  Here, in the field of display devices, in order to increase the area occupied by the display surface with respect to the external dimensions of the display device, it is desired to narrow the frame area of the front cabinet. However, in Patent Document 1, in order to fix the front cabinet from the front-rear direction with the fastening member, it is necessary to secure at least a region corresponding to the maximum outer diameter of the head of the fastening member in the frame region of the front cabinet. However, the width of the frame area increases accordingly. As a result, there is a problem that it is difficult to narrow the frame area.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a display device capable of narrowing a frame area of a front cabinet.

  A display device according to an aspect of the present invention includes a front cabinet including a display unit having a display surface on the front surface, a frame-shaped frame portion surrounding the periphery of the display surface, and a protruding portion extending in the depth direction from the frame portion, And an internal frame to which the front cabinet is fixed, and the protruding portion of the front cabinet has a fixing portion fixed to the internal frame from the outside in the direction intersecting the depth direction by the fastening member.

  In the display device according to one aspect of the present invention, as described above, the protrusion extending in the depth direction from the frame portion is provided in the front cabinet, and the protrusion of the front cabinet is provided outside the direction intersecting the depth direction by the fastening member. By providing the fixing portion that is fixed to the inner frame from the inside to the inside, the fastening member can be attached in the inner direction intersecting the depth direction (front-rear direction), and the front cabinet can be fixed to the inner frame. In this case, since the axial direction of the fastening member can be directed to the width direction of the frame portion (inner direction intersecting the depth direction (front-rear direction)), unlike the case where the fastening member is fixed toward the front-rear direction, It is not necessary to provide a space in the frame portion that is larger than the maximum outer diameter of the head of the fastening member. As a result, the front cabinet can be fastened and fixed only by securing a smaller space in the frame portion, so that the frame area of the front cabinet can be narrowed.

  In the display device according to the one aspect described above, preferably, the display device further includes a rear cabinet provided so as to be continuous with the outer peripheral edge portion of the front cabinet, and the protruding portion is inside the rear cabinet, and the outer peripheral edge portion and the display portion. It is provided in the position between.

They are arranged in a separated state. If comprised in this way, even when a holding member (display part) adjoins and arranges inside a projection part (root part) for narrowing a frame, the part which a holding member separates from a root part (namely, A space can be secured on the inner side (holding member side) of the root portion by the projection amount of the convex portion. As a result, even when the outer dimensions of the front cabinet vary due to dimensional errors during manufacturing, the projection (root) presses the display part via the holding member in the assembled state, resulting in display unevenness. Can be prevented.

  In the configuration in which the fixing portion is disposed at a position shifted inward with respect to the root portion, preferably, the protruding portion has a rib-like shape extending in the depth direction from the frame portion, and the vicinity of the fixing portion of the protruding portion. Is provided with a lightening portion that facilitates bending deformation in a direction intersecting the depth direction of the protruding portion. If comprised in this way, when fastening and fixing a front cabinet in a fixing | fixed part, a front cabinet can be fixed in the state which bent and deformed the protrusion part. As a result, even if there is a variation in the outer dimensions of the front cabinet due to dimensional errors during manufacturing, the variation in size can be absorbed by the flexural deformation of the protrusions. Can be achieved.

  In this case, preferably, the lightening portion includes at least one of a cut-out notch portion provided in the projecting portion and a groove portion formed in the vicinity of the fixed portion in the projecting portion. If configured in this way, unlike the case of changing the material of the protrusion or changing the thickness of the protrusion, it is a simple structure that only forms a notch or groove in the rib-shaped protrusion, It is possible to facilitate the bending deformation of the protruding portion.

  In the display device according to the above aspect, the front cabinet preferably has an engagement portion that engages with the internal frame to restrict the rotational position shift of the front cabinet when fastened by the fastening member. With this configuration, the front cabinet can be prevented from being displaced in the rotational direction of the fastening member due to the external force in the rotational direction at the time of fastening. Therefore, even in the configuration in which the fastening member is attached from the side surface side of the front cabinet. The mounting work can be facilitated.

  In the display device according to the above aspect, preferably, the protruding portion is formed integrally with the front cabinet, and the fixing portion has a through hole that extends in a direction perpendicular to the depth direction in the protruding portion, and is fastened to the through hole. It is comprised so that it may fix to an internal frame with a fastening member in the state which passed the axial part of the member. If constituted in this way, since the protruding portion and the fixing portion can be integrally formed in the front cabinet, for example, compared to a configuration in which a separate fixing member having the protruding portion and the fixing portion is attached to the front cabinet, An increase in the number of parts and the number of assembly steps can be suppressed.

  According to the present invention, as described above, it is possible to provide a display device capable of narrowing the frame area of the front cabinet.

Accordingly, the front cabinet 2 is fixed to the rear frame 16 from the side by screws 4 at a total of 11 locations, each of 3 locations on the left and right side surfaces and 5 locations on the upper side surface.

  Since the protrusion 23 and the engagement part 24 have the same configuration, the protrusion 23 and the engagement part 24 on the X2 direction side indicated by reference numeral P in FIG. 2 will be described in detail. In addition, since the side perpendicular to the depth direction (Y direction) includes the X direction and the Z direction, hereinafter, the side is referred to as the A direction, and the direction toward the center of the display surface 11a within the XZ plane (A2 direction). Is the inside direction, and the direction (A1 direction) toward the outside of the display surface 11a in the XZ plane is called the outside direction. 3 and 6, the A direction coincides with the X direction.

  As shown in FIG. 3, the protruding portion 23 is provided inside the rear cabinet 3 and at a position between the outer peripheral wall portion 22 and the display module 1 (liquid crystal cell 11). The protruding portion 23 integrally includes a root portion 41 that is a connection portion with the frame portion 21, a fixing portion 42 on the distal end side, and a step portion 43 between the root portion 41 and the fixing portion 42.

  In the first embodiment, the fixing portion 42 is disposed at a position on the far side (Y2 direction side) in the depth direction from the liquid crystal cell 11, and is screwed at a position on the far side (Y2 direction side) from the liquid crystal cell 11. It is fixed to the rear frame 16. Specifically, the fixing portion 42 has a through hole (screw insertion hole) 44 directed to the side A orthogonal to the depth direction Y, and the rear frame 16 is formed by the screw 4 that passes the shaft portion 4a through the through hole 44. It is comprised so that it may be fixed to. The shaft portion 4a of the screw 4 inserted into the through hole 44 passes through the insertion hole 12a of the mold frame 12 in the A2 direction and is attached to the screw hole 16a of the rear frame 16. The fixing portion 42 (that is, the front cabinet 2) is fixed to the rear frame 16 by fastening the screw 4 to the screw hole 16a. As described above, the front cabinet 2 is configured to be fastened and fixed to the rear frame 16 in a state in which the screws 4 (shaft portions 4a) are arranged at positions where they overlap the liquid crystal cell 11 in the depth direction Y.

  In the first embodiment, the fixing portion 42 of the protruding portion 23 is disposed at a position shifted from the root portion 41 to the inner side (A2 direction side) of the side A that is orthogonal to the depth direction Y. That is, the contact surface of the fixing portion 42 with the mold frame 12 (the inner surface 23a of the protruding portion 23) is disposed at a position shifted in the A2 direction on the display module 1 (liquid crystal cell 11) side with respect to the root portion 41. Has been.

  Specifically, the protruding portion 23 is formed so as to extend linearly in the depth direction (Y direction) from the root portion 41 to the stepped portion 43. The stepped portion 43 is formed so as to protrude in the inner direction A2 perpendicular to the depth direction toward the fixed portion 42 at a position on the back side (Y2 direction side) with respect to the arrangement position of the liquid crystal cell 11. The stepped portion 43 is arranged at a position in the protruding portion 23 at a distance D3 (= the length of the linear portion of the protruding portion 23) larger than the distance D2 from the root portion 41 to the arrangement position of the liquid crystal cell 11. . As a result, the fixing part 42 on the tip side of the step part 43 is disposed at a position shifted inward by the distance D1 with respect to the root part 41. Due to the stepped portion 43, a space corresponding to the width D1 and the depth D3 is formed between the display module 1 (mold frame 12) and the protruding portion 23.

  Further, in the stepped portion 43, not only the inner surface 23a of the protruding portion 23 but also the outer surface 23b on the A1 direction side is formed in a stepped shape protruding in the inner direction A2. That is, in the step portion 43, the protruding portion 23 itself is bent in a step shape. By projecting the outer surface 23b side in the inner direction A2 by the distance D4, the front cabinet 2 can project the projection amount of the head 4b of the screw 4 from the projection 23 in the outer direction A1 (the projection amount corresponding to the thickness t of the head 4b). ) Is reduced.

  Further, as shown in FIG. 5, the protruding portion 23 has a rib shape extending in the depth direction from the frame portion 21 (see FIG. 3) together with the engaging portion 24. Here, in the vicinity of the fixed portion 42 in the protrusion 23, a notch 25 that facilitates bending deformation of the protrusion 23 toward the side A is provided. The notch portion 25 is an example of the “thickening portion” in the present invention. The notch 25 has a cut shape provided in the protrusion 23 so as to cut from the tip side between the protrusion 23 and the engagement portion 24. The notch 25 is formed so as to extend from the tip side of the protrusion 23 to the vicinity of the position where the step 43 is formed. As a result, the projecting portion 23 is configured so that the tip side portion from the stepped portion 43 including the fixing portion 42 is easily bent and deformed laterally by an external force in the axial direction (inward direction) when the screw 4 is tightened. Has been. The protruding portion 23 and the engaging portion 24 are formed so as to be connected continuously (integrally) on the root portion 41 side while being separated at the distal end side portion by the notch portion 25.

  As shown in FIGS. 4 and 5, the engaging portion 24 is engaged with the engaging convex portion 16 b of the rear frame 16 so as to regulate the rotational position shift of the front cabinet 2 when fastened by the screw 4. It is configured. That is, the engaging part 24 is arranged on the right side with respect to the direction (inner direction A2) toward the screw 4 and is configured to restrict the rotation (twist) of the front cabinet 2 along the rotation direction R of the screw 4. Yes. As shown in FIG. 6, the engaging portion 24 includes a hook 24 a that extends in the Y direction and protrudes in the inner direction A <b> 2 at the tip portion. On the other hand, the engaging convex part 16b of the rear frame 16 is formed so as to project in the outer direction A1. By engaging the engaging portion 24 (hook 24a) and the engaging convex portion 16b, the rotational displacement (relative to the rear frame 16) of the front cabinet 2 due to the external force in the rotational direction R around the axis of the screw 4 is restricted. Is done.

  With the above configuration, in the first embodiment, the width of the area (outer area of the display module 1) secured for fixing the front cabinet 2 with the screws 4 in the frame portion 21 is W. This width W is smaller than the maximum outer diameter d of the screw 4 (the outer diameter of the head 4b).

  Next, the operation of the television apparatus 100 according to the first embodiment will be described with reference to FIGS.

  Since the front cabinet 2 of the television apparatus 100 according to the first embodiment is formed by resin molding, there is a possibility that some variation in the outer diameter dimension occurs during manufacture. When the dimensional margin is reduced for narrowing the frame, the dimensional margin for the variation in the outer dimension is also reduced.

  On the other hand, in the first embodiment, the front cabinet 2 is fixed by the fixing portion 42 at the tip of the protrusion 23, and the notch 25 extending from the tip to a position near the step portion 43 is provided in the protrusion 23. As a result, the distal end portion of the protrusion 23 (the portion on the distal end side from the stepped portion 43) is bent and deformed, and the dimensional variation can be absorbed.

  That is, as shown in FIG. 7, when the front cabinet 2 is finished within a tolerance range than the design, the position of the inner surface 23 a in the fixing portion 42 is determined by the screw 4, so that the protruding portion 23 is outside the design. The state is shifted (a state in which the deviation D5 between the fixed portion 42 and the root portion 41 is larger than the interval D1 in FIG. 3). Also in this case, the front cabinet 2 is fixed in a state (distance D5) in which the tip side portion of the stepped portion 43 is bent and deformed and the projecting portion 23 is shifted outward from the design.

  On the other hand, as shown in FIG. 8, when the front cabinet 2 is finished to be smaller than the design within the tolerance range, the protruding portion 23 is displaced in the inner direction A2 from the design (the fixed portion 42 and the root portion 41 The deviation D6 is smaller than the interval D1 in FIG. Also in this case, the front cabinet 2 is fixed in a state (interval D6) where the tip side portion of the stepped portion 43 is bent and deformed and the protruding portion 23 is displaced in the inner direction A2 from the design. In addition, when the front cabinet 2 is small and thus has no space (a space corresponding to the width D1 and the depth D3, see FIG. 3) inside the root portion 41, the front cabinet 2 (protruding portion 23). Presses the liquid crystal cell 11 through the mold frame 12. On the other hand, in the first embodiment, since a space is formed on the inner side (A2 direction side) of the root portion 41, the front cabinet 2 is prevented from pressing the mold frame 12 even when dimensional variations occur. Is done.

  In the first embodiment, the following effects can be obtained.

  In 1st Embodiment, while providing the protrusion part 23 extended in the depth direction Y from the frame part 21 in the front cabinet 2 as mentioned above, the protrusion part 23 of the front cabinet 2 is set to the inner side direction (A2 direction) with the screw 4. By providing the fixing portion 42 that is fixed to the rear frame 16 so that the axial direction of the screw 4 can be directed in the width direction (A direction) of the frame portion 21, the screw 4 is arranged in the depth direction Y (front-rear direction). Unlike the case of fixing toward the head, it is not necessary to provide a space in the frame portion 21 that is larger than the outer diameter d of the head 4b of the screw 4. As a result, the front cabinet 2 can be fastened and fixed simply by securing a space with a small width W in the frame portion 21, so that the frame area of the front cabinet 2 can be narrowed.

  Further, in the first embodiment, as described above, the protruding portion 23 is provided inside the rear cabinet 3 and at a position between the outer peripheral wall portion 22 and the liquid crystal cell 11. Thereby, even in the configuration in which the screws 4 are attached in the A2 direction, the screws 4 need not be exposed to the outer surface of the front cabinet 2. That is, the front cabinet 2 has a function as a decorative plate of the display device, and the front surface on the display surface 11a side and the upper, lower, left, and right side surfaces have a great influence on the appearance design. There is an advantage that can be fixed. Furthermore, it is possible to prevent the screw 4 from being accidentally removed from the front cabinet 2.

  In the first embodiment, as described above, the fixing portion 42 is disposed at a position on the back side (Y2 direction side) from the liquid crystal cell 11 and is fixed to the rear frame 16 at a position on the back side from the liquid crystal cell 11. The part 42 is fixed. As a result, the screws 4 can be arranged at a position on the inner side (A2 direction side) so that the screws 4 overlap the liquid crystal cell 11 when viewed from the front (viewed from the Y direction). Can be further narrowed.

  Moreover, in 1st Embodiment, as mentioned above, the fixing | fixed part 42 is arrange | positioned with respect to the base part 41 of the protrusion part 23 in the position shifted | deviated to the A2 direction. As a result, even when the liquid crystal cell 11 is disposed close to the inside of the protruding portion 23 (base portion 41) for narrowing the frame, the amount of displacement of the base portion 41 is equal to the amount of deviation between the fixed portion 42 and the base portion 41. A space can be secured on the inner side (the liquid crystal cell 11 side). As a result, even when the outer dimensions of the front cabinet 2 vary due to a dimensional error during manufacturing, the projection 23 (the base portion 41) presses the liquid crystal cell 11 in the assembled state, causing display unevenness and the like. Can be prevented.

  Further, in the first embodiment, as described above, the protruding portion 23 is formed so as to extend linearly from the root portion 41 in the Y direction. Then, a stepped portion 43 that protrudes in the A2 direction toward the fixed portion 42 is formed in the protruding portion 23 at a position on the back side (Y2 direction side) from the arrangement position of the liquid crystal cell 11. Thereby, since the protrusion part 23 is linearly formed to the position on the back side from the liquid crystal cell 11, the space secured inside the base part 41 (the liquid crystal cell 11 side) can be maximized. .
