(Configuration of source board)
The source substrate 202 corresponds to an electric component, and is provided with a signal processing circuit that generates a TFT drive signal according to an image signal and various processing circuits such as a timing controller (TCON: Timing Controller). Is.

As shown in FIG. 3, the source substrate 202 is arranged on the back side of the display panel 205 along the lower peripheral edge of the display panel 205, with the left-right direction as the longitudinal direction and the vertical direction as the lateral direction. It is a substantially rectangular substrate. The source driver 253 is connected to the source board 202 from below.

The source substrate 202 is supported from below by the elastic force of the flexible substrate constituting the source driver 253. The source substrate 202 is arranged at a position with respect to the display panel 205 according to the shape of the source driver 253. The position of the source substrate 202 is regulated by the intermediate member 203 as described later. In this embodiment, a configuration in which two source substrates 202 are arranged is illustrated, but the number of source substrates 202 is not limited to the illustrated example.

At least a part of the source substrate 202 is covered and protected by the substrate cover 211 fixed to the back side of the apparatus main body 201. As shown in FIG. 2, the substrate cover 211 has a substantially L-shaped cross-sectional shape and is located above and behind the source substrate 202. Although not shown, the substrate cover 211 is fixed to, for example, a heat spreader 244 or the like with screws or the like. The substrate cover 211 may be arranged so as to be in contact with the upper end portion of the source substrate 202, for example, whereby the position of the source substrate 202 can be restricted from above.

(Structure of intermediate members)
As shown in FIG. 2, the intermediate member 203 is arranged between a member such as the heat spreader 244 of the apparatus main body 201 and the source substrate 202. That is, the intermediate member 203 is arranged on the side of the device main body 201 with respect to the source substrate 202. The intermediate member 203 is formed of a sheet-shaped elastic member, more specifically, an insulating sheet, suppresses interference between the device main body 201 and the source substrate 202, and electrically connects the device main body 201 and the source substrate 202. Insulate to.

FIG. 4 is a plan view schematically showing a state in which the intermediate member 203 is unfolded. In FIG. 4, the X direction corresponds to the left-right direction in FIG. 1, and the Y direction orthogonal to the X direction corresponds to the up-down direction in FIG. As shown in FIGS. 2 and 4, the intermediate member 203 includes a fixing portion 231 fixed to the device main body portion 201 and an extending portion 232 extending from the fixing portion 231.

As shown in FIG. 4, the fixing portion 231 is formed in a rectangular shape with the X direction (left-right direction) as the longitudinal direction. The fixing portion 231 is provided with a notch at a position where the fixing angle 207 is provided. As shown in FIG. 2, the fixing portion 231 is fixed to the heat spreader 244 by, for example, an adhesive, and at least a part thereof is arranged between the apparatus main body portion 201 and the source substrate 202. The fixing portion 231 is formed in substantially the entire area of the heat spreader 244 in the left-right direction. That is, since the fixing portion 231 is arranged in front of the source substrate 202, it is possible to prevent the source substrate 202 from interfering with the heat spreader 244.

As shown in FIG. 4, the extending portion 232 extends from the fixing portion 231 along the Y direction. A plurality of extension portions 232 are provided at positions separated from each other along the X direction. By providing a plurality of extending portions 232 for one fixing portion 231, the assembling work can be simplified.

As shown in FIG. 2, the extending portion 232 is located between the facing portion 233 facing the source substrate 202 and the fixing portion 231 and the facing portion 233, and the display panel 205 and the source substrate 202 It is provided with a variable portion 234 that can be deformed into a shape corresponding to the relative position of the above. In the present embodiment, the facing portion 233 and the variable portion 234 are integrally formed as a part of the insulating sheet. The facing portion 233 is a part of the extending portion 232 including the end portion (tip portion) on the side opposite to the fixing portion 231 of the extending portion 232.

In the example shown in FIG. 2, the extending portion 232 is arranged so that the tip portion is held by the fixing angle 207 in a folded state. That is, the extending portion 232 extends upward from the fixed portion 231 and is folded back at the variable portion 234 in a direction opposite to the extending direction from the fixed portion 231. As a result, the facing portion 233 is arranged on the back surface side of the heat spreader 244 so that at least a part thereof faces the front surface of the source substrate 202. Further, the intermediate member 203 can be arranged in a smaller space as compared with the case where the intermediate member 203 is not folded back.

In the extending portion 232, the position of the opposing portion 233 with respect to the fixing portion 231 can be changed by deforming the variable portion 234. For example, even if the thickness dimension of the heat spreader 244 in the front-rear direction differs between different models, the facing portion 233 faces the source substrate 202 arranged at a position corresponding to the shape of the source driver 253 so as to approach or contact the source substrate 202. The position of the portion 233 can be adjusted. Further, since the variable portion 234 is formed of a sheet-like member, it can be deformed at an arbitrary position. Therefore, the degree of freedom in adjusting the position of the facing portion 233 can be improved.

As shown in FIG. 2, the extending portion 232 is formed with a first through hole 235, a second through hole 236, and an angle insertion hole 237. The fixing pin 206 is inserted into the first through hole 235 and the second through hole 236, and the fixing angle 207 is inserted into the angle insertion hole 237, whereby the extension portion 232 is positioned with respect to the device main body portion 201. And be retained.

As shown in FIG. 4, the first through hole 235 and the second through hole 236 are provided at positions separated from each other in the extension direction of the extension portion 232. For example, the first through hole 235 and the second through hole 236 are provided in the region corresponding to the variable portion 234. Further, the first through hole 235 and the second through hole 236 are provided at positions sandwiching the bent portion when the extending portion 232 is folded back and arranged.

FIG. 5 is a diagram schematically showing the periphery of the first through hole 235 of the extending portion 232. As shown in FIG. 5, the extension portion 232 is formed with a slit 501 continuous with the first through hole 235 from the outside to the inside of the first through hole 235. The extension portion 232 is formed with a slit 501 continuous with the first through hole 235 from the outside to the inside of the first through hole 235. The plurality of slits 501 are formed radially along the edge portion 502 of the first through hole 235.

FIG. 6 is a diagram schematically showing a cross section of the extending portion 232 and the fixing pin 206 inserted through the first through hole 235. The hole diameter 503 (see FIG. 5) of the first through hole 235 is smaller than the outer diameter (also referred to as pin diameter) 601 of the fixing pin 206. In such a configuration, since the fixing pin 206 is press-fitted into the first through hole 235, the fixing pin 206 can be inserted into the first through hole 235 and fixed to the first through hole 235. The change in the insertion position of the pin 206, that is, the change in the position of the extension portion 232 in the front-rear direction can be suppressed.

Further, in the present embodiment, since the edge portion 502 of the first through hole 235 is engaged with the groove portion 261, the change in the position of the extension portion 232 in the front-rear direction can be more preferably suppressed. Further, in the present embodiment, the hole diameter 503 of the first through hole 235 is smaller than the outer diameter (groove diameter) 602 of the groove portion 261 of the fixing pin 206. In such a configuration, as shown in FIG. 6, the edge portion 502 of the first through hole 235 is deformed by the slit 501 to press the inner surface of the groove portion 261 and is more firmly engaged with the groove portion 261. , The change in the position of the extension portion 232 can be more preferably suppressed.

The second through hole 236 is provided on the fixing portion 231 side of the first through hole 235. As shown in FIG. 2, the second through hole 236 is located closer to the proximal end side of the fixing pin 206 than the first through hole 235 when the fixing pin 206 is inserted.

The hole diameter of the second through hole 236 is substantially the same as the pin diameter 601 of the fixing pin 206, or larger than the pin diameter 601. Therefore, the insertion position of the second through hole 236 can be changed in the front-rear direction, whereby the relative position between the fixed portion 231 and the facing portion 233 can be changed. Therefore, regardless of the shape of the rear side of the apparatus main body 201, the relative position of the facing portion 233 can be changed so that the source substrate 202 is arranged at a predetermined position with respect to the display panel 205.

FIG. 7 is a diagram schematically showing a cross section of the display device 110 when the thickness dimension of the heat spreader 244 is smaller than that of FIG. 2. In the display device 110, a heat spreader 244 having a thickness corresponding to the amount of heat generated by the backlight 204 or the like may be arranged. For example, the amount of heat generated differs between a high-luminance backlight and a low-luminance backlight. In the example shown in FIG. 7, a backlight 204 having a lower brightness than the example shown in FIG. 2 is used, and a thinner heat spreader 244 is provided. When the source board 202 is fixed to the device main body such as the heat spreader 244 by the board holder, in order to arrange the source board 202 at a predetermined position with respect to the display panel 205, the board holder is changed according to the thickness of the heat spreader 244. There is a need. Further, it is necessary to change the length of the source driver 253 according to the distance between the source board 202 and the display panel 205 without changing the board holder. As described above, by using the board holder and the source driver according to the shape of the back surface of the apparatus main body 201, the parts cannot be shared between the models, and there is a possibility that the manufacturing efficiency is lowered.

On the other hand, in the present embodiment, as shown in FIG. 7, even when the thickness of the heat spreader 244 is different, that is, even when the distance between the source substrate 202 and the heat spreader 244 is different, the insertion position of the second through hole 236 is set. By changing the position, the folding position of the extending portion 232 can be changed, and the relative position between the fixed portion 231 and the facing portion 233 can be changed without changing the position of the facing portion 233. Therefore, parts can be shared between models, and manufacturing efficiency can be improved.

FIG. 8 is a perspective view schematically showing an example of the above-mentioned fixing angle 207. FIG. 9 is a diagram schematically showing a tip portion of an extension portion 232 in which a fixing angle 207 is inserted into an angle insertion hole 237. As shown in FIG. 8, the fixing angle 207 is formed with a constricted portion 801. The constricted portion 801 has a smaller dimension in the left-right direction of the main body portion 271 than the other portions. As shown in FIG. 9, the constriction portion 801 is inserted into the angle insertion hole 237. As a result, the fixing angle 207 holds a part of the extending portion 232, and in the present embodiment, the facing portion 233 including the end portion opposite to the fixing portion 231. Since the extension portion 232 is fixed to the device main body portion 201 at two locations, the fixing portion 231 side and the tip end side, the misalignment of the extension portion 232 is suppressed.

As shown in FIG. 9, the angle insertion hole 237 is formed at an end portion of the extending portion 232 opposite to the fixing portion 231. The extension portion 232 is formed with a notch 901 extending from the tip end portion of the extension portion 232 in the extension direction to the angle insertion hole 237, and a slit 902 continuous with the angle insertion hole 237 along the extension direction. To. The slit 902 can deform the tip of the extending portion 232, making it easier to insert the fixing angle 207 into the angle insertion hole 237.

The size of the main body 271 of the fixing angle 207 in the left-right direction is larger than the size of the angle insertion hole 237. As a result, the fixing angle 207 can hold the extending portion 232 at the forming position of the constricted portion 801 and can suppress the misalignment of the extending portion 232.

(Second Embodiment)
Next, the second embodiment will be described. It should be noted that the same points as in the first embodiment will be omitted below. The second embodiment differs from the first embodiment in that the intermediate member includes positioning portions that regulate the vertical and rear positions of the source substrate 202 (electrical components).

FIG. 10 is a plan view showing a state in which the intermediate member according to the second embodiment is unfolded. 11 and 12 are views showing an example of a schematic configuration of a cross section of the display device. The intermediate member 1000 includes a first positioning unit 1001 that defines a lower position of the source substrate 202, and a second positioning unit 1002 that defines an upper position and a rear position of the source substrate 202.

As shown in FIG. 10, the first positioning portion 1001 extends from the −Y side end portion (lower end in FIGS. 11 and 12) of the fixing portion 231. As shown in FIGS. 11 and 12, the first positioning portion 1001 is bent rearward and is arranged below the source substrate 202. The dimension of the first positioning portion 1001 in the extending direction may be a value larger than the maximum thickness value of the heat spreader. As a result, even if the relative positions of the fixing portion 231 and the source substrate 202 change according to the thickness of the heat spreader, the first positioning portion 1001 can be arranged below the source substrate 202.

As shown in FIG. 10, the second positioning portion 1002 extends from the upper end of the fixing portion 231. As shown in FIGS. 11 and 12, the second positioning portion 1002 is bent at two points according to the thickness of the heat spreader 244 and covers a part of the upper end portion of the source substrate 202. That is, the second positioning unit 1002 has an upper side portion 1101 located above the source substrate 202 and a rear side portion 1102 located rearward. The dimension of the second positioning portion 1002 in the extending direction (Y direction in FIG. 10) is a value obtained by adding the minimum dimension of the rear side portion 1102 to the maximum value of the thickness of the heat spreader 244. Thereby, even if the relative positions of the fixing portion 231 and the source substrate 202 change according to the thickness of the heat spreader 244, the second positioning portion 1002 can be arranged above and behind the source substrate 202.

In the second embodiment, the configuration in which the first positioning portion 1001 is bent at one place is illustrated, but a configuration in which the first positioning portion 1001 is bent at two places may be adopted as in the case of the second positioning portion 1002. Further, although the configuration in which the second positioning portion 1002 is bent at two places is illustrated, the configuration may be such that the second positioning portion 1002 is bent at one place.

(Third Embodiment)
Next, a third embodiment will be described. The third embodiment differs from the second embodiment in that the second positioning portion in the second embodiment is provided not in the fixed portion but in the extending portion. Further, the third embodiment is different from the first and second embodiments in that one extending portion is provided with respect to the fixed portion.

FIG. 13 is a plan view showing a state in which the intermediate member according to the third embodiment is unfolded. 14 and 15 are views showing an example of a schematic configuration of a cross section of a display device. 14 is a cross-sectional view at a position including the first positioning portion 1303 of FIG. 13, and FIG. 15 is a cross-sectional view at a position including the second positioning portion 1304 of FIG. The intermediate member 1300 includes a fixing portion 1301 and one extending portion 1302 extending in the Y direction from the fixing portion 1301. In such a configuration, since the area of the fixed portion 1301 can be reduced, the fixed portion 1301 can be arranged even in a smaller space, and the degree of freedom in design can be improved.

As shown in FIG. 13, the fixing portion 1301 has a substantially L-shape in a plan view and includes a first positioning portion 1303. The first positioning portion 1303 extends from the −Y side end of the fixing portion 1301 as in the second embodiment. The first positioning unit 1303 is bent rearward as shown in FIG. 14 and is arranged below the source substrate 202.

As shown in FIG. 13, the extending portion 1302 extends in the Y direction from a position different from that of the first positioning portion 1303 in the X direction (corresponding to the left-right direction). The extending portion 1302 includes an opposing portion 233 and a variable portion 234. A second positioning unit 1304 is provided.

As shown in FIG. 15, the second positioning portion 1304 is bent rearward with the extending portion 1302 folded back, and is located above the source substrate 202. The dimension of the second positioning portion 1304 in the extending direction is, for example, about the thickness of the source substrate 202. In the third embodiment, the second positioning portion 1304 is provided on the tip side of the first through hole 235 in the extending direction (Y direction), for example, on the facing portion 233. Therefore, since the second positioning portion 1304 is bent rearward from the position of the facing portion 233, the dimension of the second positioning portion 1304 can be set to a predetermined value regardless of the thickness of the heat spreader 244.

In the third embodiment, the first positioning portion 1303 is formed in the fixed portion 1301, but it may be provided in the extending portion 1302 in the same manner as the second positioning portion 1304. That is, the first positioning portion 1303 may be provided at a position corresponding to the lower end of the source substrate 202 of the facing portion 233.
