on the film. When the mechanism of the film adsorption member is moved, the dust is dropped on the surface of the film or the surface of the display panel, and abrasion of powder or dust or dust bubbles around the dust occurs, and the thin φ film can be attached with good yield. On the substrate. [Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to Figs. 1 to 7 . In addition, in the entire drawing, the same reference symbol is given to the same object. Fig. 3 is a schematic plan view showing an optical film attaching apparatus to which the present invention is applied. A is a panel input conveyor portion, B is an optical film attachment portion, and C is a panel discharge carrier portion. Φ Attaching the optical film 1 to the display panel (base) 2, the display panel 2 is attached to the panel transport jig 15 in advance, and the panel is transported from the panel to the transport unit A to the optical film attaching portion B. The optical film attaching portion b is carried out. After the attachment is completed, it is sent out to the panel discharge conveyor portion. Fig. 1 is a schematic view of the main portion (optical film attachment portion B) of the optical film attachment device to which the present invention is applied. The optical film attaching device is a device that attaches an optical film (film) 1 to an image display surface of a display panel (substrate) 2. The optical film adsorption transport mechanism of the large cymbal by the panel holding upright mechanism B1' and the adsorption plate 22 and the front end adsorption plate 39 and the adsorption plate vertical -8 - 1335270 mechanism and the front end adsorption plate disengagement means and the adsorption plate release means B2, a pressure roller mechanism including a pressure roller and a pressurizing mechanism, and a pressing roller mechanism including a pressing roller that suppresses bending of the pressure roller and a pressurizing mechanism. Hereinafter, the configuration of each unit will be described in order. Here, the optical film attaching device is a type or structure of the display panel 2, and the thickness thereof is not particularly limited. For example, a PDP display panel that can be used for displaying a portrait of a PDP (plasma display panel) or a filter independent of the display panel The filter is manufactured using a single-panel glass substrate or a display panel of an LCD (liquid crystal display). First, the optical film 1 will be described. The optical film 1 has various functions such as enhancing the contrast of light and darkness or color reproducibility, blocking electromagnetic waves or near-infrared rays emitted from the panel, preventing surrounding images from being reflected on the screen, and preventing damage to the panel. As shown in FIG. 2, the optical film 1 is composed of an antireflection film 3, a colored film 4, and an electromagnetic wave shielding film 5. Further, the electromagnetic wave shielding film 5 is coated with an adhesive 6 for attaching to the display panel 2, and a protective film 7 for protecting the adhesive 6 is attached, and has appropriate rigidity. The thickness, material, combination, and the like of the respective film layers 3 to 5 are not particularly limited. In the optical film 1 configured as described above, the protective film 7 is peeled off when attached to the display panel 2, and the adhesive 6 is exposed (see Fig. 6 (1)). Then, the optical film 1 and the display panel 2 are properly aligned, and the adhesive 6 is attached to the display panel 2 to be attached. First, explain the panel holding mechanism. -9 - 1335270 The panel holding upright mechanism, as shown in Fig. 1, is provided with a carrier support frame 9, a rotating shaft 10, a lev el jack l 1 , a conveyor or a l 2 on the base frame 8 , cylinder (cylinder) 13. The base frame 8 is a base on which an optical film attaching device is formed, and has a flat shape. In the base frame 8, a carrier support frame 9 for securing a necessary space is provided in order to secure the height position of the transporter 12 and the cylinder 13 for arranging the transporter 12. The cylinder 13 is disposed in such a manner as to be able to connect the base frame 8 and the carrier 12. On the upper surface of the carrier support frame 9, a rotating shaft 1 which is a center of rotation of the carrier 12 during the standing operation and a horizontal crown 11 which determines the horizontal position when the carrier 12 is in a horizontal state are disposed. By the rotation shaft 10 and the horizontal gold dome 11, the vertical movement position and the horizontal state position of the conveyor 12 can be accurately reproduced. The transporter 12 moves the panel transport jig 15 to which the display panel 2 is fixed to the front side from the back side of the paper surface of Fig. 1 by a panel transport jig transport motor (not shown). Then, it is taken up by the transport roller 16 provided on the carrier 12, and after moving to a predetermined position, the panel transport mechanism 15 can be fixed by the panel lock mechanism 14 disposed in the four directions of the transporter 12. When the display panel 2 is mounted on the upper side, the panel transport jig 15 can be mounted in a state in which the panel display printed circuit board 2a or the like is mounted on the back side of the display panel 2, and the panel display is not mounted. A panel supporting member 15a is provided at a position of the printed substrate 2a. Further, in the panel transport jig 15, the mounting hole for the panel supporting member 15a is provided so as to be compatible with the display panel 2 of various shapes and sizes, whereby the degree of freedom of application of the optical film attaching device is increased. Further, as shown in FIG. 3, the panel transporting the display panel 2 is fixed, and the fixture 1 5 is moved from the position on the right side of the paper of FIG. 3 to the position of the position received by the transporter 12, A panel cleaner 17 for cleaning the surface of the panel is provided. The panel cleaner 17 is a rotating brush mode. In FIG. 3, the direction of rotation of the brush is a reverse direction for the display panel 2 to travel from right to left. Thereby, the dust on the surface of the display panel 2 can be swept away to be connected to the dust collector of the panel cleaner to be sucked and removed. Since the rotating brush used here rubs the surface of the display panel 2, it is possible to prevent the display panel 2 from being charged by using a conductive material. The panel cleaner 17 is not particularly limited to the rotary brush method, and any method can be selected in consideration of the size of the dust on the surface of the display panel 2 and the state of adhesion. For example, an adhesive roller method or an ultrasonic dry cleaning method can be used. Next, the optical film adsorption transport mechanism will be described. The optical film adsorption transport mechanism is disposed on the left side of the above-described panel holding and standing mechanism as shown in Fig. i. As shown in FIG. 2, the optical film adsorption transport mechanism includes an upper frame 18, a lift guide 19, a lift plate 20, a ball screw 21, an adsorption plate 22, and a suction plate moving frame on the base frame 8. twenty three. The lifting guides 19 are provided at four places by the base frame 8 and the upper frame 18 to hold the lifting plate 20 horizontal. The lift plate 20 has a flat plate shape, and a ball screw nut 24 of the ball screw 21 supported by the base frame 8 and the upper frame 18 is attached. Under the rotary drive servo motor 26, the ball screw 21 is rotated via the gear case 25, so that the lift plate 20 can be moved in the vertical direction along the lift guide 19, so that the stopped position after the movement can be correctly reproduced 1335270. The lift plate 20 is provided with a linear guide 27 provided in the left-right direction of Fig. 1, and the suction plate moving frame 23 is movable in the left-right direction of Fig. 1 by operating the cylinder 46 provided on the lift plate 20. The adsorption plate 22 is disposed on the adsorption plate moving frame 23 via the rotating shaft 28. Further, the suction plate 22 is provided with a pressure roller mechanism 29 and a pressing roller mechanism 30 which are attached to the display panel 2 by pressing the optical film 1. Further, the pressure roller mechanism 29 and the pressing roller mechanism 30 will be described later. Further, in the suction plate moving frame 23, the cylinder 31 is set to be freely rotatable. The shaft end of this cylinder 31 is rotatably coupled to the suction plate 22. By operating the cylinder 31, the suction plate 22 can stand in the vertical direction with the rotation shaft 28 as the center. A method of adsorbing and fixing the optical film 1 to the adsorption plate 22 will be described with reference to Fig. 4 . A plurality of adsorption holes 32 are arranged in the adsorption plate 22 so as to be able to penetrate the adsorption plate 22. The row of the adsorption holes 32 is divided into a plurality of adsorption regions 33 in the width direction of the optical filter 1, and the suction pipes 34 are connected to the respective regions. An opening and closing valve 35 is provided in each of the suction pipes 34. The suction pipes from the opening and closing valve 35 are merged into one to be connected to the optical filter fixing bio 6 6 . The optical filter fixing supercharger 36 is rotationally driven to supply a negative pressure to the adsorption holes 32 provided in the respective regions, thereby adsorbing and holding the film. The adsorption plate 22 is formed by selecting an adsorption region corresponding to the size of the optical film 1 for bonding, and can prevent leakage from the adsorption hole 32, and is suitable for a plurality of optical filter sizes. Further, the optical film adsorption fixing -12-1335270 presser 36 is provided with an inverter 37, and the suction force of the adsorption region 33 can be arbitrarily changed by controlling the number of revolutions. With such a configuration, the suction force of the high vacuum suction can be applied when the protective film (shown in FIG. 2) is peeled off while the optical film 1 is being adsorbed and held, so that the optical film 1 is not picked up from the adsorption plate 2 2 . . Further, when the optical film 1 is attached to the display panel 2, the suction force of the low vacuum suction is applied to the optical film 1, whereby the adsorption sheet 22 can be moved while the optical film 1 is held by the adsorption sheet 22. . In the adsorption plate 22 shown in Fig. 1, a tip end adsorption plate 39 is provided via a rotating shaft 38 on the side of the attachment end of the optical film 1 (the one end portion of the film). The front end suction plate 39 is provided with the same adsorption holding mechanism as the adsorption plate 22. Further, when the current end adsorption plate 39 adsorbs and holds the optical film 1 placed on the adsorption plate 22, it is positioned at a position that coincides with the surface on which the adsorption plate 22 is formed, and the front end side of the optical film 1 is adsorbed and held by suction. . Further, a region other than the front end portion of the optical film 1 is suction-held by suction by the suction plate 22. Further, as will be described later, after the protective film attached to the optical film 1 to be adsorbed and held is peeled off, the tip end of the optical film 1 is attached to the display panel 2 by the pressure roller mechanism 29. At this time, in order to secure the pressing space of the pressure roller mechanism 29, the suction holding of the distal end suction plate 39 is released. The suction release of the front end suction plate 39 is performed by closing the opening and closing valve 35 provided in the middle of the suction pipe 34 of the optical film adsorption fixing supercharger 36 shown in Fig. 4, and stopping the supply of the negative pressure to be released. The cylinder (not shown) is rotated away from the optical film 1 by being retracted around the rotating shaft 38. The front end suction plate is released by means of the rotating shaft, the cylinder, and the like. Further, the front end suction plate 39 is provided with a mark -13 - 1335270 mark 55 corresponding to the size of the optical film. The optical film 1 is placed at the positioning mark position 55, whereby the optical film 1 can be attached to a desired position of the display panel 2. The pressure roller mechanism 29 and the pressing roller mechanism 30 are described with reference to Fig. 5 (a). The pressure roller mechanism 29 is attached to the base 43 provided on the adsorption plate 22, and stands upright from the adsorption plate 22 to be vertically moved. The direction is constituted by the pressure roller 40, the linear guide 41, and the cylinder 42. First, the front end suction plate 39 is rotated about the rotation shaft 38 by a cylinder (not shown) to separate and retract the optical film 1. The pressure roller 40 can be moved in the vertical direction in Fig. 5(a) via the linear guide 41 by the action of the cylinder 42. The pressure roller 4 is a rotary drive mechanism. After the optical film 1 and the display panel 2 are sandwiched, the pressure roller 22 is moved, and the pressure roller 40 is driven. The size of the pressure roller 40 is not limited, and can be set in consideration of the strength of the display panel 2 or the necessary pressing force of the optical film 1. The pressing roller mechanism 30 is attached to the base 43 provided on the suction plate 22, and is erected in the vertical direction from the suction plate 22 to press the drum 44 and the guide rod cylinder 45. When the width of the display panel 2 is large or when a high pressing force is required, the pressure roller 40 becomes long, and the bending of the center portion becomes large, and it is impossible to maintain an equal pressing force in the width direction. Then, in order to suppress the bending, as shown in Fig. 5 (b), the pressing roller 44 can be pressed against the pressure roller 40 with the pressing roller 44 as a supporting roller in a state where the pressure roller 40 is in contact with the optical film 1. The surface of the pressure roller 40 is formed of an elastic rubber layer, but the material thereof is not particularly limited, and may be appropriately selected depending on the optical film 1. PET Thin -14- 1335270 Membrane and release mold or conductive rubber is the most suitable. Further, the rubber hardness is preferably a soft hardness in order to absorb the warpage of the display panel 2. Next, an operation preparation operation of the optical film attaching device having the above configuration in which the optical film 1 is attached to the display panel 2 will be described with reference to Fig. 3 . First, in order to attach the optical film 1 to the display panel 2, the display panel 2 is attached to the panel transport jig 15 in advance, and is placed in the panel loading and transporting unit A. Next, by the operation of the panel input button, the panel transport jig 15 starts moving to the position of the optical film attaching portion B. Then, after the predetermined position of the optical film attaching portion B is stopped, the panel locking mechanism 14 (refer to Fig. 1) is positioned. At this time, the display panel 2 is cleaned by the panel cleaner 17 provided on the input side of the optical film attaching portion B, and the optical film 1 is placed on the adsorption plate 22 at the optical film attaching portion B. And the front end adsorption plate 39. At this time, two of the four corners of the optical film 1 are correctly positioned on the positioning mark 55 provided on the distal end suction plate. Then, the optical filter 1 is adsorbed and held by operating the adsorption plate 22 and the adsorption start of the front end adsorption plate 39. Then, in the state in which the optical film 1 is adsorbed and held, the protective film 7 (shown in Fig. 2) constituting the optical film 1 is peeled off by a protective film peeling means (not shown) to expose the adhesive 6. According to the above, the operation preparation for attaching the optical film 1 is completed. Next, a method of attaching the optical film 1 to the display panel 2 by using the optical film attaching device having the above configuration will be described with reference to Fig. 6 . Fig. 6 (1) shows the state in which the optical film 丨 and the display panel 2 are ready for operation (S ) -15 - 1335270. In this state, the attaching action is started by operating the automatic start buckle. In order to attach the optical film 1 to the display panel 2, first, in a state where the adsorption film 22 and the tip adsorption plate 39 adsorb the optical film 1, the cylinder 31 is rotated about the rotation axis 28 to the vertical state. Then, the display panel 2 attached to the panel transport jig 15 is rotated by the cylinder 13 around the rotating shaft 10 in a state where the panel transport jig 15 and the transporter 12 are fixed by the panel lock mechanism 14 direction. The display panel 2 is held in an inclined state by a predetermined angle from the vertical position to the forward direction of the cylinder 13 and the stopper (not shown). At this time, the angle Θ formed by the optical film 1 and the display panel 2 shown in Fig. 6 (2) is preferably 10 Å. When the angle between the optical film 1 and the display panel 2 is small, when the optical film 1 is attached, the pressure roller 40 comes into contact with the display panel 2 before the optical film 1 is pushed, and bubbles or wrinkles are generated. Further, when the angle is too large, a force which is opposed to the surface of the adsorption plate 22 due to the rigidity of the optical film 1 acts to cause adsorption and breakage, causing the optical film 1 to come into contact with the display panel 2, and bubbles or wrinkles occur. Next, in order to align the optical film 1 to the position of the display panel 2, the suction plate 22 supporting the adsorption plate 22 is lifted and lowered, and the front end of the optical film 1 can be positioned to come to the bonding position of the display panel 2. At this time, the lifting plate 20 can be moved by the servo motor 26 and the ball screw 21 to achieve good attachment positional accuracy. Further, when the display panel 2 of a plurality of sizes is used, the position of the front end of the optical film 1 can be easily and accurately aligned. Next, the optical film 1 of the front end suction plate 39 is opened and held, and -16 - 1335270 is rotationally moved around the turn δ 38 by a cylinder (not shown) to be separated from the optical film 1. Thereby, the pressing space for attaching the optical film 1 to the pressure roller 40 of the display panel 2 is ensured. Then, the pressure roller 40 is moved forward to the side of the optical film 1 to stop at the same position as the adsorption surface of the adsorption plate 22. Thereby, the same surface is formed on the adsorption surface side of the optical film 1. Further, the pressing roller 44 is moved forward to the back side of the pressure roller 40, and is positioned in contact with the pressure roller 40. Thereby, it is possible to suppress the bending of the pressure roller which occurs when the pressure roller 40 is pressed in order to attach the optical film 1 to the display panel 2. And 'can prevent air bubbles from occurring between the display panel and the optical film. Next, as shown in Fig. 7 (1), the suction plate moving frame 23 provided to the elevation plate 20 via the linear guide 27 is moved to the display panel 2 side by the cylinder 46. Thereby, the pressure roller 40 is pressed against the display panel 2 via the front end of the optical film 1, and the optical film 1 is attached to the display panel 2. In this state, as shown in Fig. 7 (2), the servo screw 26 rotates the ball screw 21, whereby the lift plate 20 is moved downward. When the elevating plate 20 is moved downward, the pressure roller 40 moves while holding the optical film 1 against the display panel 2. Thereby, the adhesive material 6 (refer to Fig. 2) of the optical film 1 is adhered to the display panel 2. Then, the optical film is pulled out by the adsorption force of the holding mechanism of the optical film 1 of the adsorption plate 22 to be described later. Thereby, the optical film 1 is pulled out from the adsorption plate, and the optical film 1 is pulled out while the display panel 2 is attached. When the display panel 2 is attached, the pressing roller 40 holds the optical film. 1 is pressed against the state of the display panel 2. As a result of -17-1335270, the optical film 1 is moved downward along the inclination of the panel 2 of the invention. Thereby, the angle Θ between the optical film 1 and the display panel 2 is maintained at the same angle from the front end to the terminal end, so that it is possible to perform an inconsistent good attachment without variation in the attachment conditions. Fig. 7 (3) shows a state in which the optical film 1 is attached to the display panel 2. The suction plate 22 which has been pulled out of the optical film 1 to complete the downward movement is returned to the horizontal state. Then, it is raised to a predetermined height position and returned to the initial position for carrying the second optical film. Further, the display panel 2 to which the optical film 1 is attached is returned to the horizontal state by the cylinder 13. Then, the panel transport jig 15 of the panel lock mechanism 14 is released and fixed by the transporter 12 to the panel discharge transporter unit C (see Fig. 3) to complete a series of attach operation operations. The method of supplying the optical film 1 to the adsorption plate 22 or the panel carrier portion for supplying and discharging the display panel 2 described in the above-described series of operation operations is not particularly limited, and an automatic supply machine may be used for the supply of the optical film 1. The transport trolley is used for the supply and discharge conveyor sections. Next, the holding mechanism of the optical film 1 of the adsorption plate 22 will be described. As shown in Fig. 8 (1), when the tip end of the optical film 1 is attached to the display panel 2, the surface of all the adsorption holes 32 provided in the adsorption plate 22 is covered by the optical film 1, so that the adsorption force acts. . Next, as shown in Fig. 8 (2), the adsorption plate 22 for attaching the optical film 1 to the display panel 2 is lowered. Thereby, the optical film 1 is adhered to the display panel 2 and slid to the surface of the adsorption plate 22. At this time, the -18-1335270 on-off valve 35 connected to the pipe of the adsorption hole 3 2 in which the optical film 1 is moved to the display panel 2 side is closed. Thereby, the adsorption force of the adsorption holes 32 of the optical film 1 remaining and adsorbed by the leakage of the air from the adsorption holes 32 is prevented from being lowered. The opening and closing control timing of the opening and closing valve 35 is determined by the amount of drop of the suction plate 22. Since the moving mechanism employs the servo motor 26 and the ball screw 21, accurate opening and closing control can be performed by high-accuracy position information. Further, as the attachment of the optical film 1 to the display panel 2 approaches the terminal from the front end, the number of adsorption holes 32 for which the adsorption force acts on the optical film 1 becomes small. Therefore, in order to keep the adsorption holding force constant, the negative pressure supplied to the adsorption holes can be increased to increase the adsorption force in order. That is, the suction force reduction is performed by the position information of the adsorption plate 22 of the servo motor 26 and the ball screw 21, and the number of revolutions of the optical film adsorption fixing pressure accumulator 36 is automatically controlled by the inverter 37. Thereby, the optical film 1 is kept in the same attachment condition from the front end to the end, and the attachment without bending or air bubbles can be performed. Further, since the adsorption holding force of the optical film 1 can be arbitrarily selected by the inverter 37, it is possible to prevent the optical film 1 from being injured when it slides on the surface of the adsorption plate 22. Further, the material of the adsorption plate is not particularly limited. However, if the surface of the adsorption film is hard chrome-plated, the optical film 1 can be effectively prevented from being injured. According to the above, it is possible to obtain a high-quality attached product in which the optical film 1 is free from bending or air bubbles from the front end to the end of the display panel 2, and the surface is free from scratches.
