Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to an electronic package, a display device and an electronic apparatus. 
       BACKGROUND ART 
       [0002]    Conventionally, in various electronic apparatuses, measures against static electricity are taken. For example, in a liquid crystal display device (display device)  169  as well that is described in a patent document 1 and shown in a perspective view of  FIG. 7 , measures against static electricity are taken. 
         [0003]    In detail, the liquid crystal display device  169  described in the patent document 1, a liquid crystal display panel  159  is sandwiched between an upper metal housing bz 1  and a lower metal housing bz 2 . Besides, in the liquid crystal display panel  159 , an FPC (Flexible Printed Circuits) board  111  that connects a driver (not shown) for driving the liquid crystal and a main board (not shown) to each other is disposed (here, a thing in which the FPC board  111  is disposed in at least one of the metal housings bz 1 , bz 2  is also called an electronic package pg). 
         [0004]    The FPC board  111 , as shown in a plan view of  FIG. 8 , hangs down to cover a side surface of the lower metal housing bz 2  and bends to cover a rear side of a bottom surface  133  of the lower metal housing bz 2 . And, on part of the FPC board  111  that covers the rear side of the bottom surface  133  of the lower metal housing bz 2 , a ground pattern  112  is formed (here, a ground line  191  contained in the FPC board  111  is connected to the ground pattern  112 ). As a result of this, the ground pattern  112  touches the lower metal housing bz 2  that has electrical conductivity. 
         [0005]    According to this, even if static electricity occurs in the liquid crystal display device  169 , the static electricity flows to the lower metal housing bz 2  via the ground pattern  112 . Accordingly, for example, malfunction of various circuits of the liquid crystal display device  169  due to the static electricity do not happen.

       SUMMARY OF INVENTION 
     Technical Problem 
       [0007]    However, in the liquid crystal display device  169 , the ground pattern  112  and the lower metal housing bz 2  are connected to each other via an electro-conductive adhesive (see paragraph [0024] in the patent document 1). Because of this, the cost of the liquid crystal display device  169  inevitably becomes high. 
         [0008]    Besides, in light of cost reduction, it is conceivable to directly connect the ground pattern  112  and the lower metal housing bz 2  to each other without using the electro-conductive adhesive. However, the ground pattern  112  is disposed in the FPC board  111  that flexibility. Because of this, if the FPC board  111  bends and the ground pattern  112  deviates, the ground pattern  112  and the lower meal housing bz 2  are likely to peel off each other (in short, static electricity is unlikely to escape to the lower metal housing bz 2 ). 
         [0009]    The present invention has been made to solve the above problems. And, it is an object to provide an electronic package and the like that surely perform contact between a ground pattern and a member that serves as a conductive portion. 
       Solution to Problem 
       [0010]    In the electronic package, a chassis and a circuit board including a ground pattern are disposed in a housing. In the electronic package, the ground pattern is present between the housing and the chassis. And, the housing includes a push piece that pushes the ground pattern against the chassis; and the push piece has elasticity in a linear state and pushes the ground pattern by means of a tip end whose outer edge is rounded. 
         [0011]    According to this, the ground pattern is sandwiched between the two members (housing and chassis), so that the ground pattern is unlikely to deviate excessively considerably. Moreover, the push piece is formed at one end of the housing; and the push piece, thanks to elasticity of itself, relatively firmly pushes the ground pattern against the chassis. Because of this, without using a separate member like an electro-conductive adhesive, the ground pattern and the housing touch each other and static electricity flows to the housing. 
         [0012]    Besides, the rounded tip end of the push piece touches the ground pattern, so that a sharp member does not touch the ground pattern. Accordingly, the ground pattern is unlikely to be broken. 
         [0013]    Here, the shape of the push piece is not limited to a thing that is a linear piece having elasticity and has a tip end whose outer edge is rounded. For example, the push piece may swell from a surface of the housing and a tip end of the swelling may be formed into a curved surface. And, such a push piece may push the ground pattern by means of the curved-surface tip end. 
         [0014]    Even according to this, the curved-surface tip end of the push piece touches the ground pattern, so that a sharp member does not touch the ground pattern. Accordingly, the ground pattern is unlikely to be broken. 
         [0015]    Here, it is possible to say that a display device incorporating such an electronic package and an electronic apparatus incorporating the display device are the present invention. 
       Advantageous Effects of Invention 
       [0016]    According to the present invention, the contact between the ground pattern and the housing that serves as the conductive portion is surely performed; and static electricity flows to the housing. Accordingly, various disadvantages (e.g., circuit malfunction) due to the static electricity do not happen.

     DESCRIPTION OF EMBODIMENTS  
     Embodiment 1  
       [0029]    An embodiment is described based on drawings as follows. Here, for convenience, hatching, member numbers and the like are omitted in some cases; in this case, other drawings are referred to. Besides, a black dot in a drawing means a direction perpendicular to a paper surface. 
         [0030]    Here, in the following description, as an example of a display device, a liquid crystal display device is described; however, this is not limiting. For example, an organic EL (Electro-Luminescence) display and a plasma display may be used. 
         [0031]    A sectional view of  FIG. 1  and an exploded perspective view of  FIG. 2  show a liquid crystal display device  69  (here, the sectional direction in  FIG. 1  is a direction taken along and viewed from an arrow A-A′ line in  FIG. 2 .) 
         [0032]    As shown in  FIG. 1  and  FIG. 2 , the liquid crystal display device  69  includes: a liquid crystal display panel  59 ; a backlight unit  49 ; and bezels BZ (front bezel and rear bezel) that sandwich and hold the liquid crystal display panel  59  and the backlight unit  49 . 
         [0033]    The liquid crystal display panel  59  attaches an active matrix board  51  that includes switching elements such as a TFT (Thin Film Transistor) and the like, and an opposite board  52  that faces the active matrix board  51  to each other by means of a seal member (not shown). And, liquid crystal (not shown) is injected into a gap between both boards  51 ,  52  (here, polarization films  53 ,  53  are so disposed as to sandwich the active matrix board  51  and the opposite board  52 ). 
         [0034]    Besides, an FPC (Flexible Printed Circuits) board  11  that has flexibility is disposed on an outer edge of the active matrix board  55  in the liquid crystal display device  59 . In detail, the FPC board (circuit board)  11  is a board that includes a supply wiring (not shown) that flows an electric current from a not-shown power supply; and is connected to the liquid crystal display panel  59 . And, the supply wiring of the FPC board  11  is connected, for example, to a driver (not shown) that controls display of the liquid crystal display panel  59 . Besides, on a board surface of the FPC board  11  that is in contact with the liquid crystal display panel  59 , an LED (Light Emitting Diode)  41  is disposed. 
         [0035]    Here, the FPC board  11  includes a ground pattern  12  that is able to conduct electricity (here, a ground line is omitted). In detail, the ground pattern  12  is formed on a board surface of a rear side of the board surface of the FPC  11  that is in contact with the liquid crystal display panel  59  (in short, the LED  41  and the ground pattern  12  are not present on the same board surface). 
         [0036]    The backlight unit  49  shines light onto the non-light-emitting liquid crystal display panel  59 . In other words, the liquid crystal display panel  59  receives the light (backlight) from the backlight unit  49 , thereby performing a display function. Because of this, if the light from the backlight unit  49  is able to be evenly shined onto the entire surface of the liquid crystal display panel  59 , the display quality of the liquid crystal display panel  59  improves. 
         [0037]    And, the backlight unit  49 , as shown in  FIG. 1  and  FIG. 2 , includes: the LED  41 ; a light guide plate  42 ; a reflection sheet  43 ; a diffusion sheet  44 ; optical sheets  45 ,  46 ; and a built-in chassis CS. 
         [0038]    The LED  41  is a light source and disposed on an electrode (not shown) formed on the FPC board  11  that is disposed on the liquid crystal display panel  59  thereby being supplied with an electric current to emit light. Here, to secure an amount of light, it is desirable that a plurality of the LEDs (light-emitting diode, point light source)  41  are disposed and arranged in a line on the FPC board  11 . However, in the figure, for convenience, only part of the LED  41  is shown (incidentally, hereinafter, the arrangement direction is called an arrangement direction P). 
         [0039]    The light guide plate  42  is a plate-shape member that has: a side surface  42 S; a top surface  42 U and a bottom surface  42 B which are so situated as to sandwich the side surface  42 S. And, a surface (light receiving surface) of the side surface  42 S faces the light-emitting surface of the LED  41 , thereby receiving the light from the LED  41 . The received light undergoes multiple reflection in the inside of the light guide plate  42  and goes out as area light from the top surface  42 U to outside. 
         [0040]    The reflection sheet  43  is so situated as to be covered by the light guide plate  42 . And, a surface of the reflection sheet  43  that faces the bottom surface  42 B of the light guide plate  42  serves as a reflection surface. Because of this, the reflection surface reflects the light from the LED  41  and the light traveling in the inside of the light guide plate  42  back into the light guide plate  42  without leaking both light (in detail, via the bottom surface  42 B of the light guide plate  42 ). 
         [0041]    The diffusion sheet  44  is so situated as to cover the top surface  42 U of the light guide plate  42  and diffuses the area light from the light guide plate  42 , thereby spreading the light to the entire region of the liquid crystal display panel  59  (here, the diffusion sheet  44  and the optical sheets  45 ,  46  are also collectively called an optical sheet group). 
         [0042]    The optical sheets  45  has, for example, a prism shape in the sheet surface; narrows the light directivity; and is so situated as to cover the diffusion sheet  44 . Because of this, the optical sheet  45  collets the light traveling from the diffusion sheet  44  to improve the brightness. 
         [0043]    The optical sheet  46  is so situated as to cover the optical sheet  45 ; allows a polarized-light component in a direction to pass through, while reflecting a polarized-light component in a direction perpendicular to the passing-through polarized light component. And, the optical sheet  46  reflects and reuses a polarized-light component that is absorbed by a polarization film  53 , thereby improving the brightness of the liquid crystal display panel  59 . 
         [0044]    The built-in chassis CS is a frame-shape base that encloses and holds the above various members. In detail, the built-in chassis CS stacks up and holds the reflection sheet  43 ; the light guide plate  42 ; the diffusion sheet  44 ; the optical sheets  45 ,  46  in this order (here, the stack-up direction is called a stack-up direction Q, while a direction (e.g., perpendicular direction) intersecting the arrangement direction P and the stack-up direction Q is called an intersection direction R). 
         [0045]    And, in the above backlight unit  49 , the light from the LED  41  goes out from the top surface  42 U as the area light due to the multiple reflection in the inside of the light guide plate  42 ; the area light passes through the optical sheet group ( 44  to  46 ), thereby going out as the backlight whose brightness is improved. And, the backlight reaches the liquid crystal display panel  59 , so that the liquid crystal display panel  59  displays an image by means of the backlight. 
         [0046]    The front bezel BZ 1  is a frame body that has: a frame piece  31 ; and a side wall WL (outside wall WL 1 ) that goes up from an outer edge of the frame piece  31 . Here, the material of the front bezel BZ 1  is not especially limited; and may be a resin or a metal. 
         [0047]    The rear bezel BZ 2  is a box body that has: a bottom surface  33 ; and a side wall WL (inside wall WL 2 ) that goes up from an outer edge of the bottom surface  33 . And, the rear bezel BZ 2  is formed of an electro-conductive material (e.g., metal). However, if it is an electro-conductive material, the kind of the metal is not especially limited. 
         [0048]    And, the rear bezel BZ 2  houses the backlight unit  49 ; and the built-in chassis CS of the backlight unit  49  supports the liquid crystal display panel  59 . In detail, a frame piece CSf of the built-in chassis CS supports the active matrix board  51 , so that the built-in chassis CS holds the liquid crystal display panel  59 . 
         [0049]    Here, in the case where the built-in chassis CS in the rear bezel BZ 2  supports the liquid crystal display panel  59 , the FPC board  11  disposed on the active matrix board  51 , as shown in  FIG. 1 , so bends (clings) as to cover the frame piece CSf of the built-in chassis CS, thereby situating the LED  41  on the side surface  42 S of the light guide plate  42 . Accordingly, between the built-in chassis CS and the rear bezel BZ 2 , the FPC board  11  is present (here, the package in which the built-in chassis CS and the FPC board  11  are disposed in the rear bezel BZ 2  that is the housing is also called an electronic package PG). 
         [0050]    And, the front bezel BZ 1  covers the rear bezel BZ 2 , which houses the backlight unit  49 , and serves as a lid for the rear bezel BZ 2 . According to this, the rear bezel BZ 2  and the front bezel BZ 1  house the backlight unit  49  and the liquid crystal display panel  59  (here, it is possible to call both bezels BZ 1 , BZ 2  a housing because the bezels BZ 1 , BZ 2  house the liquid crystal display panel  59  and the backlight unit  49 ). 
         [0051]    Here, by means of  FIG. 3A  to  FIG. 3C  besides  FIG. 1  and  FIG. 2 , it is described how the ground pattern  12  of the FPC board  11  secures the conduction (in other words, a connection structure between the ground pattern  12  and a conductive portion is described). Here,  FIG. 3A  is a plan view showing the bottom surface  33  of the rear bezel BZ 2 ;  FIG. 3B  is a sectional view taken along and viewed from an arrow B-B′ line of  FIG. 3A ; and  FIG. 3C  is a perspective view showing the bottom surface  33  of the rear bezel BZ 2 . 
         [0052]    First, the rear bezel BZ 2  that faces the ground pattern  12  is described. The rear bezel BZ 2 , as shown in  FIG. 3A , includes a claw portion (conductive portion)  22  that is formed by means of a parenthesis-shape (e.g., U shape) cut ST disposed through the bottom surface  33 . In detail, with respect to a stem portion  33 T b  of a tongue piece  33 T that occurs from the cut ST, the tongue piece  33 T warps up (rises) from the rear bezel BZ 2  toward the front bezel BZ 1 , so that the claw portion  22  is completed (see  FIG. 3B  and  FIG. 3C ; here, it is also possible to say that the claw portion  22  is the same as the tongue piece  33 T). 
         [0053]    And, the position of the claw portion  22 , as shown in  FIG. 1 , faces the ground pattern  12  of the FPC board  11  that bends to cling to the frame piece CSf of the built-in chassis CS. In detail, on part of the FPC board  11  that clings to the frame piece CSf, especially on part of the FPC board  11  that lies on a surface of the frame piece CSf which faces toward the rear bezel BZ 2 , the ground pattern  12  is formed and the position of the claw portion  22  is decided to match the position of the ground pattern  12 . 
         [0054]    And, the claw portion  22  is formed of a metal that is the material of the rear bezel BZ 2  and warps up with respect to the bottom surface  33  of the rear bezel BZ 2 . Because of this, when the FPC board  11  comes close to the bottom surface  33  of the rear bezel BZ 2 , the ground pattern  12  of the FPC board  11  is situated between the frame piece CSf of the built-in chassis CS and the claw portion  22 , and touches the claw portion  22 . 
         [0055]    According to this, the ground pattern  12  is sandwiched between the two members (built-in chassis CS and rear bezel BZ 2 ), so that the ground pattern  12  becomes unlikely to excessively deviate and surely touches the claw portion  22 . Because of this, static electricity flows to the rear bezel BZ 2  via the ground pattern  12 , so that various disadvantages due to the static electricity do not occur in the various circuits in the liquid crystal display device  69  (the liquid crystal display device  69  to which so-called ESD (Electro Static Discharge) measures are applied is completed). Moreover, the various circuits in the liquid crystal display device  69  are not influenced by the static electricity, so that it is also possible to say that the liquid crystal display device  69  has EMC (Electro Magnetic Compatibility). 
         [0056]    Besides, the claw portion  22  is a linear metal piece that warps up from the bottom surface  33  of the rear bezel BZ 2 . Because of this, when the claw portion  22  is pushed against the bottom surface  33 , the claw portion  22  generates restoration force that tries to return to the original state (in short, the claw portion  22  has elasticity). 
         [0057]    Accordingly, when the FPC board  11  comes close to the bottom surface  33  of the rear bezel BZ 2  until the ground pattern  12  pushes the claw portion  22 , the claw potion (push piece)  22  counters the push force to push the ground pattern  12  against the built-in chassis CS, thereby firmly touching the ground pattern  12  (in short, the ground pattern  12  touches the built-in chassis CS and the claw portion  22  while being sandwiched, so that the ground pattern  12  and the claw portion  22  firmly touch each other). Because of this, the static electricity surely escapes to the rear bezel BZ 2  via the ground pattern  12 . 
         [0058]    Besides, the tip end  22 T of the claw portion  22 , as shown in  FIG. 3A  and  FIG. 3C , has a semicircle shape. In other words, the claw portion  22  has the tip end  22 T whose outer edge is rounded. And, the rounded tip end  22 T pushes the ground pattern  12  toward the frame piece CSf of the built-in chassis CS. Because of this, even if the claw portion  22  firmly pushes the ground pattern  12 , the ground pattern  12  is not broken. 
         [0059]    Besides, the claw portion  22  pushes the ground pattern  12  against the built-in chassis CS, so that the claw portion  22  does not excessively warp up with respect to the bottom surface  33  of the rear bezel BZ 2 . Accordingly, problems that the claw potion  22  causes because of an excessive warpage of the claw portion  22 , for example, such troubles that a user is injured by the claw portion  22 , and the claw portion  22  is ripped off to fall from the rear bezel BZ 2  become unlikely to happen. 
       Embodiment 2  
       [0060]    An embodiment 2 is described. Here, members that have the same functions as those of the members which are used in the embodiment 1 are indicated by the same reference numbers and description of them is skipped. 
         [0061]    In the liquid crystal display device  69  according to the embodiment 1, part of the rear bezel BZ 2 , which faces the ground pattern  12 , is the claw portion  22 . And, the claw portion  22  is formed by the cut ST disposed through the rear bezel BZ 2 . However, the conductive portion that touches the ground pattern  12  is not limited to the claw portion  22 . 
         [0062]    Hereinafter, in the embodiment 2, another example of the claw portion  22  that is the conduction portion is described by means of  FIG. 4 ,  FIG. 5 , and  FIG. 6A  to  FIG. 6C . Here,  FIG. 4 ,  FIG. 5  and  FIG. 6A  to  FIG. 6C  are shown in similar ways to  FIG. 1 ,  FIG. 2  and  FIG. 3A  to  FIG. 3C , respectively. 
         [0063]    As shown in  FIG. 4  and  FIG. 5 , the rear bezel BZ 2  is provided with a semispherical (curved-surface) swell portion (push piece)  23  that swells from the bottom surface  33  toward the front bezel BZ 1  side. And, the swell portion  23 , like the claw portion  22 , faces the ground pattern  12  of the FPC board  11  that bends to cling to the frame piece CSf of the built-in chassis CS (see  FIG. 4 ). 
         [0064]    Because of this, when the FPC board  11  comes close to the bottom surface  33  of the rear bezel BZ 2 , the ground pattern  12  of the FPC board  11  is situated between the frame piece CSf of the built-in chassis CS and the swell portion  23 , and touches the swell portion  23 . 
         [0065]    Accordingly, even such swell potion  23  brings the same effects as those the claw portion  22 . In other words, in the liquid crystal display device  69 , static electricity flows to the rear bezel BZ 2  via the ground pattern  12 , so that various disadvantages due to the static electricity do not happen. 
         [0066]    Besides, the swell portion  23  swells from the bottom surface  33  (a surface) of the rear bezel BZ 2 , while a tip end of the swelling is formed into a curved surface. Because of this, the tip end  23 T of the curved surface pushes the ground pattern  12  toward the frame piece CSf of the built-in chassis CS. Accordingly, even if the swell portion  23  firmly pushes the ground pattern  12 , the ground pattern  12  is not broken. 
         [0067]    Here, the swell portion  23  is relatively small and has a grain shape, so that the swell potion  23  has relatively small elasticity compared with the claw portion  22  (in short, the swell portion  23  has almost no elasticity). Because of this, the position of another member (e.g., built-in chassis CS) that touches the swell portion  23  directly or indirectly is likely to deviate. 
         [0068]    However, in a case where the rear bezel BZ 2  including such swell portion  23  is employed in the liquid crystal display device  69 , as shown in  FIG. 4 , in light of the shape of the swell portion  23 , a recess VG may be formed in the built-in chassis CS. In other words, the recess VG, which is able to house at least part of the swell portion  23  and part of the ground pattern  12  that touches the swell portion  23  (and part of the FPC board  11  on which the ground patter  12  lies), may be formed in the built-in chassis CS 
         [0069]    According to this, in the liquid crystal display device  69 , the built-in chassis CS does not touch the swell portion  23  and does not deviate. Because of this, a disadvantage caused by deviation of the built-in chassis CS, for example, a positional deviation of the liquid crystal display panel  59  with respect to the backlight unit  49  does not happen, so that the image quality of the liquid crystal display panel  59  is kept. 
         [0070]    However, such recess VG of the built-in chassis CS is not a must. Because, even if there is not the recess VG, if the swell potion  23  has a grain shape and does not have such a size that deviates the built-in chassis CS and the like, the recess VG is unnecessary. 
         [0071]    In the case where there is not the recess VG, like the claw portion  22 , when the FPC board  11  comes close to the bottom surface  33  of the rear bezel BZ 2 , the ground pattern  12  touches the built-in chassis CS and the swell portion  23  while being sandwiched. Accordingly, the ground pattern  12  and the swell portion  23  firmly touch each other. In this case, the static electricity surely escapes to the rear bezel BZ 2  via the ground pattern  12 . 
         [0072]    Besides, the swell portion  23 , unlike the claw portion  22 , is not formed by the cut ST disposed through the rear bezel BZ 2 . Because of this, as for the rear bezel BZ 2  including the swell portion  23 , foreign matter such as dust and the like does not invade the inside of the liquid crystal display device  69  via an opening like the cut ST. 
       Other Embodiments  
       [0073]    Here, the present invention is not limited to the above embodiments; and various modifications are possible without departing from the spirit of the present invention. 
         [0074]    For example, it is desirable that in the liquid crystal display device  69 , the material of the front bezel BZ 1  is also an electro-conductive material like the rear bezel BZ 2 . The reason is that because the rear bezel BZ 2  and the front bezel BZ 1  touch each other, static electricity escapes more easily via the electro-conductive portion such as the claw portion  22  (and the swell portion  23 ). 
         [0075]    Besides, in the above description, The LED  41  is described as the light source; however, this is not limiting. For example, light-emitting elements, which are composed of self-light-emitting materials such as a fluorescent lamp like a cold cathode fluorescent lamp, an organic EL (Electro-Luminescence) and the like, may be employed as the light source. 
         [0076]    Lastly, it is possible to say that electronic apparatuses which incorporate a display device such as the above liquid crystal display device  69  and the like, for example, a notebook-sized personal computer, a mobile phone, a PDA (Personal Digital Assistant) are also the present invention.
