  The present invention relates to an electro-optical device, a protection member, and an electronic apparatus.

  In recent years, portable information communication devices such as mobile phones, pagers, PDAs, and notebook personal computers have been widely used. Also, electro-optical devices such as liquid crystal display devices are often used as display devices in such devices.

In portable information communication devices, as a requirement for portability, it is particularly strongly required to have impact resistance while being small and light. In a portable information communication device, one of the parts that is usually most susceptible to impact is an electro-optical device. Therefore, in order to improve the impact resistance of the electro-optical device, for example, Patent Document 1 discloses a technique for providing a protection member for the electro-optical device.

  However, in order to give a partial light-shielding property or decorative property to the display of the electro-optical device, for example, a protective member having a configuration in which colored printing is applied to a translucent substrate may be used. When such a protective member is used, a step is generated in the printing portion, and bubbles may be mixed into the adhesive interface when the protective member and the electro-optical device are attached. If bubbles are mixed in this way, display defects may occur or problems such as poor adhesion may occur.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a highly reliable electro-optical device that is excellent in impact resistance and the like and hardly causes display defects.

A protective member for protecting the electro-optical panel, the protective member comprising a light-transmitting substrate and a light-shielding member embedded in a recess formed in the light-transmitting substrate. It is characterized by.

  According to such an electro-optical device, it becomes possible to provide impact resistance to the electro-optical panel in the electro-optical device by the protective member, and to the electro-optical device by the light shielding member provided in the protective member. A light-blocking property or a decorative property (decoration with a predetermined light-blocking pattern) can be imparted, and since the light-shielding member is disposed in a recess provided in the light-transmitting substrate, a step due to the provision of the light-shielding member is formed. It will be difficult. That is, the thickness of the light shielding member can be offset by the depth of the recess, and if the thickness and the depth are designed to be the same value, the surface of the translucent substrate and the surface of the light shielding member are designed to be flush with each other. It becomes possible. As a result, even when the protective member is attached to the electro-optical panel by adhesion or the like, bubbles or the like are mixed into the attachment interface (adhesion interface) to cause a display failure or a decrease in attachment force (adhesion force). This makes it possible to provide a highly reliable electro-optical device.

  In order to solve the above problems, as a second aspect of the electro-optical device of the present invention, an electro-optical panel having an electro-optical layer between a pair of substrates and at least one of the substrates And a protection member that protects the electro-optic panel, and the protection member is surrounded by the light-transmitting substrate, a light-shielding member having a predetermined pattern formed on the light-transmitting substrate, and the light-shielding member. And a translucent member.

  According to such an electro-optical device, it becomes possible to provide impact resistance to the electro-optical panel in the electro-optical device by the protective member, and to the electro-optical device by the light shielding member provided in the protective member.

That is, the thickness of the light shielding member can be offset by the thickness of the translucent member. If the thicknesses of both members are designed to be the same value, the surface of the protective member can be designed to be flush with each other. It is. As a result, even when the protective member is attached to the electro-optical panel by adhesion or the like, bubbles or the like are mixed into the attachment interface (adhesion interface) to cause a display failure or a decrease in attachment force (adhesion force). This makes it possible to provide a highly reliable electro-optical device.

In other words, the thickness of the light shielding member can be offset by the thickness of the translucent member, and if the thickness of both members is designed to be the same value, the surface can be designed to be flush with the surface. Since the planarization layer is formed even if it is not one, the flatness of the surface of the said protection member becomes a very high thing. As a result, even when the protective member is attached to the electro-optical panel by adhesion or the like, bubbles or the like are mixed into the attachment interface (adhesion interface) to cause a display failure or a decrease in attachment force (adhesion force). This makes it possible to provide a highly reliable electro-optical device.

  The light shielding member referred to in the present invention includes not only a member that completely shields light (display) from the electro-optical device but also a semi-shielding member that partially shields light.

That is, the thickness of the light shielding member can be offset by the depth of the recess, and if the thickness and the depth are designed to be the same value, the surface of the translucent substrate and the surface of the light shielding member are designed to be flush with each other. It becomes possible. As a result, even when the protective member is attached to the electro-optical panel by adhesion or the like, bubbles or the like are mixed into the attachment interface (adhesion interface) to cause a display failure or a decrease in attachment force (adhesion force). Therefore, it is possible to provide a highly reliable electro-optical panel (electro-optical device) with a protective member.

It is difficult to form a step due to the application. That is, the thickness of the light shielding member can be offset by the thickness of the translucent member. If the thicknesses of both members are designed to be the same value, the surface of the protective member can be designed to be flush with each other. It is. As a result, even when the protective member is attached to the electro-optical panel by adhesion or the like, bubbles or the like are mixed into the attachment interface (adhesion interface) to cause a display failure or a decrease in attachment force (adhesion force). Therefore, it is possible to provide a highly reliable electro-optical panel (electro-optical device) with a protective member.

  Next, in order to solve the above-described problem, a third aspect of the protective member of the present invention is a protective member that protects the electro-optical panel, and is formed on the translucent substrate and the translucent substrate.

  Hereinafter, preferred embodiments of the present invention will be described more specifically with reference to the drawings. In addition, in each figure, in order to make each layer and each member the size which can be recognized on drawing, the scale is varied for every layer and each member.

[First Embodiment]
FIG. 1 is a perspective view schematically showing an overall configuration of a mobile phone 10 which is an embodiment of an electronic apparatus of the present invention, and FIG. 2 is a cross-sectional view schematically showing a cross-sectional configuration in the vicinity of a display unit of the mobile phone 10. FIG. 3 is a cross-sectional view schematically showing a cross-sectional configuration of a display device (electro-optical device) provided in the mobile phone 10.

  As shown in FIG. 1, the mobile phone 10 according to the present embodiment includes a plastic housing 14, a display unit 1 that is exposed from the housing 14, an operation unit (operation button) 2, and an antenna 3. Configured. The display unit 1 has a cross-sectional configuration as shown in FIG. 2, and includes a display device (electro-optical device) 1 a that is exposed to the outside from a display window 14 e (see FIG. 1) of the housing 14, and the housing 14. It is mainly composed of a backlight 40 incorporated therein. The backlight 40 is held on the housing 14 via a predetermined circuit board 44.

  In the present embodiment, the display device 1a is composed of a liquid crystal device, and includes a liquid crystal panel (electro-optical panel) 28, a protective member 19, and an adhesive layer 22 that attaches the protective member 19 to the liquid crystal panel 28. Yes. Here, the display device 1 a is attached to the mobile phone 10 in such a manner that the side surface of the protective member 19 is bonded to the housing 14 of the mobile phone 10. For example, as shown in FIG. 7, the stepped portion 14 b is formed in the display window 14 a of the housing 14, while the projecting portion 18 b is formed on the translucent substrate 18 of the protection member 19. It is good also as what attaches the display apparatus 1a to the mobile telephone 10 by the method of fitting with respect to the level | step-difference part 14b of the body 14. FIG.

  As shown in FIG. 3, the liquid crystal panel 28 includes two transparent substrates 30, 30, polarizing plates 31, 31 attached to the respective substrates 30, 30, a sealing material 32 that seals the periphery, A liquid crystal (electro-optic layer) 34 enclosed in a space formed by them is included. The two substrates 30 are each formed of either glass or plastic.

  In terms of the driving method, the liquid crystal panel 28 is a simple matrix liquid crystal display panel or static drive liquid crystal display panel that does not use a switching element for the panel itself, a three-terminal switching element represented by TFT, or two represented by MIM. Various types of liquid crystal panels such as TN type, STN type, guest-host type, phase transition type, and ferroelectric type can be used as active matrix liquid crystal display panels using terminal switching elements.

  On the other hand, the protective member 19 attached to the liquid crystal panel 28 via the adhesive layer 22 is formed of an acrylic resin and sufficiently transmits visible light. For example, the transparent substrate 18 having a thickness of about 1 mm to 2 mm is used. It is configured as a main body and has a strength that can withstand a drop impact when being carried. In the present embodiment, the protection member 19 constitutes a part of the housing 14 of the mobile phone 10.

  The translucent substrate 18 has a stepped portion (recess or groove) 18a formed by cutting out the outer edge of one main surface, and a light shielding member 17 is disposed in the stepped portion 18a. Here, the protective member 19 and the liquid crystal panel 28 are aligned so that the light shielding member 17 disposed in the step portion 18a of the light-transmitting substrate 18 shields part or all of the outer ring of the liquid crystal panel 28. Thus, in the present embodiment, the alignment is performed so as to at least shield the sealing material 32 of the liquid crystal panel 28. That is, the step portion 18 a of the translucent substrate 18 is formed in a pattern that can be aligned along part or all of the outer ring of the liquid crystal panel 28.

  Specifically, as shown in FIG. 6, the alignment is performed at an alignment mark 41 formed at a position overlapping the light shielding member 17 of the protection member 19 and an alignment mark formed at a position overlapping the sealing material 32 of the liquid crystal panel 28. 42 is overlapped. After alignment, the circuit board 12 having the external connection terminals of the liquid crystal panel 28 is exposed to the outside from the protective member 19.

  The depth of the stepped portion 18a is designed according to the thickness of the light shielding member 17, and is designed to be the same depth as the thickness of the light shielding member 17 to be formed here. Specifically, the depth is 0.05 mm to 0.2 mm (for example, 0.1 mm), and the light shielding member 17 is configured to have the same thickness as the depth. As a result, the surfaces of the translucent substrate 18 and the light shielding member 17 are flush with each other, and the interface between the protective member 19 and the adhesive layer 22 is flat. If the depth of the light-shielding member 17 is at least greater than the thickness of the light-shielding member 17, the surface of the translucent substrate 18 occupying most of the main surface of the protective member 19 is in contact with the adhesive layer 22. A mixing prevention effect can be realized. Moreover, although the level | step-difference part 18a is formed in the side groove | channel type | mold in this embodiment, if the recessed part which has predetermined | prescribed depths, such as a moat type | mold, for example, the form will not be specifically limited.

  In addition, although the light shielding member 17 is made of metal chromium, it is also possible to use a metal material such as resin black obtained by dispersing carbon or titanium in a photoresist, or nickel. Alternatively, a two-layer structure of metal chromium and chromium oxide can be adopted for low reflection. In addition, the translucent substrate 18 may be made of urethane resin, epoxy resin, or the like in addition to acrylic resin.

  The adhesive layer 22 that bonds the liquid crystal panel 28 and the protection member 19 is a transparent elastic resin formed over the entire display surface of the liquid crystal panel 28. For example, a silicone resin such as silicon gel, an acrylic resin, a urethane resin, or the like is used. It is a material that has curability and can maintain elasticity after heat curing, and sufficiently transmits visible light, and has a thickness of about 30 μm.

  The transparent elastic resin constituting the adhesive layer 22 has adhesiveness, and can be attached to the polarizing plate 31 of the liquid crystal panel 28 and the translucent substrate 18 of the protective member 19 by the adhesive force. Further, the transparent elastic resin is advantageous in that it can be firmly bonded to the liquid crystal panel 28 and the translucent substrate 18 by thermosetting without using an adhesive. Note that the transparent elastic resin retains a predetermined elasticity even after the thermosetting. Thus, since the transparent elastic resin has adhesiveness, the protective member 19 and the liquid crystal panel 28 can be kept in close contact without using an adhesive or the like.

  According to the mobile phone 10 of the present embodiment as described above, since the display device 1a configuring the display unit 1 is configured by the liquid crystal device in which the surface of the liquid crystal panel 28 is covered with the protective member 19, The liquid crystal panel 28 is excellent in performance, and the liquid crystal panel 28 is unlikely to be damaged by an impact such as dropping.

Further, since the light shielding member 17 is provided to the protection member 19, the outer ring of the liquid crystal panel 28 (near the region where the sealing material 32 is formed) can be shielded appropriately.
In addition, since the light shielding member 17 is disposed in the stepped portion 18 a provided on the translucent substrate 18, it is difficult to form irregularities (steps) on the surface of the protective member 19 due to the provision of the light shielding member 17. Become. Therefore, when the protective member 19 and the liquid crystal panel 28 are bonded to each other, it is difficult to cause a problem that air bubbles or the like are mixed into the adhesive layer 22, and as a result, a problem of causing a display defect or a decrease in adhesive force occurs. It has become difficult.

Hereinafter, a method for manufacturing the display unit 1 of the mobile phone 10 of the present embodiment will be described.
First, the curable resin constituting the adhesive layer 22 is temporarily bonded to the entire display surface of the liquid crystal panel 28, and the entire other surface side of the curable resin is temporarily bonded to the protective member 19. And it confirms that dust etc. do not intervene in each adhesion surface in the state of this temporary adhesion. If dust or the like is present on any bonding surface, the temporary bonding is peeled off, the dust or the like is removed, and then temporarily bonded again. Then, the curable resin is heated and cured with sufficient elasticity to maintain impact resistance, and the curable resin is further firmly bonded to the liquid crystal panel 28 and the protection member 19.

  Here, in this embodiment, although the light shielding member 17 is provided to the protective member 19, since the light shielding member 17 is disposed in the step portion 18a, the adhesive surface of the protective member 19 is flat without unevenness. Therefore, it is extremely difficult for bubbles or the like to be mixed into the adhesive layer 22.

[Second Embodiment]
Hereinafter, modifications of the display device 1a will be described.
FIG. 4 is a diagram schematically showing a cross-sectional configuration of the display device 1b, and corresponds to FIG. 3 of the display device 1a. Here, regarding the display device 1b, the configuration of the protective member 19 is different from the configuration of the display device 1a of FIG. 3, and the adhesive layer 22 and the liquid crystal panel 28 have the same configuration as the display device 1a of FIG. Omitted and only the protective member 19 will be described.

  In the display device 1b, the protective member 19 that protects the liquid crystal panel 28 is made of an acrylic resin and is configured mainly with a transparent substrate 18 that transmits visible light sufficiently and has a thickness of, for example, about 1 mm to 2 mm. It has the strength to withstand drop impacts when carried. The functional layer 15 is formed on the main surface of the translucent substrate 18 that faces the liquid crystal panel 28 (that is, the surface on the adhesive layer 22 side).

  The functional layer 15 includes a light shielding member 17 having a predetermined pattern and a translucent member 16 surrounded by the light shielding member 17. Like the display device 1 a shown in FIG. 3, the light shielding member 17 is a liquid crystal panel 28. The sealing material 32 is at least shielded from light. That is, the light shielding member 17 is arranged in a pattern so that the light shielding member 17 is disposed at a position overlapping with the sealing material 32 of the liquid crystal panel 28 or at a position inside the display material 32 (display area side). Further, the protective member 19 including the light shielding member 17 and the liquid crystal panel 28 are aligned. As a result, the translucent member 16 overlaps the display area of the liquid crystal panel 28 (the inner area of the sealing material 32), and the display information on the liquid crystal panel 28 can be visually recognized through the translucent member 16. . In the present embodiment, the light shielding member 17 is configured to shield the entire outer ring of the liquid crystal panel 28.

  In addition, as shown in FIG. 6, the alignment includes an alignment mark 41 formed at a position overlapping the light shielding member 17 of the protection member 19 and an alignment mark 42 formed at a position overlapping the sealing material 32 of the liquid crystal panel 28. This is done by superimposing. After alignment, the circuit board 12 having the external connection terminals of the liquid crystal panel 28 is exposed to the outside from the protective member 19.

  In the present embodiment, the light shielding member 17 and the light transmitting member 16 are designed to have the same thickness (for example, 10 μm). Therefore, the surface of the functional layer 15 is flush, and as a result, the interface between the protective member 19 and the adhesive layer 22 is flat. Further, although the light shielding member 17 is made of metallic chrome, it is also possible to use a metal material such as resin black obtained by dispersing carbon or titanium in a photoresist, or nickel. Alternatively, a two-layer structure of metal chromium and chromium oxide can be adopted for low reflection. Moreover, the translucent member 16 can also be comprised by urethane resin, an epoxy resin, etc. other than an acrylic resin.

  According to the mobile phone 10 including the display device 1b as described above, the display device 1b that constitutes the display unit 1 is formed of a liquid crystal device in which the surface of the liquid crystal panel 28 is covered with the protective member 19, so It has excellent impact properties, and it is difficult for the liquid crystal panel 28 to be damaged due to an impact such as dropping.

Further, since the light shielding member 17 is provided to the protection member 19, the outer ring of the liquid crystal panel 28 (near the region where the sealing material 32 is formed) can be shielded appropriately.
In addition, since the light shielding member 17 surrounds the light transmitting member 16 and the functional layer 15 composed of the light shielding member 17 and the light transmitting member 16 is flush, the light shielding member 17 is provided. Unevenness (steps) is hardly formed on the surface of the protection member 19. Therefore, when the protective member 19 and the liquid crystal panel 28 are bonded to each other, it is difficult to cause a problem that air bubbles or the like are mixed into the adhesive layer 22, and as a result, a problem of causing a display defect or a decrease in adhesive force occurs. It has become difficult.
In addition, about the manufacturing method of the display part 1 of the mobile telephone 10 provided with the display apparatus 1b, the method similar to 1st Embodiment mentioned above is employable.

Here, regarding the display device 1c, the configuration of the protective member 19 is different from the configuration of the display device 1a of FIG. 3, and the adhesive layer 22 and the liquid crystal panel 28 have the same configuration as the display device 1a of FIG. Omitted and only the protective member 19 will be described.

  In the display device 1c, the protective member 19 that protects the liquid crystal panel 28 is a substrate that is formed of an acrylic resin and sufficiently transmits visible light. For example, the transparent substrate 18 having a thickness of about 1 mm to 2 mm is used. It is configured as a main body and has a strength that can withstand a drop impact when being carried. The functional layer 15 is formed on the main surface of the translucent substrate 18 that faces the liquid crystal panel 28 (that is, the surface on the adhesive layer 22 side).

  The functional layer 15 includes a functional main layer 13 and a planarization layer 14 formed on the functional main layer 13. Here, the functional main layer 13 is a film including a light shielding member 17 having a predetermined pattern and a light transmissive member 16 surrounded by the light shielding member 17, and is similar to the display device 1 a illustrated in FIG. 3. 17 shields at least the sealing material 32 of the liquid crystal panel 28.

  That is, the light shielding member 17 is arranged in a pattern so that the light shielding member 17 is disposed at a position overlapping with the sealing material 32 of the liquid crystal panel 28 or at a position inside the display material 32 (display area side). Further, the protective member 19 including the light shielding member 17 and the liquid crystal panel 28 are aligned. As a result, the translucent member 16 overlaps the display area of the liquid crystal panel 28 (the inner area of the sealing material 32), and the display information on the liquid crystal panel 28 can be visually recognized through the translucent member 16. . In the present embodiment, the light shielding member 17 is configured to shield the entire outer ring of the liquid crystal panel 28.

  In addition, as shown in FIG. 6, the alignment includes an alignment mark 41 formed at a position overlapping the light shielding member 17 of the protection member 19 and an alignment mark 42 formed at a position overlapping the sealing material 32 of the liquid crystal panel 28. This is done by superimposing. After alignment, the circuit board 12 having the external connection terminals of the liquid crystal panel 28 is exposed to the outside from the protective member 19.

  In the present embodiment, the light shielding member 17 and the light transmitting member 16 are designed to have the same thickness (for example, 10 μm). Further, although the light shielding member 17 is made of metallic chrome, it is also possible to use a metal material such as resin black obtained by dispersing carbon or titanium in a photoresist, or nickel. Alternatively, a two-layer structure of metal chromium and chromium oxide can be adopted for low reflection. Moreover, the translucent member 16 can also be comprised by urethane resin, an epoxy resin, etc. other than an acrylic resin.

  According to the mobile phone 10 including the display device 1b as described above, the display device 1b that constitutes the display unit 1 is formed of a liquid crystal device in which the surface of the liquid crystal panel 28 is covered with the protective member 19, so It has excellent impact properties, and it is difficult for the liquid crystal panel 28 to be damaged due to an impact such as dropping.
