Description

  The present invention relates to an electro-optical device, an electronic apparatus, and an electro-optical device manufacturing method, and more particularly to a holding structure suitable for holding an electro-optical panel on a frame.

  In general, an electro-optical device in which an electro-optical panel such as a liquid crystal display panel is held by a frame body (frame) made of plastic or the like is known. For example, in an electro-optical device mounted on a small electronic device such as a cellular phone, the electro-optical panel 10 is held in a resin frame 20 as shown in FIG. The electro-optical panel 10 includes liquid crystal (not shown) sealed between a pair of transparent substrates 11 and 12 made of glass or the like, and polarizing plates 13 and 14 are attached to the outer surfaces of the substrates 11 and 12. A semiconductor 15 made of an IC chip or the like is mounted on a substrate overhanging portion 11T that projects from the outer edge of the other substrate 12 of the other substrate 11 to the outer peripheral side. A wiring board 16 made of a flexible wiring board (FPC) is mounted on the board overhanging portion 11T, and passes over the outer surface of the frame body 20 and is bent to the back side.

  The frame 20 has a frame shape having a flat support surface 21 formed and exposed along the outer periphery of the panel housing portion 20A provided on the upper portion thereof, and a step surface 22 formed on the outer peripheral side of the support surface 21. The outer surface of the step surface 22 is positioned so that the electro-optical panel 10 is disposed, and the outer surface of the electro-optical panel 10 has a light-shielding double-sided adhesive tape 23 on the support surface 21. Fixed through.

  Inside the frame body 20, the illumination device 30 is accommodated in an illumination accommodation portion 20B provided below the panel accommodation portion 20A on which the electro-optical panel 10 is held and fixed. The illumination device 30 includes a light source 31 such as an LED, and a light guide plate 32 that emits light emitted from the light source 31 from an incident surface 32a and emits the light from the light exit surface 32b while propagating the light inside. A reflection sheet 33 disposed on the back surface of the light guide plate 32 opposite to the light exit surface 32b, and an optical sheet 34 (light diffusion sheet, light collection sheet, etc.) disposed on the light exit surface 32b of the light guide plate 32. ). The light source 31 is conductively connected to the wiring board 16.

  As shown in FIG. 14 (b), the outer peripheral portion of the electro-optical panel 10 is bonded and fixed by a double-sided pressure-sensitive adhesive tape 23 having a light-shielding property attached on the support surface 21 of the frame body 20. This double-sided pressure-sensitive adhesive tape 23 is formed, for example, by forming pressure-sensitive adhesive layers on both sides of a base sheet in which a white film and a black film are laminated. The double-sided adhesive tape 23 has a function of preventing the illumination light from the illumination device 30 from leaking from the outer edge translucent region 10E between the light shielding film 17 provided on the outer peripheral portion of the electro-optical panel 10 and the panel end surface 10e. Have. Usually, a gap 10g is provided between the panel end surface 10e of the electro-optical panel 10 and the step surface 22 to ensure an assembly margin.

An electro-optical device having the panel fixing and holding structure as described above is described in, for example, Patent Document 1 below.
JP 2007-298622 A

  However, in the above-described electro-optical device, the width of the frame region outside the display region of the panel has been reduced due to recent progress in downsizing of electronic equipment on which the electro-optical device is mounted and importance of design. There is a growing demand for narrower frames. Due to this requirement, various problems have also occurred in the structure for holding the electro-optical panel on the frame. For example, the width Wd of the support surface 21 of the frame 20 shown in FIG. 14B is becoming smaller year by year with the width of the outer peripheral portion (the portion outside the display area) of the electro-optic panel in order to narrow the frame. For this reason, the width Wt of the double-sided pressure-sensitive adhesive tape 23 must be reduced, so that the adhesion area of the electro-optical panel 10 cannot be sufficiently ensured, and the adhesive strength is lowered. There is a problem that the panel 10 comes off the frame body 20.

  Further, when the electro-optical panel 10 is manufactured by cutting the mother substrate, it is extremely difficult to reduce the width of the outer edge translucent region 10E due to variations in the cutting process. For this reason, if the width of the outer peripheral portion of the electro-optical panel 10 is reduced and the width Wd of the support surface 21 is reduced, there is a possibility that light leakage from the outer edge translucent region 10E cannot be prevented.

  Further, since the width Wd of the double-sided pressure-sensitive adhesive tape 23 needs to be smaller than that due to the narrowing of the width Wd of the support surface 21, there is a possibility that the blanking process at the time of manufacturing the double-sided pressure-sensitive adhesive tape may not be possible. However, the price of the double-sided pressure-sensitive adhesive tape 23 increases, and the work of bonding the double-sided pressure-sensitive adhesive tape 23 to the support surface 21 becomes extremely difficult, which causes problems such as an increase in material costs and a decrease in productivity. .

  Accordingly, the present invention solves the above-described problems, and an object thereof is to provide a structure of an electro-optical device that can ensure adhesive strength even by narrowing the width of a support surface by narrowing the frame.

  In view of such circumstances, the electro-optical device according to the first aspect of the invention includes an electro-optical panel and a frame body that holds the electro-optical panel, and the frame body is supported along the outer periphery of the accommodating portion of the electro-optical panel. In the electro-optical device having a surface, and the outer peripheral portion of the electro-optical panel is held on the support surface, the outer peripheral portion of the electro-optical panel and the support surface are bonded via a light-shielding adhesive. The bottom surface and the outer end surface of the outer periphery of the electro-optical panel are bonded together to the adhesive.

  According to this invention, the outer peripheral portion of the electro-optical panel and the support surface of the frame body are bonded via the light-shielding adhesive, and the bottom surface and the outer end surface of the outer peripheral portion of the electro-optical panel are bonded together to this adhesive. By doing so, the bonding range can be expanded, so that the bonding strength can be increased. In addition, since the decrease in the bonding area can be suppressed even when the width of the support surface is reduced, the bonding strength can be ensured.

  In addition, since the light-shielding adhesive is adhered to the outer end surface of the outer peripheral portion of the electro-optical panel, the light-shielding range can be expanded compared to the conventional one, so that light leakage can be reduced and the width of the support surface is reduced. However, light leakage can be suppressed.

  Furthermore, since it is possible to avoid the difficulty of punching double-sided adhesive tape and the difficulty of sticking work, it becomes possible to easily narrow the frame of the electro-optical device and reduce the manufacturing cost, The production efficiency can be improved.

  An electro-optical device according to a second aspect of the present invention includes an electro-optical panel and a frame body that holds the electro-optical panel, and the frame body has a support surface along an outer periphery of a housing portion of the electro-optical panel. In the electro-optical device in which the outer peripheral portion of the electro-optical panel is held on the support surface, the bottom surface of the outer peripheral portion of the electro-optical panel and the support surface are bonded with a light-shielding double-sided adhesive tape. The outer peripheral portion of the electro-optical panel and the support surface or the double-sided adhesive tape are bonded to each other on the outer peripheral side of the adhesive tape through an adhesive having a light shielding property.

  According to this invention, the outer peripheral portion of the electro-optical panel and the support surface of the frame body are bonded using the double-sided adhesive tape, and the outer peripheral portion of the electro-optical panel and the support surface or double-sided adhesive on the outer peripheral side of the double-sided adhesive tape. Since the adhesive range can be expanded by adhering to the tape with an adhesive, the adhesive strength can be increased, and even if the width of the support surface is reduced, the decrease in the adhesive area can be suppressed. Strength can be secured. Further, since the light shielding range is widened, the light shielding property can be improved, or the reduction in the light shielding property can be suppressed even when the width of the support surface is reduced.

  Moreover, since the double-sided pressure-sensitive adhesive tape exists on the inner peripheral side of the adhesive, it is possible to prevent the adhesive from leaching out to the inner peripheral side and protruding into the display area or the illumination range. Furthermore, after the electro-optic panel is bonded and fixed to the frame using a double-sided pressure-sensitive adhesive tape, it can be easily configured by applying an adhesive from the outer peripheral side, so that there is an advantage that it does not require much labor during manufacture.

  In this case, it is preferable that the adhesive is bonded to at least a part of the outer end surface of the outer peripheral portion of the electro-optical panel. The reason is the same as in the first invention. In particular, it is more desirable that the adhesive is bonded to the bottom surface and the outer end surface of the outer peripheral portion of the electro-optical panel.

  In each of the above inventions, the frame body has a step surface extending from the outer edge of the support surface to the surface side opposite to the surface facing the support surface of the electro-optic panel on the outer peripheral side of the support surface. The adhesive is preferably bonded to the stepped surface. According to this, not only the bottom surface and the outer end surface of the outer peripheral portion of the electro-optical panel are bonded to the support surface of the frame by an adhesive, but also the outer peripheral portion of the electro-optical panel is supported by the adhesive or the double-sided adhesive tape. In addition to bonding to the step surface, the outer end surface of the electro-optical panel is bonded to the step surface via an adhesive, thereby further expanding the bonding range and the light shielding range.

  Here, when the outer peripheral portion of the electro-optical panel is bonded onto the support surface of the frame body using a light-shielding adhesive as in the present invention, the uncured adhesive is usually attached to the outer peripheral portion of the electro-optical panel or The electro-optical panel is applied to the frame body, and then the electro-optical panel is mounted on the frame body such that the outer periphery of the electro-optical panel is disposed on the support surface of the frame body. At this time, since the uncured adhesive has fluidity, the adhesive may bleed inward from a region located on the step surface of the outer peripheral portion of the electro-optical panel, and may protrude into the display region or the illumination range. is there. Therefore, the present inventor adopted the following configuration in order to solve such a problem. That is,

  In each of the above inventions, it is preferable that a spacer is disposed between the bottom surface of the outer peripheral portion of the electro-optical panel and the support surface in the adhesive. According to this, since the space between the bottom surface of the outer peripheral portion of the electro-optical panel and the support surface is regulated and secured by arranging the spacer, if the amount of adhesive and the application range are defined to some extent, the frame Since the thickness of the adhesive when the electro-optical panel is mounted on the body is controlled, the spread degree of the adhesive can be set, and the reproducibility of the adhesive range and the adhesive strength can be improved. Therefore, for example, it is possible to prevent the adhesive from protruding into the display area or the illumination range. Moreover, the reproducibility of the adhesive strength is improved by controlling the thickness of the adhesive.

  Moreover, it is preferable that the said support surface is formed with the recessed part which accommodates a part of said adhesive agent. According to this, since the concave portion is provided on the support surface and a part of the adhesive is accommodated in the concave portion, the spread range of the adhesive can be controlled. For example, to the inner peripheral side of the adhesive It is possible to prevent the adhesive from protruding outside the range of the support surface while ensuring the spread of the material within the necessary range.

  In this case, it is preferable that the concave portion is a concave groove having a shape extending along the outer periphery of the electro-optical panel. According to this, since the concave portion is a concave groove having a shape extended along the outer periphery of the electro-optical panel, the adhesive is entirely formed in the extending direction of the support surface formed along the outer periphery. The spread range can be controlled.

  Further, it is desirable that the support surface is provided with an inclined guide groove that joins the concave portion from the outer peripheral side and is inclined from the surface side of the support surface to the bottom side of the concave portion. According to this, since the adhesive flows preferentially to the recess through the inclined guide groove, the effect of controlling the spread range of the adhesive by the recess can be enhanced. In this case, by applying a method in which the adhesive is discretely applied to the inclined guide groove or the outer peripheral side thereof, and then the electro-optic panel is attached to the frame, the adhesive is further removed along the inclined guide groove. Since it surely flows into the recess, the effect of the recess can be further enhanced.

  In the present invention, it is preferable that the adhesive has an inner edge shape meandering along the outer periphery of the electro-optical panel on the support surface. According to this, since the inner edge shape of the adhesive meanders, there is a flow margin of the adhesive in the meandering valley portion on the support surface, while the adhesive from the support surface is present in the meandering peak portion. Even if it tries to protrude inside, it is suppressed by the surface tension of the adhesive, so that the valley is preferentially filled to prevent the adhesive from protruding. In addition, such a meandering shape adopts a method in which an adhesive is discretely applied on the bottom surface of the outer peripheral portion of the electro-optical panel or the support surface of the frame, and then the electro-optical panel is mounted on the frame. Thus, it is easily and reliably formed.

  Next, an electronic apparatus according to an aspect of the invention includes any of the electro-optical devices described above and a control unit of the electro-optical device.

  The method of manufacturing an electro-optical device according to the present invention includes an electro-optical panel and a frame body that holds the electro-optical panel, and the frame body has a support surface that supports an outer peripheral portion of the electro-optical panel. In the method of manufacturing an electro-optical device in which the outer peripheral portion of the electro-optical panel is held on the support surface, an uncured adhesive having light shielding properties is applied to the outer peripheral portion of the electro-optical panel or the support surface. And the electro-optical panel is mounted on the frame body so that the outer peripheral portion of the electro-optical panel is disposed on the support surface, and the outer peripheral portion of the electro-optical panel is cured by the adhesive. And a second step of bonding the bottom surface of the outer peripheral portion of the electro-optical panel and at least a part of the outer end surface to the adhesive together. It is characterized by.

  In this case, the frame body has a step surface extending from the outer edge of the support surface to the surface side opposite to the surface facing the support surface of the electro-optic panel on the outer peripheral side of the support surface, In the first step, it is preferable that at least a part of the adhesive is applied on the step surface. If the width of the support surface in the frame is reduced, it becomes difficult to apply the adhesive on the support surface, and the risk of the adhesive protruding to the inside of the support surface when the electro-optical panel is mounted increases. On the other hand, by applying an adhesive to the stepped surface (at this time, a part of the adhesive may also be applied to the support surface), it becomes easy to apply the adhesive, and the electro-optical panel is mounted. Even when the adhesive flows onto the support surface due to its own weight, a part of the adhesive remains between the panel outer end surface and the stepped surface, preventing the adhesive from protruding inside the support surface. Is done.

  According to another aspect of the invention, there is provided an electro-optical device manufacturing method including an electro-optical panel and a frame that holds the electro-optical panel, and the frame supports a peripheral surface of the electro-optical panel. In the method of manufacturing an electro-optical device in which the outer peripheral portion of the electro-optical panel is held on the support surface, a double-sided pressure-sensitive adhesive tape having light shielding properties on the bottom surface or the support surface of the outer periphery of the electro-optical panel A first step of bonding the electro-optical panel, and the electro-optical panel is mounted on the frame so that the outer peripheral portion of the electro-optical panel is disposed on the support surface, and the bottom surface of the outer peripheral portion of the electro-optical panel and the support A second step in which a surface is bonded via the double-sided pressure-sensitive adhesive tape, and an uncured light-shielding property between the outer peripheral portion of the electro-optic panel and the support surface and on the outer peripheral side of the double-sided pressure-sensitive adhesive tape Adhesive applied Is, the curing of the adhesive, and wherein a third step of the outer peripheral portion of the electro-optical panel is adhered to the support surface or the double-sided adhesive tape via the adhesive, in that it comprises.

  In this case, the frame body has a step surface extending from the outer edge of the support surface to the surface side opposite to the surface facing the support surface of the electro-optic panel on the outer peripheral side of the support surface, In the third step, it is preferable that the adhesive is applied between the step surface and the outer end surface of the outer peripheral portion of the electro-optical panel. According to this, the adhesive can be easily applied without protruding to the surroundings.

  Furthermore, a method for manufacturing an electro-optical device according to another aspect of the invention includes an electro-optical panel and a frame body that holds the electro-optical panel, and the frame body includes a support surface that supports an outer peripheral portion of the electro-optical panel. An electro-optical device manufacturing method in which an outer peripheral portion of the electro-optical panel is held on the support surface, and an uncured adhesive having light shielding properties is provided on the outer peripheral portion of the electro-optical panel or the support surface. A first step of discretely applying along the outer periphery, and the electro-optical panel is mounted on the frame body so that the outer peripheral portion of the electro-optical panel is disposed on the support surface, and by curing the adhesive And a second step in which the outer peripheral portion of the electro-optical panel and the support surface are bonded via the adhesive.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[First Embodiment]
FIG. 1 is a plan view of the electro-optical device according to the first embodiment of the present invention, FIG. 2A is a longitudinal sectional view of the first embodiment, and FIG. 2B is a cross-sectional view shown in FIG. FIG. 4 is an enlarged partial cross-sectional view showing a portion (bonding portion between an outer peripheral portion of an electro-optical panel and a support surface of a frame) in an enlarged manner.

  The electro-optical device according to the present embodiment includes an electro-optical panel 10 and a frame 20 that are basically the same as the electro-optical device illustrated in FIG. 14, and the illumination device 30 is accommodated inside the frame 20. Here, the same parts are denoted by the same reference numerals, and description thereof is omitted.

  In the present embodiment, the frame body 20 is also configured in a rectangular frame shape in accordance with the electro-optical panel 10 formed in a rectangular shape in plan view, and a panel housing portion (upper part in the drawing) for housing the electro-optical panel 10 of the frame body 20. A support surface 21 (shown by dotted line hatching in FIG. 1) having a rectangular shape in plan view provided along the outer periphery of the electro-optical panel 10 is formed on 20 </ b> A. The support surface 21 is configured horizontally in the illustrated example. The support surface 21 faces the bottom surface 10 d of the outer peripheral portion of the electro-optical panel 10. On the support surface 21, an inner edge portion 21a (FIG. 2 (FIG. 2)) partially overlaps with the outer peripheral portion of the light shielding film 17 (shown by solid line hatching in FIG. 1) provided around the display area 10A of the electro-optical panel 10. b) is defined, and an outer edge portion 21b (see FIG. 2B) is defined so as to spread outward from the outer end surface 10e of the electro-optical panel 10. However, the portion that supports the substrate overhanging portion 11T is configured to be wide corresponding to the overhanging range of the substrate overhanging portion 11T.

  As shown in FIG. 2B, a step surface 22 extending from the outer edge portion 21 b of the support surface 21 toward the substrate 12 (upper side in the drawing) when viewed from the substrate 11 of the electro-optical panel 10 is provided. The step surface 22 is configured vertically in the illustrated example. The step surface 22 faces the outer end surface 10 e of the electro-optical panel 10. The gap between the outer end surface 10e and the stepped surface 22 is set so as to always exist in consideration of variations in the external dimensions of the electro-optical panel 10.

  In the present embodiment, the outer peripheral portion of the support surface 21 and the electro-optical panel 10 (including a portion outside the display region or the drive region, in the illustrated example, the formation range of the light-shielding film 17 and the outer edge light-transmitting region 10E outside thereof). An adhesive 24 is disposed between the bottom surface 10 d and the outer peripheral portion of the electro-optical panel 10 is bonded and fixed on the support surface 21 by the adhesive 24. The adhesive 24 has a light shielding property, and for example, a black adhesive mixed with a light shielding material (fine particles) such as carbon black is used. As the adhesive 24, various adhesives such as thermosetting, moisture curable, volatile curable, and two-component curable can be used. For example, a modified silicon adhesive can be used. The adhesive 24 is preferably an adhesive having a curing characteristic other than a photo-curing resin (for example, an ultraviolet-curing resin) because light is not easily incident due to the light-shielding material. As such an adhesive, those having an adhesive strength stronger than that of the double-sided pressure-sensitive adhesive tape are generally readily available.

  In the present embodiment, the adhesive 24 is bonded not only to the bottom surface 10d of the electro-optical panel 10, but also to at least a part of the outer end surface 10e. That is, the adhesive 24 is interposed between the bottom surface 10d and the support surface 21 with a constant thickness, but rises in the thickness direction on the outer peripheral side of the outer end surface 10e, and this raised portion is on the bottom surface 10d side of the outer end surface 10e. It is glued to the part. In this way, even if the width Wd of the support surface 21 is small, the adhesion area of the electro-optical panel 10 can be increased, so that the adhesion strength can be increased. Further, by covering a part of the outer end surface 10e of the electro-optical panel 10 with the light-shielding adhesive 24, it is possible to improve the light-shielding performance in the vicinity of the adhesion portion.

  Here, the adhesive 24 is usually bonded to a part of the outer end surface 10e adjacent to the bottom surface 10d as shown in the drawing, but as shown by the two-dot chain line in the drawing, the step surface 22 and the outer end surface 10e. It is preferable that the adhesive 24 is adhered to a wider area of the outer end surface 10e by increasing the amount of the adhesive 24 between the two, and of course, the entire outer end surface 10e may be adhered. . Further, if the adhesive 24 is partly adhered to the outer surface of the substrate 12 at the outer peripheral portion of the electro-optical panel 10 from between the step surface 22 and the outer end surface 10e, the adhesive strength and light shielding can be achieved. The sex can be further enhanced. These points are the same in other embodiments described below.

  Further, in the present embodiment, the adhesive 24 is also interposed between the outer end surface 10 e of the electro-optical panel 10 and the step surface 22, whereby the outer peripheral portion of the electro-optical panel 10 is not only the support surface 21 but also the step surface 22. However, since it is adhered, the adhesive strength can be further increased and the light shielding property is further improved.

  However, the step surface 22 is effective in enhancing the positioning and protection of the electro-optical panel 10, but the electro-optical device is provided depending on the thickness of the outer peripheral frame portion on the outer peripheral side by providing the step surface 22. Therefore, it is possible to reduce the size by configuring the outer edge of the support surface 21 as it is as the outer edge of the frame body 20 without providing the stepped surface 22 intentionally. Even in this case, as long as the adhesive 24 is bonded to the outer end surface 10e of the electro-optical panel 10 as described above, the above basic effect itself is not lost.

  Furthermore, since the double-sided pressure-sensitive adhesive tape is not used in this embodiment, even if the width Wd of the support surface 21 is reduced, the double-sided adhesive tape is not easily bonded, and the production efficiency is not reduced. Since the difficulty of punching when processing the adhesive tape into a narrow width does not matter, the manufacturing cost can be reduced.

  The electro-optical device according to this embodiment is manufactured as follows. That is, first, the uncured adhesive 24 is applied to at least one of the bottom surface 10d and the outer end surface 10e of the outer peripheral portion of the electro-optical panel 10 or at least one of the support surface 21 and the step surface 22 of the frame 20 ( First step). Here, examples of the coating method include coating by a printing method such as coating by a dispenser, screen printing, flexographic printing, and the like.

  Next, the outer periphery of the electro-optical panel 10 is disposed on the support surface 21 of the frame 20, and the adhesive 24 is disposed between the outer periphery of the electro-optical panel and the support surface 21 and the step surface 22 of the frame 20. In this manner, the bottom surface 10d and the outer end surface 10e of the outer peripheral portion of the electro-optical panel 10 are bonded to the support surface 21 and the step surface 22 of the frame body 20 by the curing of the adhesive 24 (second step). In this case, in the stage before the adhesive 24 is cured in the second step, when the viscosity of the uncured adhesive 24 is low, the adhesive is interposed between the outer peripheral portion of the electro-optical panel 10 and the support surface 21 by capillary action. When the adhesive 24 penetrates and the viscosity of the uncured adhesive 24 is high, the adhesive 24 spreads between the outer peripheral portion of the electro-optical panel 10 and the support surface 21 by pressurization by the outer peripheral portion of the electro-optical panel 10.

[Second Embodiment]
Next, a second embodiment according to the present invention will be described with reference to FIG. FIG. 3 is an enlarged partial sectional view. In this embodiment, the same parts as those in FIGS. 1 and 14 are denoted by the same reference numerals, and the description thereof is omitted.

  In the present embodiment, as shown in FIG. 3, a double-sided adhesive tape 23 is disposed between the bottom surface 10 d of the outer peripheral portion of the electro-optical panel 10 and the support surface 21 of the frame body 20, and the outer periphery of the double-sided adhesive tape 23. On the side, the same light-shielding adhesive 24 as in the first embodiment is disposed. This adhesive 24 is the same as that of the first embodiment in that it is interposed between the outer peripheral portion of the electro-optical panel 10 and the support surface 21 to bond them together. In the illustrated example, the adhesive 24 is similar to the first embodiment in that the adhesive 24 is interposed between the outer end surface 10e and the stepped surface 22 to bond them together.

  In this case, the double-sided pressure-sensitive adhesive tape 23 is preferably bonded only to the inner peripheral side portion of the support surface 21 as shown in the drawing, and the bottom surface 10 d of the electro-optical panel 10 is attached to the outer peripheral side of the double-sided pressure-sensitive adhesive tape 23. It arrange | positions so that the area | region facing the support surface 21 may remain. With this configuration, the adhesive strength between the outer peripheral portion of the electro-optical panel 10 and the support surface 21 by the adhesive 24 can be increased. Further, although it is difficult to manufacture the double-sided pressure-sensitive adhesive tape 23 itself, the tape width Wt can be made somewhat smaller than the width Wd of the support surface 21, so that the work of attaching the double-sided pressure-sensitive adhesive tape 23 to the support surface 21 can be facilitated. .

  In the illustrated example, the adhesive 24 bonds the outer peripheral portion of the electro-optical panel 10 and the support surface 21, but the double-sided adhesive tape 23 is installed wide so as to protrude from the outer end surface 10 e to the outer peripheral side. The adhesive 24 may be configured to adhere the outer peripheral portion of the electro-optical panel 10 and the double-sided pressure-sensitive adhesive tape 23. In this case, the adhesive 24 is bonded only to the outer end surface 10 e of the outer peripheral portion of the electro-optical panel 10.

  In the present embodiment, the outer peripheral portion of the electro-optical panel and the support surface 21 are bonded by the double-sided adhesive tape 23 on the inner peripheral side and are bonded by the adhesive 24 on the outer peripheral side, so that the bonding area can be secured. Adhesive strength can be increased. Moreover, since the double-sided pressure-sensitive adhesive tape 23 is disposed on the inner peripheral side, it is possible to prevent the adhesive 24 from protruding to the inner peripheral side from the support surface 21 and shielding the display area 10A and a part of the illumination range. . Further, since the adhesive 24 may be applied to the outer end face 10e side of the electro-optical panel 10 after being fixed with the double-sided adhesive tape 23, there is an advantage that the operation of applying the adhesive 24 is not so difficult.

  The electro-optical device according to this embodiment is manufactured as follows. That is, first, the double-sided adhesive tape 23 is attached to the bottom surface 10d or the support surface 21 of the outer peripheral portion of the electro-optical panel 10 (first step). At this time, the double-sided adhesive tape 23 is usually pasted on the support surface 21 first, but may be pasted on the bottom surface 10d of the outer peripheral portion of the electro-optical panel 10 first. Next, the outer peripheral portion of the electro-optical panel 10 is disposed on the support surface 21 so that the bottom surface 10d of the outer peripheral portion of the electro-optical panel 10 is bonded to the support surface 21 via the double-sided adhesive tape 23 (second). Step). Next, an uncured adhesive 24 is applied between the step surface 22 and the outer end surface 10 e, and the outer periphery of the electro-optical panel 10 is supported on the support surface 21 or the outer peripheral side of the double-sided pressure-sensitive adhesive tape 23 by curing the adhesive. It is made to adhere to the double-sided pressure-sensitive adhesive tape 23 (third step). As this coating method, coating by a dispenser is preferable.

[Third Embodiment]
Next, a third embodiment according to the present invention will be described with reference to FIG. FIG. 4 is an enlarged partial sectional view. In this embodiment, the same parts as those in FIGS. 1 and 14 are denoted by the same reference numerals, and the description thereof is omitted.

  In the present embodiment, as shown in FIG. 4, fine spacers 25 are dispersedly disposed in the adhesive 24, and the spacers 25 are interposed between the bottom surface 10 d of the outer peripheral portion of the electro-optical panel 10 and the support surface 21. ing. The spacer 25 is preferably a spherical one made of a fine resin or the like as shown in the example in order to regulate the distance between the bottom surface 10d and the support surface 21 with high accuracy. It is not limited to this.

  In the present embodiment, the outer peripheral portion of the electro-optical panel 10 is bonded onto the support surface 21 using an adhesive 24 in which a plurality of spacers 25 are dispersedly arranged. Thereby, the spacer 25 is arrange | positioned between the bottom face 10d and the support surface 21, and the thickness of the contact bonding layer between both is controlled by the outer diameter of the spacer 25. As a result, the thickness of the adhesive 24 between the bottom surface 10d of the outer peripheral portion of the electro-optical panel 10 and the support surface 21 is controlled, so that the adhesive strength is stabilized and the amount of the adhesive 24 is specified to some extent in advance. In this case, it is possible to prevent the adhesive 24 from protruding to the inner peripheral side of the support surface 21 and obstructing the display area 10A and the illumination range.

  The spacer 25 may be a sheet like the double-sided pressure-sensitive adhesive tape 23 of the second embodiment, and may not have an adhesive layer on at least one of the front and back sides. Such a sheet-like spacer does not have a direct adhesive action between the electro-optical panel 10 and the frame body 20 like the double-sided pressure-sensitive adhesive tape 23 of the second embodiment, but like the spacer 25 described above, the adhesive 24 If the sheet-like spacer is disposed on the inner peripheral side and the adhesive 24 is disposed only on the outer peripheral side, the adhesive 24 is supported on the support surface as in the second embodiment. It is possible to prevent protrusion to the inner peripheral side than 21.

[Fourth Embodiment]
Next, a fourth embodiment according to the present invention will be described with reference to FIG. FIG. 5 is an enlarged partial sectional view. In this embodiment, the same parts as those in FIGS. 1 and 14 are denoted by the same reference numerals, and the description thereof is omitted.

  In the present embodiment, as shown in FIG. 5, the support surface 21 is inclined in the direction away from the electro-optical panel 10 (downward in the drawing) toward the outer peripheral side. As a result, when the outer peripheral portion of the electro-optical panel 10 is disposed on the support surface 21, the adhesive 24 tends to be biased toward the outer peripheral side due to its own weight, so that even if the amount of the adhesive 24 is somewhat excessive, the inner peripheral side. It is prevented from protruding.

[Fifth Embodiment]
Next, a fifth embodiment according to the present invention will be described with reference to FIGS. 6 is an enlarged partial cross-sectional view, and FIG. 7 is a partial plan view (a) to (d) in the vicinity of the support surface. In this embodiment, the same parts as those in FIGS. 1 and 14 are denoted by the same reference numerals, and the description thereof is omitted.

  In the present embodiment, as shown in FIG. 6, a concave groove 26 that is a concave portion is formed in a part of the support surface 21, and a part of the adhesive 24 enters the concave groove 26. Ten outer peripheral portions are bonded and fixed on the support surface 21. By providing the concave groove 26, even if the amount of the adhesive 24 is slightly excessive, a part of the adhesive 24 enters the concave groove 26, so that the spreading range of the adhesive 24 can be controlled. 24 can be prevented from protruding further to the inner peripheral side than the support surface 21 while securing the spread of 24 to the position where the concave groove 26 is formed.

  As shown in FIG. 7A, the concave groove 26 is configured to extend along the extending direction of the support surface 21 formed along the outer periphery of the electro-optical panel 10 in plan view. As a result, the spread range of the adhesive 24 can be controlled more reliably. In other words, the concave groove 26 can align the range of the adhesive 24 on the inner peripheral side in the extending direction of the support surface 21, and the protrusion of the adhesive 24 further to the inner peripheral side can be ensured. Can be prevented. However, the present invention is not limited to such a mode. For example, as long as the concave portion has an arbitrary hole shape such as a circular shape or a polygonal shape in plan view, the concave groove as described above may be used.

  It is preferable that the concave groove 26 and other concave portions provided in the support surface 21 are provided at positions closer to the inner edge portion 21a side than the outer edge portion 21b of the support surface 21 as shown in the illustrated example. In order to prevent the excess adhesive 24 from protruding to the inner peripheral side while securing a certain extent of the adhesive 24 to the inner peripheral side on the support surface 21, a recess is formed on the inner edge 21 a side. This is because it is more effective. However, even if the concave portion is provided on the outer edge portion 21b side, the basic effect is not obtained, and it is effective in preventing the adhesive 24 from protruding to the inner peripheral side with respect to the support surface 21. For example, as indicated by a dotted line in FIG. 6, a recess or a groove may be provided at the boundary position between the support surface 21 and the step surface 22, and further provided in the step surface 22 (lower portion) instead of the support surface 21. May be.

  Further, in the concave groove 26 and other concave portions, it is preferable that the inner side surface 26a on the inner edge portion 21a side is steeper than the inner side surface 26b on the outer edge portion 21b side. This is because if the inner side surface 26a is gentle, the adhesive 24 easily protrudes to the inner peripheral side. If the inner side surface 26a is steep, the adhesive 24 is less likely to protrude inside the inner side surface 26a due to the surface tension and viscosity of the adhesive 24.

  In addition, as shown in FIG.7 (b), it is preferable to provide the inclined guide groove 27 extended from the outer peripheral side of the support surface 21 to the ditch | groove 26 other recesses in the said ditch | groove 26 other recessed part. The inclined guide groove 27 is gradually inclined from the outer peripheral side to the inner peripheral side of the support surface 21 from the surface of the support surface 21 toward the bottom of the concave groove 26 and other concave portions, and the adhesive 24 is allowed to pass through the concave groove 26 and other concave portions. To give priority to. In this case, even when the adhesive 24 is applied to the outer peripheral side of the support surface 21 or the stepped surface 22, the adhesive 24 smoothly flows into the concave groove 26 and other concave portions, and therefore, the gap between the bottom surface 10 d and the support surface 21. Adhesive 24 can be sufficiently disposed on.

  In this case, for example, as shown in FIG. 7C, the adhesive 24 is discretely applied to the upstream end of the inclined guide groove 27 or the outer periphery thereof, and then the outer periphery of the electro-optical panel 10 is placed on the support surface 21. As shown in FIG. 7D, the outer peripheral portion of the electro-optical panel 10 can be bonded and fixed in such a manner that the adhesive 24 preferentially flows into the concave groove 26 as shown by hatching in FIG.

  The manufacturing process of this embodiment is basically the same as that of the first embodiment. However, when the inclined guide groove 27 is provided, the uncured adhesive 24 is on the upstream end of the inclined guide groove 27 on the support surface 21. Alternatively, it is applied to the outer peripheral side.

[Sixth Embodiment]
Next, a sixth embodiment according to the present invention will be described with reference to FIGS. 8 is an enlarged partial sectional view (a) and an enlarged partial plan view (b), and FIG. 9 is an enlarged partial plan view (a) to (d) in the vicinity of the support surface. In this embodiment, the same parts as those in FIGS. 1 and 14 are denoted by the same reference numerals, and the description thereof is omitted.

  In this embodiment, as shown in FIG. 8A, an adhesive 24 is basically disposed in the same manner as in the previous embodiment between the bottom surface 10d of the outer peripheral portion of the electro-optical panel 10 and the support surface 21. However, as shown in FIG. 8B, the inner edge of the adhesive 24 is formed in a meandering shape when viewed in a plan view. That is, the inner edge shape of the adhesive layer on the support surface 21 extending along the outer periphery of the electro-optical panel 10 meanders in the extending direction. Such a meandering shape is obtained by, for example, discretely applying the adhesive 24 in the extending direction on the support surface 21 as shown in FIG. 9A, and then the outer peripheral portion of the electro-optical panel 10 is supported on the support surface. When it is disposed on 21, the adhesive 24 is formed by spreading around the coated area as shown in FIG. 9B.

  In addition, discretely applying the adhesive 24 on the support surface 21 as described above can be easily performed using, for example, a precision dispenser. When the width Wd becomes small, it is extremely effective in controlling the amount of the adhesive 24. The discrete application mode of the adhesive 24 is not limited to the method of periodically applying in the extending direction as described above. For example, the adhesive 24 may be applied in a staggered manner as shown in FIG. Even in this case, when the outer peripheral portion of the electro-optical panel 10 is disposed on the support surface 21 as shown in FIG. 9D, the inner edge of the adhesive 24 is formed in a meandering shape by spreading the adhesive 24.

  In any case, by applying the adhesive 24 discretely as described above, the application work of the adhesive 24 is facilitated, and the amount of the adhesive 24 applied can be easily reduced. It can be prevented from protruding to the circumferential side. In particular, as shown in FIG. 8B, the inner edge of the adhesive 24 is configured in a meandering manner as described above, and the meandering peak portion 24x and valley portion 24y of the inner edge of the adhesive 24 are formed. It means to exist. At this time, even when the amount of the adhesive 24 is somewhat large, when the peak portion 24x reaches the inner edge portion 21a of the support surface 21 first, the protrusion from the inner edge portion 21a to the inner peripheral side is suppressed by the surface tension and viscosity. At the same time, since the valley portion 24y advances toward the inner peripheral side, a large margin of the amount of the adhesive 24 with respect to the protrusion toward the inner peripheral side can be taken.

  Moreover, in the manufacturing method of this embodiment, it can carry out by the step fundamentally similar to 1st Embodiment or 2nd Embodiment. In this case, the application of the adhesive 24 is discrete along the outer periphery of the panel housing portion 20 </ b> A or along the outer periphery of the electro-optical panel 10 with respect to the support surface 21 or the outer peripheral portion of the electro-optical panel 10. To do. In this case, the adhesive 24 can be applied by a dispenser or a printing method. The advantage of this manufacturing method is that the application amount of the adhesive 24 can be reduced by discretely applying the adhesive 24 and can be easily applied even if the width of the support surface 21 is reduced. In addition, the amount of the adhesive 24 can be precisely controlled according to the unit application amount of the discrete application pattern and the application cycle. Such a coating method can also be used in the following seventh embodiment.

[Seventh Embodiment]
Next, a seventh embodiment according to the present invention will be described with reference to FIGS. FIG. 10 is an enlarged partial cross-sectional view when the adhesive 24 is applied, and FIG. 11 is an enlarged partial cross-sectional view in a state where the outer periphery of the electro-optical panel 10 is bonded. In this embodiment, the same parts as those in FIGS. 1 and 14 are denoted by the same reference numerals, and the description thereof is omitted.

  In the present embodiment, as shown in FIG. 10, first, an uncured adhesive 24 is applied on the step surface 22 (first step). In the present invention, the adhesive 24 may be applied to the outer peripheral portion (the bottom surface 10d or the outer end surface 10e) of the electro-optical panel 10 as in the manufacturing process described in the first embodiment, or on the support surface 21. However, in the present embodiment, by applying on the stepped surface 22, the protrusion of the adhesive 24 toward the inner peripheral side of the support surface 21 is suppressed. Here, when the outer peripheral part of the electro-optical panel 10 is arranged on the support surface 21, the adhesive 24 is arranged in a range where a part of the adhesive 24 comes into contact with the outer peripheral part or is caught.

  Next, as shown in FIG. 11, when the outer peripheral portion of the electro-optical panel 10 is disposed on the support surface 21, the adhesive 24 disposed on the outer peripheral side comes into contact with or is caught in the outer peripheral portion of the electro-optical panel 10. As a result, a part of the adhesive 24 is disposed between the bottom surface 10d and the support surface 21, and the adhesive 24 is cured, whereby the electro-optical panel 10 is bonded to the frame body 20 (second step). Here, when the viscosity of the adhesive 24 is low, it only enters the outer peripheral portion of the electro-optical panel 10 and enters between the bottom surface 10d and the support surface 21 by capillary action. When the viscosity is high, the electro-optical panel 10 Is spread between the bottom surface 10d and the support surface 21. In this case, since the main part of the adhesive 24 remains between the outer end surface 10e of the electro-optical panel 10 and the step surface 22, it is possible to suppress the adhesive 24 from protruding further to the inner peripheral side than the support surface 21.

  As described in the sixth embodiment, the method of the present embodiment can also be performed in such a manner that the adhesive 24 is discretely applied to the step surface 22 along the outer periphery. In this case, in addition to the above-mentioned advantages, it is possible to enjoy the advantages of the manufacturing method described in the sixth embodiment.
