Description

  The present invention relates to a liquid crystal module used as a display device of an electronic device such as a television receiver or a microcomputer, and more particularly to a support member that supports a linear light source for backlight provided in the liquid crystal module.

  Conventionally, liquid crystal modules have been used as display devices for electronic devices such as television receivers and microcomputers. FIG. 7 is an exploded perspective view showing a configuration of a conventional liquid crystal module. The configuration of the conventional liquid crystal module 100 will be described with reference to FIG. A conventional liquid crystal module 100 includes a rear frame 1, a reflection sheet 2, a backlight light source 3, a diffusion plate 4, an optical sheet 5, and a liquid crystal panel 6.

  The rear frame 1 is made of metal, for example, and has a structure that can accommodate the reflection sheet 2 and the backlight light source 3. The reflection sheet 2 is formed of, for example, an insulating white synthetic resin plate and is placed on the rear frame 1. The reflection sheet 2 is provided to reflect light emitted from the backlight light source 3.

  The backlight light source 3 is formed by collecting a plurality of linear light sources 3a. In the conventional liquid crystal module 100 shown in FIG. 7, the number of the linear light sources 3a is sixteen. The linear light source 3a is specifically composed of a cold cathode fluorescent lamp (CCFL), but in the liquid crystal module 100, two linear light sources 3a are paired to constitute one CCFL 3b. It is supposed to be. That is, one end portions of the two linear light sources 3a are connected to each other to form one U-shaped CCFL 3b.

  The U-shaped CCFL 3b is supported at one end by a lamp holder 7 made of an elastic member such as silicon rubber. The other end is inserted into the lamp socket 8, and the CCFL 3b is connected to an inverter circuit (not shown) through the lamp socket 8. Such a U-shaped CCFL 3b is driven by applying alternating voltages to both ends of the CCFL 3b so as to be in opposite phases. Although a liquid crystal module including a U-shaped CCFL is shown here, a liquid crystal module including a straight tube CCFL may be used, for example.

  The diffusing plate 4 has a function of diffusing the light directly emitted from the backlight light source 3 and the light incident after being reflected by the reflection sheet 2 after being emitted from the backlight light source 3. Further, the optical sheet 5 includes a diffusion sheet for diffusing light, and here, the incident light is diffused to correct luminance unevenness and the like. The diffusion plate 4 and the optical sheet 5 are pressed against the rear frame 1 by the cell guide 9.

  A liquid crystal panel 6 is disposed on the upper side of the optical sheet 5. The liquid crystal panel 6 has a known structure including a pair of polarizing filters, a pair of glass substrates provided between the polarizing filters, and a liquid crystal, a transparent electrode, a color filter, and the like provided between the glass substrates. Have. The position of the liquid crystal panel 6 is regulated by the cell guide 9 and is fixed by the bezel 10.

  Although the entire configuration of the liquid crystal module 100 is as described above, the linear light source 3a constituting the backlight light source 3 is thin and particularly long in the case of a liquid crystal module for a large screen. The rigidity of the is reduced. For this reason, as shown in FIG. 8, in the conventional liquid crystal module 100, the support member 101 which supports the linear light source 3a in the substantially intermediate position of the longitudinal direction is arrange | positioned (for example, refer patent document 1).

  FIG. 9 is a side view illustrating a configuration of a support member 101 that is provided in the conventional liquid crystal module 100 and supports the linear light source 3a. FIG. 10 is a schematic plan view showing a configuration of an insertion hole provided so that the support member 101 can be attached to the rear frame 1 provided in the conventional liquid crystal module 100. In FIG. 10, the support member 101 is indicated by a broken line in order to facilitate understanding of the positional relationship between the insertion hole provided in the rear frame 1 and the support member 101.

  As shown in FIG. 9, the support member 101 includes a base part 111, a plurality of truncated circular holding parts 112 projecting from the base part 111 and holding the linear light source 3 a, and the base part 111. The support member 101 is provided in the first insertion hole 121 (see FIG. 10) provided in the substantially central portion of the surface opposite to the surface on which the holding portion 112 is provided, and the support member 101 is removed from the rear frame 1. A first engagement portion 113 that engages with the rear frame 1 so as not to come off, and is provided on both ends of the same surface as the surface on which the first engagement portion 113 is provided, and is provided on the rear frame 1. And a second engagement portion 114 that is inserted into the two insertion holes 122 (see FIG. 10) and engages the rear frame 1 so that both end portions of the support member 101 are fixed.

  The support member 101 is provided with a protruding portion 115 at a substantially central portion of the same surface as the surface on which the holding portion 112 of the base portion 111 is provided. The projection 115 has a function of preventing the diffuser plate 4 provided in front of the backlight light source 3 from being bent backward and coming into contact with the linear light source 3a. That is, the support member 101 provided in the conventional liquid crystal module 100 has a function of preventing the contact between the linear light source 3a and the diffusion plate 4 in addition to the function of supporting the linear light source 3a.

  The first engaging portion 113 included in the support member 101 has a substantially U shape, and a part of the first engaging portion 113 (in the direction indicated by the arrow in FIG. 9) has a substantially rectangular shape provided in the rear frame 1. The insertion hole 121 is longer than the longitudinal direction (indicated by an arrow in FIG. 10). Therefore, when the first engaging portion 113 of the support member 101 formed of a flexible material is inserted into the first insertion hole 121, the support member 101 does not come out of the rear frame 1. , Engage with the rear frame 1.

  In addition, the second engaging portion 114 included in the support member 101 includes a rod-like portion 114a that extends substantially perpendicularly from the base portion 111 and a plate-like portion 114b that is substantially parallel to the base portion 111. A part of the base 111 protrudes from the base 111 in a direction parallel to the longitudinal direction of the base 111. The second insertion hole 122 provided in the rear frame 1 is formed so as not to protrude from the base portion 111 in a state where the first engagement portion 113 is inserted into the first insertion hole 121. (See FIG. 10). For this reason, when the second engaging portion 114 is inserted into the second insertion hole 122, a part of the plate-like portion 114a is engaged with the rear frame 1, and the end portion of the support member 101 is warped. Without being fixed to the rear frame 1.

  In addition, since there is the reflection sheet 2 between the support member 101 and the rear frame 1, the reflection sheet 2 also has a hole into which the first engagement portion 113 and the second engagement portion 114 are inserted. Is formed. This point is omitted in FIG.

  Patent Document 1 discloses a support member (represented as a lamp clip in Patent Document 1) having a mounting structure different from the mounting structure of the support member 101 described above. Also briefly explain.

The lamp clip shown in Patent Document 1 has a large diameter portion formed thicker than a root portion (small diameter portion) on the distal end side of the foot portion. In addition, the reflector plate and the shield plate into which the lamp clip is inserted are a combination of a large circle portion larger than the large diameter portion and a small circle portion smaller in diameter than the large circle portion and larger in diameter than the root small diameter portion. In addition, a saddle-shaped hole in which the width of the constricted portion where the large circle portion and the small circle portion are in contact with each other is substantially the same as or slightly wider than the small diameter portion at the base is formed. And by this, by inserting the foot part of the ramp clip from the front to the large circle part of the saddle-shaped hole to the root part, the foot part is moved to the small circle part side through the constricted part. The lamp clip can be detachably attached to the shield plate.
Japanese Patent No. 3854625

  However, in the support member 101 that supports the linear light source 3a of the above-described conventional liquid crystal module 100, the first engagement portion 113 formed in a substantially U shape protrudes from the rear frame 1. There is a possibility that the first engaging portion 113 protruding from the rear frame 1 is pushed by the influence of vibration, impact, etc., and the support member 111 is detached from the rear frame 1. In this case, the linear light source 3a supported by the support member 101 may be damaged, which causes a problem. For this reason, in the prior art, as shown in FIG. 11, a protective portion 131 that protects the first engaging portion 113 is provided by raising the rear frame 1. Since the protective part 131 is higher than the first engaging part 113, the first engaging part 113 is not pushed by the influence of vibration, impact, or the like.

  However, when the rear frame 1 is cut and raised in this way to form the protection part 131, the rear frame 1 needs to be processed. Further, such a protection part 131 protrudes from the rear surface of the rear frame 1 and is obstructive. From such points, it is preferable not to provide the protection part 131 formed by cutting and raising. In the case of the configuration of the conventional support member 101, when the second engagement portion 114 is inserted into the second insertion hole 122, the support member 101 needs to be bent and inserted. There was also the possibility of damage.

  Further, in Patent Document 1, since the diameter of the constricted portion is formed to be substantially the same as or slightly wider than the base small-diameter portion, the fixing of the lamp clip (supporting member that supports the linear light source) is not sufficient. There is a problem that the linear light source may move when it is attached to the lamp clip.

  In view of the above problems, an object of the present invention is to provide a liquid crystal module that can securely fix a support member that supports a linear light source for a backlight to a mounted plate. Another object of the present invention is to provide a liquid crystal module capable of reducing the load applied to the support member when the support member for supporting the linear light source for the backlight is mounted and removed while achieving the above-mentioned object. Is to provide.

  In order to achieve the above object, the present invention includes a liquid crystal panel, a plurality of linear light sources arranged on the back side of the liquid crystal panel, and a plurality of holding portions for holding the linear light sources, In a liquid crystal module comprising: a supporting member that supports a light source; and a mounting plate that is provided on the back side of the linear light source and to which the supporting member is mounted. The mounting plate includes two types of different shapes. When the hole is formed and one of the two types of holes is the first hole and the other is the second hole, the holding portion of the base portion where the holding portion of the support member is formed is formed. The surface opposite to the surface to be inserted can be inserted into and removed from the first hole only when it is arranged in a predetermined direction. If the direction is different from the direction of the A first engaging portion that engages with the plate, and a first engaging portion that engages with the mounted plate so that a part of the support member is fixed by being inserted into the second hole and rotated by a predetermined amount. 2 engaging portions are formed.

  According to this configuration, the support member that supports the linear light source is unlikely to be detached from the mounted plate without forming a protective portion on the mounted plate as in the prior art. In addition, since the support member is mounted and fixed by rotation, the load on the support member can be reduced when the support member is mounted on the mounted plate and when the support member is detached from the mounted plate.

  According to the present invention, in the liquid crystal module having the above structure, the mounting plate further includes a third hole having a shape different from the first hole and the second hole, and the base portion. Positioning protrusions for positioning the support member at a predetermined mounting position by contacting the inner wall of the third hole on the surface on which the first engagement portion and the second engagement portion are formed May be further formed. According to this structure, the structure for positioning a support member in a predetermined position is realizable at low cost.

  According to the present invention, in the liquid crystal module having the above configuration, the first engagement portion is formed at a substantially central portion of the base portion, and the second engagement portion is at both end portions of the base portion. The positioning protrusions may be formed between the first engaging portion and the second engaging portion. According to this configuration, the support member can be disposed at a predetermined mounting position and securely fixed.

  In the liquid crystal module having the above-described configuration, the first engagement portion and the second engagement portion each include a plate-like portion disposed substantially in parallel with the base portion, When the first engaging portion and the mounted plate are engaged, and when the second engaging portion and the mounted plate are engaged, the plate-shaped portion and the back surface of the mounted plate are in contact with each other. It does n’t matter if you touch.

  Further, according to the present invention, in the liquid crystal module having the above configuration, the plate-like portion is formed with a convex portion that protrudes toward the back surface of the mounted plate, and the convex portion is in contact with the back surface of the mounted plate. Is preferred. According to this configuration, when the support member is rotated to the predetermined mounting position, the rotation can be performed smoothly.

  Further, according to the present invention, in the liquid crystal module configured as described above, the base portion is formed so as to cover a hole provided for mounting the support member when the support member is positioned at a predetermined mounting position. It is preferable. According to this configuration, the efficiency of light emitted from the linear light source can be reduced without using an extra member.

  In the liquid crystal module having the above-described configuration, the predetermined mounting position of the support member may be a position obtained by rotating the support member approximately 90 degrees from the predetermined direction. According to this configuration, it is possible to easily realize a configuration in which the support member is not easily detached from the mounted plate.

  According to the present invention, in the liquid crystal module having the above-described configuration, a reflective member that reflects light emitted from the linear light source is provided between the support member and the mounted portion. A through-hole penetrating through a portion formed on the surface of the base portion opposite to the surface on which the holding portion is formed for mounting on the mounted portion may be formed.

  According to the present invention, in the liquid crystal module having the above-described configuration, contact between the linear light source and a member disposed in front of the linear light source is prevented from being formed on the surface of the base portion where the holding portion is formed. It does not matter if a protruding part is provided. According to this configuration, functions other than the function of supporting the linear light source can be added to the support substrate.

  According to the liquid crystal module of the present invention, the support member that supports the linear light source for backlight can be reliably fixed to the mounted plate. In addition, according to the liquid crystal module of the present invention, the load applied to the support member can be reduced when the support member that supports the linear light source for the backlight is attached and detached while achieving the above-described object.

  Hereinafter, embodiments of a liquid crystal module of the present invention will be described with reference to the drawings. In addition, embodiment shown here is an example and this invention is not limited to embodiment shown here.

  The overall configuration of the liquid crystal module 50 of the present embodiment is the same as the overall configuration of the conventional liquid crystal module 100 shown in FIG. However, the structure of the support member 101 that supports the linear light source 3a shown in FIGS. 8 to 11 and the structure to which the support member 101 is fixed are different from the conventional one. Accordingly, in describing the liquid crystal module 50 of the present embodiment, differences from the conventional liquid crystal module 100 will be mainly described. In addition, the same reference numerals are given to portions overlapping with the conventional liquid crystal module 100, and the description thereof is omitted unless particularly necessary.

  First, the support member 11 that supports the linear light source 3a provided in the liquid crystal module 50 of the present embodiment will be described with reference to FIGS. 1, 2, and 3. FIG. FIG. 1 is a schematic perspective view showing the configuration of the support member 11 provided in the liquid crystal module 50 of the present embodiment. FIG. 2 is a schematic side view showing the configuration of the support member 11 provided in the liquid crystal module 50 of the present embodiment. FIG. 3 is a schematic plan view when the support member 11 provided in the liquid crystal module 50 of the present embodiment is viewed from the lower side.

  A holding part 13, a first engaging part 14, a second engaging part 15, a positioning protrusion 16, and a protruding part 17 are formed on the base part 12 of the support member 11. . The support member 11 is formed of a resin such as polycarbonate (PC), for example, and the whole is integrally formed by injection molding or the like. Moreover, the support member 11 is formed in white so that the light from the linear light source 3a can be reflected.

  The holding part 13 is formed on the upper surface 12 a of the base part 12. The holding portion 13 is provided with an oval portion, and the linear light source 3a is held by the oval portion. Moreover, the base part 12 is provided with a plurality (eight in this embodiment) of holding parts 13, which are arranged in a substantially straight line. Among the plurality of holding portions 13 formed on the base portion 12, the intervals between the adjacent holding portions 13 are substantially the same.

  The first engagement portion 14 is formed at a substantially central portion of the lower surface of the base portion 12. The first engaging portion 14 is connected to the base portion 12 via the first protruding portion 14a that protrudes in a substantially vertical direction from the lower surface 12b of the base portion 12 and the first protruding portion 14a. And comprises a first plate-like portion 14b formed substantially parallel to the lower surface 12b of the base portion 12.

  The first projecting portion 14a is a cylinder with a thin root portion NE, and the tip of the cylinder is in a state where two flat plates intersect in a cross shape. In addition, although the 1st protrusion part 14a may make the whole shape cylindrical, in this embodiment, in order to reduce the influence of sink marks at the time of shaping | molding of the support member 11, a 1st protrusion part The whole 14a is not made cylindrical, but has the above-described configuration. Further, the first plate-like portion 14 b is formed in a substantially rectangular shape whose longitudinal direction is substantially parallel to the longitudinal direction of the base portion 12.

  The second engaging portion 15 is formed at both ends of the lower surface 12 of the base portion 12. The second engaging portion 15 is connected to the base portion 12 via the second protruding portion 15a protruding in a substantially vertical direction from the lower surface 12b of the base portion 12 and the second protruding portion 15a. And a second plate-like portion 15b formed substantially parallel to the lower surface 12b of the base portion 12. The 2nd protrusion part 15a is comprised by the substantially rectangular shaped flat plate, and it is formed so that the plate | board surface may be substantially orthogonal to the longitudinal direction of the base part 12. As shown in FIG. Further, the second plate-like portion 15b is formed in a substantially square shape.

  The positioning protrusion 16 is formed on the lower surface 12b side of the base portion 12 and at a substantially intermediate position between the positions where the first engagement portion 14 and the second engagement portion 15 are provided. The positioning protrusion 16 is formed in a substantially cylindrical shape. Note that the amount of protrusion of the positioning protrusion 16 from the base portion 12 is smaller than that of the first engaging portion 14 and the second engaging portion 15. In addition, as shown in FIG. 3, the 1st engaging part 14, the 2nd engaging part 15, and the protrusion 16 for positioning are located in a line on the substantially straight line.

  The protruding portion 17 is formed at a substantially central portion on the upper surface side of the base portion 12. Although the details of the protruding portion 17 are not shown, the tip portion is rounded. Moreover, the protrusion amount of the protrusion part 17 is larger than the protrusion amount of the holding part 13 formed in the same surface of the base part 12, and this protrusion part 13 is arrange | positioned ahead of the linear light source 3a. The diffusion plate 4 is prevented from bending and coming into contact with the linear light source 3a.

  Next, the structure of the part to which the support member 11 is attached will be described with reference to FIG. FIG. 4 is a schematic plan view showing configurations of the rear frame 1 and the reflection sheet 2 of the present embodiment. The support member 11 is attached to the rear frame 1, but in the liquid crystal module 50 of the present embodiment, the reflection sheet 2 exists between the support member 11 and the rear frame 1. For this reason, when attaching the support member 11 to the rear frame 1, it is necessary to process the reflective sheet 2, so the configuration of the reflective sheet 2 will be described together.

  As shown in FIG. 4, the rear frame 1 and the reflection sheet 2 are necessary for mounting one supporting member 11 on the right side and the left side with respect to the bisector A that bisects the rear frame 1. A plurality of holes are formed. In the present embodiment, two support members 11 are mounted. This is because the liquid crystal module 50 is large and the number of linear light sources 3a is very large. That is, when it is going to support many linear light sources 3a with one support member 11, since the support member 11 becomes too large and the problem arises in the handling surface, the support member 11 is divided into two. . The reason why the bisector A is divided into the right side and the left side is that it is easier to dispose the two support members 11 by shifting their positions. Therefore, the number of support members 11 and the arrangement method thereof are not limited to the configuration of the present embodiment, and may be appropriately changed according to the size of the liquid crystal module 50 and the like.

  Since the configuration of the holes provided on the left and right sides of the bisector A is substantially the same on the left and right, only the plurality of holes formed on the right side of the bisector A will be described below. In FIG. 4, the drawings shown at the tip of the broken-line arrows are enlarged views of the holes on the root side of the broken lines. As shown, there are three types of holes (first hole HA, second hole HB, and third hole HC) formed in the rear frame 1. Of the holes formed on the right side of the bisector A, the holes formed in the uppermost and lowermost rear frames 1 overlap when one of them is rotated 180 degrees, and the shape of the hole is Same shape.

  Of these three types of holes having different shapes, the first hole HA is provided in a substantially rectangular shape, and only the central portion thereof has a circular shape. As will be described later, the first engagement portion 14 is inserted into and removed from the first hole HA. The second hole HB is provided in a substantially convex shape, and the second engagement portion 15 is inserted and removed as will be described later. The third hole HC is a substantially rectangular long hole whose longitudinal direction is the same as the longitudinal direction of the base part 12, and the positioning projection 16 is inserted into and removed from the third hole HC.

  In the present embodiment, the first hole HA, the second hole HB, and the third hole HC are all through holes. However, the third hole HC is not necessarily a through hole.

  There are two types of holes having different shapes as shown in FIG. 4 in the through holes formed in the reflection sheet 2 in order to attach the support member 11 to the rear frame 1. The through holes 21 to 23 provided on the first hole HA and the third hole HC are all circular, and these are sufficient for the first hole HA and the third hole HC. It is made large so that it can be exposed. On the other hand, the through holes 24 and 25 provided on the second hole HB are provided in a substantially convex shape, and are larger than the second hole HB. The reason why the through-holes 21 to 25 formed in the reflection sheet 2 are formed in such a large size is in consideration of workability when the support member 11 is mounted.

  Note that the through holes 21 to 23 formed on the first hole HA and the second hole HC may have the same shape as the holes formed on the rear frame 1. Even in this case, it is preferable that the through hole formed in the reflection sheet 2 is not formed to be the same size as the hole formed in the rear frame 1 and is formed to be large.

  Next, a procedure for attaching the support member 11 to the rear frame 1 will be described with reference to FIG. FIG. 5 is a diagram illustrating a state in which the support member 11 is mounted on the rear frame 1. FIG. 5A illustrates an initial state in the case where the support member 11 is mounted on the rear frame 1, and FIG. ) Shows a state where the support member 11 is mounted on the rear frame 1 (a state where the support member 11 is disposed at a predetermined mounting position).

  When the support member 11 is mounted on the rear frame 1, first, the support member 11 is arranged in the direction shown in FIG. When arranged in this manner, the shapes of the first engagement portion 14 of the support member 11 and the first hole HA formed in the rear frame 1 match, and the first engagement portion 14 is moved to the first hole HA. And the first plate-like portion 14b can penetrate the first hole HA. As a result, the support member 11 can rotate with the first engagement portion 14 inserted into the first hole HA. Then, the support member 11 is rotated in the direction of the arrow (clockwise direction) shown in FIG.

  When the support member 11 is rotated, the first plate-like portion 15 b comes into contact with the back surface of the rear frame 1, and the support member 11 cannot be removed from the rear frame 1. When the support member 11 is further rotated, the second plate-like portion 15b of the second engaging portion 15 comes over the second hole HB. Although there are two second engaging portions 15, both are the same (the same applies below). The second plate-like portion 15a can be inserted into the rectangular portion HB1 having the larger area of the second hole HB formed in a substantially convex shape. At this point, the second plate-like portion 15b is inserted into the second hole HB (exactly HB1 portion) and penetrated.

  Thereafter, when the support member 11 is further rotated in the same direction (clockwise direction), the second protrusion 15a (which is a flat plate) of the second engagement portion 15 has a smaller area of the second hole HB. The rectangular portion HB2 is entered. As a result, the second plate-like portion 15 b comes into contact with the back surface of the rear frame 1. Further, when the support member 11 is further rotated and rotated 90 degrees from the state shown in FIG. 5A, the positioning protrusion 16 comes over the third hole HC, and the positioning protrusion 16 is inserted into the hole HC. Inserted into. Although there are two positioning projections 16, both are the same (the same applies below). The width W (see FIG. 4) of the third hole HC, which is a long hole, is substantially the same as the diameter of the positioning protrusion 16 formed in a columnar shape. Is restricted, and the mounting of the support member 11 to the rear frame 1 is completed.

  As shown in FIG. 5B, when the support member 11 is mounted on the rear frame 1, the plurality of holes provided in the rear frame 1 and the reflection sheet 2 are covered. Thereby, the loss of light does not occur by forming the through hole in the reflection sheet 2 in order to mount the support member 11. In the present embodiment, as shown in FIG. 5B, the area of the base portion 12 of the support member 11 is widened substantially at the center portion and both end portions, whereby the rear frame 1 and the reflection sheet are formed. A plurality of holes provided in 2 are covered.

  6 is a cross-sectional view at the BB position in FIG. 5B showing a state in which the support member 11 is mounted on the rear frame 1. In FIG. 6, the rear frame 1 and the reflection sheet 2 are shown as one member for convenience. As shown in FIG. 6, in a state where the support member 11 is mounted on the rear frame 1, the first engagement portion 14 is arranged so that the first plate-like portion 14 b comes into contact with the rear surface of the rear frame 1. The frame 1 cannot be removed.

  Further, a portion where the first plate-like portion 14b and the rear surface of the rear frame 1 are in contact with each other is a convex portion 31 protruding from the plate-like surface of the first plate-like portion 14b toward the rear frame 1 side. This is because, when the plate-like surface of the first plate-like portion 14b and the rear surface of the rear frame 1 are in contact with each other, it is difficult to smoothly rotate the support member 11 when attached to the rear frame 1. That is what we consider. However, in some cases, the plate-like surface of the first plate-like portion 14b and the rear surface of the rear frame 1 may be in contact with each other.

  Further, when the support member 11 is mounted on the rear frame 1, the second engagement portion 15 does not come out of the rear frame 1 because the second plate-like portion 15 b comes into contact with the rear surface of the rear frame 1. The both ends of the support member 15 are fixed. Further, a portion where the second plate-like portion 15b and the rear surface of the rear frame 1 are in contact with each other is a convex portion 32 protruding from the plate-like surface of the second plate-like portion 15b. This is for the same reason as in the case of the first engaging portion described above, but in this case as well, the plate-like surface of the second plate-like portion 15b and the rear surface of the rear frame 1 may be in contact with each other. .

  In the embodiment described above, when the first engaging portion 14 of the support member 11 is rotated 90 degrees in the clockwise direction from the state inserted in the first hole HA (the state of FIG. 5A). In addition, the support member 11 is arranged at a predetermined mounting position. However, the present invention is not limited to this configuration, and various modifications can be made without departing from the object of the present invention. That is, for example, when the support member 11 is rotated 90 degrees in the counterclockwise direction, the support member 11 may be placed in a predetermined mounting position. Further, the support member 11 may be arranged in a predetermined mounting position by rotating the support member 11 by an amount smaller than 90 degrees. However, in this case, if the rotation amount is too small, the engagement between the first engagement portion 14 and the rear frame 1 becomes insufficient, and the support member 11 may be easily detached from the rear frame 1. That point needs attention.

  Further, in the embodiment described above, the first engagement portion 14 is formed at the substantially central portion of the base portion 12 constituting the support member 11, and the second engagement is performed at both end portions of the base portion 12. Although the portion 15 is formed and the support member 11 is mounted on the rear frame 1, the present invention is not limited to this configuration, and various modifications can be made without departing from the object of the present invention. . For example, the first engaging portion 14 shown in the present embodiment is formed at one end of the base portion 12, and the second engaging portion 15 shown in the present embodiment is formed at the other end. The support member 11 may be mounted on the rear frame 1 or the like. Also in this case, the positioning protrusion 16 can be provided between the first engaging portion 14 and the second engaging portion 15.

  Further, in the embodiment described above, the support member 11 is configured to include the positioning protrusion 16 in addition to the first engagement portion 14 and the second engagement portion 15, but the present invention is not limited thereto. Not intended. That is, the configuration for positioning the support member 11 may be formed on the rear frame 1 side, and the support member 11 may be configured without the positioning protrusion 16.

  In the embodiment described above, the reflection sheet 2 is provided between the support member 11 and the rear frame 1. However, the reflection sheet 2 is arranged by treating the surface of the rear frame 1 with the reflection surface. It can also be set as the structure which does not.

  In addition, in the present embodiment, the protrusion 17 that prevents the diffusion plate 4 and the linear light source 3a from being contacted by the bending of the diffusion plate 4 disposed in front of the support member 11 is provided. 17 may be omitted. In the present embodiment, the support member 11 is configured to support the linear light source 3a at a substantially intermediate position in the longitudinal direction. However, the position at which the support member 11 is disposed is not limited to this, and can be changed as appropriate. .

  If the liquid crystal module of the present invention is used, the support member that supports the linear light source for the backlight is unlikely to come off the mounted plate due to vibration or impact, and is supported when the support member is attached and detached. The load applied to the member can be reduced. For this reason, this invention is useful as a technique regarding a liquid crystal module.
