Description

  The present invention relates to a structure of an electro-optical device including a display body such as a liquid crystal device.

  A protective member (protective member) is installed on the front side of a display body such as a liquid crystal device. In Patent Document 1, as shown in FIG. 19, a protection member 92 positioned on the front surface side of the display body 90 is fitted so that a step 94 on the front surface side of the protection member 92 and a frame-shaped housing 96 are fitted. A technique for fixing is disclosed. For example, etching is used to form the step 94 of the protection member 92. According to the structure of FIG. 19, the peripheral portion (thin portion) of the protection member 92 is located on the back side of the housing 96 (movement of the protection member 92 to the front side is restricted). The possibility of dropping to the front side together with the protection member 92 is reduced.

JP 2007-114737 A

  However, in the structure of FIG. 19, it is necessary to form the step 94 on the protection member 92, and thus there is a problem that it is difficult to sufficiently secure the mechanical strength of the protection member 92. In order to solve the above problems, a structure that prevents the display body 90 from falling off by a method other than the step of the protective member 92 is required. In view of the above circumstances, an object of the present invention is to effectively reduce the possibility of a display body falling off a casing.

  In order to solve the above-described problems, an electro-optical device according to the present invention includes a display body having a display region in which a plurality of electro-optical elements are arranged in a planar shape, and a surface on the first side (for example, the back side). , A first side surface portion (for example, a side surface portion 46) that faces the side surface of the display body and supports the display body, and an overhang portion that projects to the side of the display body in plan view. A frame including a support portion and a holding portion in which an opening corresponding to the display area of the display body is formed and a surface of a second side (for example, the front side) opposite to the first side of the projecting portion is fixed. A member. The electro-optical device of the present invention can be used in various electronic devices (for example, portable communication terminals).

  In the above configuration, the surface on the first side of the main body portion of the support member faces the display body, and the surface on the second side of the overhanging portion is fixed to the holding portion of the frame-shaped member. That is, the movement of the display body to the second side is restricted by the support member, and the movement of the support member to the second side is restricted by the frame-like member. Therefore, it is possible to effectively reduce the possibility of the display body falling off from the frame-shaped member (housing) to the second side.

  Assumes a Z direction perpendicular to the surface (main surface or plate surface) of a plate-like or layer-like element constituting the electro-optical device (this may also be referred to as a direction perpendicular to the arrangement surface (display surface) of a plurality of electro-optic elements). When viewed from an arbitrary point in the electro-optical device, one side along the Z direction corresponds to the first side, and the other side along the Z direction corresponds to the second side. For example, assuming an observer who visually recognizes a display image of the electro-optical device, the observer side (front side) corresponds to the second side (that is, the front side for the observer) when viewed from an arbitrary point in the electro-optical device. The opposite side (back side) to the observer side corresponds to the first side (that is, the back side for the observer). In addition, in this specification, two elements are “facing” when they face each other (when directly facing each other) with no other element interposed therebetween, and other elements between the two. It also includes the case where they face each other with an intervening state (a case where they face each other indirectly).

  The electro-optical device according to a preferred aspect of the present invention includes a light-transmitting protective member that is fixed to the opposite side of the display member with respect to the support member and is disposed inside the opening of the frame-shaped member. According to the electro-optical device of the present invention, since the display member is prevented from falling off by using the support member, the configuration (step difference of the protective member) of Patent Document 1 that prevents the display body from falling off using the protective member is as follows. It is unnecessary. Therefore, a light-transmitting plate material having a uniform thickness over the entire surface can be used as a protective member. Further, according to the configuration in which the second-side surface of the frame-shaped member and the second-side surface of the protective member are positioned in the same plane, there is a step between the surface of the frame-shaped member and the surface of the protective member. It is possible to improve the designability (aesthetic appearance) as compared to the formed structure.

  An electro-optical device according to a preferred example of a configuration including a protection member includes a planar detection body that detects the approach of an object to be detected, and the detection body is fixed to a surface on the second side of the main body portion and is protected. The member is fixed to the second surface of the detection body. According to the above configuration, the detection body is protected by the protection member. In addition, since the detection body is fixed to the second surface of the main body of the support member and the protection member is fixed to the second surface of the detection body, the detection body and the protection member can be effectively prevented from falling off. There is an advantage.

  Although the form of the support member is arbitrary, for example, a configuration in which an overhang portion is formed so as to protrude from each of the opposing edges of the main body portion (for example, the first embodiment described later), or from the entire periphery of the main body portion A configuration in which an overhang portion is formed so as to overhang (for example, a second embodiment described later) may be employed. According to the former configuration, the support member can be reduced in size as compared with the latter configuration, and according to the latter configuration, the support member and the frame-shaped member can be firmly fixed as compared with the former configuration. Is possible. In any configuration, the position of the overhanging portion is arbitrary. That is, in addition to the configuration in which the overhanging portion is provided continuously with the main body portion and overhanging from the peripheral edge of the main body portion, the overhanging portion is provided continuously with the first side surface portion and is extended from the peripheral edge of the main body portion in plan view. The configuration to be issued (for example, the configuration of FIG. 14) is also included.

  In a preferred example in each of the above aspects, the support member includes a second side surface portion (for example, the side surface portion 48) that protrudes from the periphery of the overhang portion to the first side, and the outer peripheral surface of the second side surface portion is a frame-shaped member. Fixed. In the above aspect, since the second side surface portion is also fixed to the frame-shaped member in addition to the protruding portion, the support member and the frame-shaped member are compared with the configuration in which only the protruding portion is fixed to the frame-shaped member. Can be firmly fixed.

  In a preferred aspect of the present invention, the overhanging portion is formed so as to overhang from the edge of the main body and faces the first end of the protection member, and the frame-like member protrudes from the inner peripheral surface of the opening. And a protruding portion sandwiched between the overhanging portion and the first end portion of the protective member, and a step portion formed on the opposite side of the protruding portion, and being opposite to the first end portion of the protective member The second end portion located on the side is fixed to the step portion of the frame-shaped member. In the above-described configuration, the protrusion is prevented from moving to the second side on the first end side of the protection member, and the second end side of the protection member is the second end. Since the portion is fixed to the frame-like member, movement to the second side is prevented. In addition, the specific example of the above aspect is later mentioned, for example as 3rd Embodiment.

  An electro-optical device according to a preferred aspect of the present invention includes a wiring substrate (for example, a flexible wiring substrate) whose end is fixed to a display body, and the main body portion is a portion where the first side surface portion is formed. And a portion where the first side surface portion is not formed, and the overhang portion is formed in a portion of the edge of the main body portion where the first side surface portion is not formed, and the wiring board is on the first side when viewed from the overhang portion. To position. In the above aspect, since the wiring board is located in the first space as viewed from the overhanging portion, there is an advantage that it is not necessary to excessively deform the wiring board.

  In a preferred aspect of the present invention, the support member includes a claw portion formed on the periphery of the overhang portion and fixed to the frame member. In the above aspect, since the claw portion is also fixed to the frame-shaped member in addition to the fixing of the overhang portion and the frame-shaped member, the support member and the frame-shaped member are compared with the configuration in which the claw portion is not formed. It can be firmly fixed.

The positive side in the Z direction as viewed from an arbitrary position inside the electro-optical device 100A corresponds to the front side (the front side for the user viewing the display image of the electro-optical device 100A), and the negative side in the Z direction as viewed from the position. It corresponds to the side (the back side for the user).

  FIG. 2 is a cross-sectional view of the display assembly 20 and the container 30 assembled (a cross section taken along line VV in FIG. 1). The display assembly 20 in FIG. 1 includes a display body 22, an illuminating body 24, and a holding frame 26 as shown in FIG. The display body 22 is a liquid crystal panel having a structure in which liquid crystal (not shown) is sealed in a gap between the first substrate 221 and the second substrate 223 joined in a state of being opposed to each other. As shown in FIG. 1, a plurality of liquid crystal elements (pixels) PIX in which liquid crystal is interposed between electrodes are arranged in a matrix in the display region D over the X direction and the Y direction. As shown in FIG. 2, a polarizing plate 225 is attached to the front side of the first substrate 221, and a polarizing plate 227 is attached to the back side of the second substrate 223. In addition, a flexible wiring substrate 23 that transmits a control signal for each liquid crystal element PIX is fixed to the second substrate 223.

  The illumination body 24 is a flat surface light source (backlight) disposed on the back side of the display body 22. For example, the illuminating body 24 includes an optical element (not shown) that guides light emitted from the light source to the entire surface of the second substrate 223 (not shown). The holding frame 26 is a rectangular frame made of, for example, a light-reflective resin material, and accommodates and holds the display body 22 and the lighting body 24 in a stacked state.

  As shown in FIGS. 1 and 2, the display assembly 20 is accommodated in a space inside the accommodating body 30 configured by the accommodating member 32 and the support member 40 </ b> A. The housing member 32 includes a rectangular frame-shaped side surface portion 322 and a bottom surface portion 324 on the back side of the side surface portion 322, and houses and holds the display assembly 20. In a state where the display assembly 20 is housed in the housing member 32, the inner peripheral surface of the side surface portion 322 of the housing member 32 and the outer peripheral surface of the holding frame 26 of the display assembly 20 face each other and contact each other. The housing member 32 can be formed by, for example, drawing a metal plate or injection molding a resin material.

  The support member 40 </ b> A in FIG. 1 is a frame (frame) that fixes the display assembly 20 (display body 22) to the housing 10. FIG. 3 is a plan view of the support member 40A as seen from the front side and the back side. A sectional view taken along the line a1-a1 and a sectional view taken along the line a2-a2 in the plan view seen from the front side are also shown in FIG. As shown in FIG. 3, the support member 40 </ b> A is a component in which a main body portion 42, two overhang portions 44, a side surface portion 46, and a side surface portion 48 are integrally formed.

  The main body 42 is a rectangular frame-like portion in which a rectangular opening 41 corresponding to the display area D is formed. Each overhanging portion 44 is a portion overhanging from the outer peripheral edge of the main body portion 42 in a plan view (that is, viewed from the positive side in the Z direction). That is, one overhanging portion 44 overhangs from a part of the edge (long side) located on the positive side in the X direction on the outer peripheral edge of the main body portion 42 to the positive side in the X direction, and the other overhanging portion 44 is From the outer peripheral edge of the main body portion 42, a portion of the edge on the opposite side to the one overhanging portion 44 projects from the negative side in the X direction. The side surface portion 46 and the side surface portion 48 constitute the side surface of the support member 40A. The side surface portion 46 protrudes from the outer peripheral edge of the main body portion 42 (excluding the section where the overhang portion 44 is formed) to the back surface side, and the side surface portion 48 protrudes from the peripheral edge of the overhang portion 44 to the back surface side. The support member 40A having the above shape can be formed by, for example, drawing a metal plate or injection molding a resin material, like the housing member 32.

  In the plan view of FIG. 3, the outer shape of the display assembly 20 (wiring board 23) supported by the support member 40A is shown by a chain line. As can be understood from FIGS. 2 and 3, the housing member 32 that houses the display assembly 20 is fitted into the side surface 46 of the support member 40 </ b> A. Specifically, the protrusion 326 (FIG. 1) formed on the outer peripheral surface of the side surface portion 322 is engaged with an engagement hole (not shown) formed on the inner peripheral surface of the side surface portion 46 of the support member 40A. The support member 40A and the accommodation member 32 are fixed to each other. The outer peripheral surface of the side surface portion 322 of the housing member 32 and the inner peripheral surface of the side surface portion 46 of the support member 40A face each other and come into contact with each other, so that the display assembly 20 in the housing member 32 is within the XY plane. A position is defined.

  As described above, in the state where the display assembly 20 is housed in the housing body 30 constituted by the housing member 32 and the support member 40A, as shown in FIG. 2, the back surface side of the main body 42 in the support member 40A. The front surface and the outer peripheral portion of the display area D of the front-side surface (the surface of the polarizing plate 225) of the display body 22 face each other and are bonded by the adhesive layer L1. That is, the display assembly 20 is fixed to the support member 40A in a state where the main body portion 42 of the support member 40A is positioned on the front side of the display body 22. The adhesive layer L1 is, for example, a double-sided tape.

  In the state where the display assembly 20 is supported by the support member 40 </ b> A, the overhanging portion 44 of the support member 40 </ b> A is provided on the side surface of the display body 22 (or the outer peripheral surface of the holding frame 26 or the side surface portion 322 of the housing member 32). Projects from the outer peripheral surface) to the side opposite to the display body 22. Therefore, as shown in FIG. 2, the inner peripheral surface of the side surface portion 48 of the support member 40 </ b> A and the outer peripheral surface of the side surface portion 322 of the housing member 32 face each other with a space therebetween. As can be understood from FIGS. 2 and 3, the wiring substrate 23 bonded to the second substrate 223 of the display body 22 has the side surface portion 48 through the gap between the holding frame 26 of the display assembly 20 and the support member 40 </ b> A. And the side surface portion 322 are bent so as to reach the space (the space on the back side of the overhang portion 44).

  4 is a cross-sectional view (cross section taken along line VV in FIG. 1) of the display module M (a structure in which the detection body 60 and the protection member 64 are added to the elements in FIG. 2). The detection body 60 is a flat plate type sensor that detects the approach of an object to be detected. Although the detection method of the detection object is arbitrary, for example, a capacitance method is preferably employed. That is, the detection body 60 includes a light-transmitting substrate having a plurality of electrodes (not shown) formed on the front surface. The presence / absence or position of the detection object is determined by detecting the change in capacitance of each electrode according to the presence / absence of the detection object (contact / non-contact with the protective member 64).

  As shown in FIG. 4, the detection body 60 is fixed to the front side of the support member 40A. Specifically, as shown in FIG. 4, the front surface of the main body 42 of the support member 40A and the peripheral surface of the back surface of the detection body 60 face each other and the adhesive layer L2 (for example, both surfaces) Tape). That is, the main body 42 of the support member 40 </ b> A is interposed between the display body 22 and the detection body 60. Therefore, a gap corresponding to the opening 41 of the support member 40A is formed between the front surface of the display body 22 and the back surface of the detection body 60.

  4 is a light-transmitting plate member that protects the detection body 60 and the display body 22, and is formed to have a uniform thickness over the entire surface. For example, a glass substrate or a resin substrate (for example, an acrylic plate) is preferably used as the protective member 64. The protection member 64 is bonded to the front surface of the detection body 60 using a light-transmitting adhesive layer 62 (for example, a light-transmitting resin material). As can be understood from FIG. 4, in a state where the protection member 64 is fixed, the side surface of the display assembly 20 (the outer peripheral surface of the holding frame 26) is located on the inner side of the periphery of the protection member 64 in the plan view. Each overhanging portion 44 of the member 40 </ b> A is located outside the peripheral edge of the protection member 64.

  FIG. 5 is a cross-sectional view (cross section taken along line VV in FIG. 1) in which the frame-like member 12A of the housing 10 is added to the elements of FIG. 4, and FIG. 6 shows the frame-like member 12A and the support member. It is a disassembled perspective view at the time of seeing 40A from the back side. As shown in FIGS. 5 and 6, the frame-shaped member 12 </ b> A is a rectangular frame in which an opening 13 corresponding to the display area D of the display body 22 is formed. A stepped portion 16 (notch) that accommodates and supports each overhanging portion 44 of the support member 40A is formed on the periphery of the opening 13 in the surface on the back side of the frame-shaped member 12A. The step portion 16 is formed in a groove shape including a bottom surface (hereinafter referred to as “holding portion”) 162 facing the back surface side and a side surface 164 extending from the holding portion 162 to the back surface side.

  As shown in FIG. 6, each overhanging portion 44 of the support member 40 </ b> A is accommodated inside the stepped portion 16. In a state where each overhanging portion 44 is accommodated in the stepped portion 16, as shown in FIG. 5, the surface on the front surface side of the overhanging portion 44 and the holding portion 162 (the surface on the back surface side of the frame-shaped member 12A) are mutually connected. The outer peripheral surface of the side surface portion 48 of the support member 40A and the side surface 164 of the stepped portion 16 are opposed to each other and bonded by the adhesive layer L4. The display assembly 20 supported by the support member 40A is fixed to the frame member 12A by joining the support member 40A and the frame member 12A to the above state.

  As shown in FIG. 5, in a state where the support member 40A is fixed to the frame-shaped member 12A, the protective member 64 fixed to the support member 40A via the detection body 60 is located inside the opening 13 of the frame-shaped member 12A. Placed in. The size and shape of the opening 13 of the frame-shaped member 12A are selected so that the side surface of the protection member 64 and the inner peripheral surface of the opening 13 are in close contact with each other (contact with no gap). When the support member 40A is fixed to the frame member 12A, the front surface of the protection member 64 and the front surface of the frame member 12A are in the same plane (a parallel plane P with the XY plane). In). Therefore, the design (aesthetic appearance) is improved as compared with the configuration in which there is a step between the protective member 64 and the frame-shaped member 12A. Since the protective member 64 is fixed to the support member 40A, it is not necessary to directly bond the protective member 64 to the frame-shaped member 12A, but the protective member 64 is frame-shaped from the viewpoint of ensuring mechanical strength. A configuration of joining (for example, bonding) to the member 12A can also be adopted.

  The assembly of the electro-optical device 100A described above is performed, for example, according to the following procedure. First, the housing member 32 in which the display assembly 20 is housed is fitted into the side surface 46 of the support member 40A, and the front surface of the display body 22 is covered with the adhesive layer L1 of the main body 42 of the support member 40A. Join to the back side. Second, the display module M is created by sequentially fixing the detection body 60 and the protection member 64 to the front side of the main body 42 of the support member 40A. Third, the display module M is fitted to the frame-shaped member 12A from the back side, and the overhanging portion 44 and the side surface portion 48 of the support member 40A are joined into the stepped portion 16 of the frame-shaped member 12A. Finally, the back member 14 is fixed to the frame-like member 12A, thereby completing the electro-optical device 100A.

  In the above embodiment, the surface on the front side of the display body 22 faces and contacts the surface on the back side of the main body 42 of the support member 40A and the surface on the back side of the frame-shaped member 12A of the housing 10 (the holding portion 162). ) Is opposed to the front surface of the overhanging portion 44 of the support member 40A. That is, the movement of the display body 22 to the front side is restricted by the support member 40A, and the movement of the support member 40A to the front side is restricted by the frame-like member 12A. Therefore, in spite of a configuration in which the step that fits into the housing 10 is not formed in the protective member 64 (that is, a configuration in which insufficient strength of the protective member 64 due to the formation of the step is suppressed), the display body 22 is provided in the housing. The possibility of dropping to the front side with respect to 10 (frame-like member 12A) can be effectively reduced. In addition to the overhanging portion 44 of the support member 40A, the side surface portion 48 is also joined to the frame-like member 12A of the housing 10, so that only the overhanging portion 44 is joined to the frame-like member 12A. Compared to the omitted configuration, there is an advantage that the support member 40A (and the display body 22) is firmly fixed to the frame-shaped member 12A.

  In addition, since the detection body 60 is fixed to the support member 40A that supports the display body 22, the detection body 60 is detected due to the contact of the detection object as compared with the configuration in which the detection body 60 is directly joined to the surface of the display body 22. When the body 60 is deformed, the propagation of stress from the detection body 60 to the display body 22 can be suppressed. Therefore, there is an advantage that display defects and breakage of the display body 22 due to external force can be effectively prevented.

  Since the wiring board 23 mounted on the display body 22 is bent so as to pass through the space on the back side of the overhanging portion 44, for example, the side surface portion 322 of the housing member 32 and the side surface portion 46 of the supporting member 40A As compared with the configuration in which the wiring board 23 is forcibly bent so as to pass between the two, the excessive deformation of the wiring board 23 is suppressed (therefore, the possibility of breakage of the wiring board 23 and disconnection of the wiring is reduced). ).

<B: Second Embodiment>
Next, a second embodiment of the present invention will be described. In the following examples, elements having the same functions and functions as those of the first embodiment are denoted by the same reference numerals, and detailed descriptions thereof are omitted as appropriate.

  The electro-optical device 100B of the second embodiment has a configuration in which the support member 40A of the first embodiment is replaced with a support member 40B, and the frame-shaped member 12A of the first embodiment is replaced with a frame-shaped member 12B. FIG. 7 is a plan view of the support member 40B in the second embodiment as seen from the front side and the back side. FIG. 7 also shows a cross-sectional view taken along the line bb in the plan view on the front side. FIG. 8 is an exploded perspective view when the frame-like member 12B and the support member 40B are viewed from the back side.

  In the support member 40 </ b> A of the first embodiment, an overhang portion 44 is formed on a part of the periphery of the main body portion 42. As shown in FIG. 7, the support member 40 </ b> B of the second embodiment is formed with an overhang portion 44 over the entire circumference of the main body portion 42. That is, the overhanging portion 44 of the support member 40B is a rectangular frame-shaped portion that surrounds the main body portion 42 in plan view. The side surface portion 46 is formed in a rectangular frame shape along the outer peripheral edge of the main body portion 42, and the side surface portion 48 is formed in a rectangular frame shape along the outer peripheral edge of the overhang portion 44. Accordingly, the side surface portion 48 surrounds the side surface portion 46 with the outer peripheral surface of the side surface portion 46 and the inner peripheral surface of the side surface portion 48 facing each other with a space therebetween. The display assembly 20 is fitted into the side surface portion 46 with the entire periphery surrounded by the side surface portion 46. In addition, claw portions 52 that protrude from the side surface portion 48 in the Y direction (direction parallel to the surface of the protection member 64) are formed at portions of the side surface portion 48 that correspond to the four corners of the support member 40B.

  As shown in FIG. 8, the stepped portion 16 formed by the holding portion 162 (bottom surface) and the side surface 164 is formed over the entire periphery of the opening portion 13 on the rear surface of the frame-shaped member 12B. Similarly to the first embodiment, the support member 40B is fixed to the frame-shaped member 12B in a state where the overhanging portion 44 of the support member 40B is accommodated inside the stepped portion 16. That is, as in the example of FIG. 5, the surface on the front side of the overhanging portion 44 and the holding portion 162 (the bottom surface of the stepped portion 16) face each other and are bonded by the adhesive layer L 3, and The outer peripheral surface and the side surface 164 of the stepped portion 16 face each other and are joined by the adhesive layer L4. Further, as can be understood from FIG. 8, each claw portion 52 of the support member 40B is fixed to the frame-shaped member 12B using, for example, a screw. Other configurations are the same as those of the first embodiment.

  In the second embodiment, the same effect as in the first embodiment is realized.
