Two fixing claws 45 of the holder 41 are inserted into the wide portion of the L-shaped hole 313 from above the inclined portion 312. At this time, the holder 41 is arranged in a direction in which the pressing claw 43 is directed from the rear side to the front side. When the lower surface of the holder base 42 is pressed against the inclined portion 312, the lower protrusion 48 on the lower side of the thin portion 47 contacts the inclined portion 312, and the thin portion 47 is bent upward.

  When the holder 41 is moved to the front side in a state where the lower surface of the holder base 42 and the upper surface of the inclined portion 312 are in contact with each other, the tip of the fixing claw 45 enters the lower side of the inclined portion 312. An inclined portion 312 is sandwiched between the distal end portion of the fixing claw 45 and the pressing plate 46. Further, the lower protrusion 48 enters the round hole 314, and the holder 41 is fixed at a predetermined position. As described above, the holder 41 is attached to the inclined portion 312.

  The holder 41 is fixed to the inclined portion 312 by the same structure at the lower, right and left edges of the display panel 23, and the source substrate 25 or the gate substrate 27 is inserted between the presser claws 43 and the holder base 42. .

The source substrate 25 and the gate substrate 27 connected to the edge of the display panel 23 via the driver substrate 24 are inserted between the holding claw 43 of the holder 41 fixed to the inclined portion 312 and the holder base 42. As a result, it is possible to prevent the source substrate 25 and the gate substrate 27 from moving and disconnecting during transportation or use. That is, a high-definition display device 10 having a large number of circuit boards can be realized.

  The heat generated by the driver 29 is transmitted to the first heat radiating plate 51 or the second heat radiating plate 52 through the driver substrate 24. The first heat sink 51 and the second heat sink 52 are cooled by a cooling device such as a cooling fan provided inside the display device 10. The air heated by the first heat radiating plate 51 and the second heat radiating plate 52 flows out of the display device 10 from a large number of air holes provided on the upper surface and the back surface of the rear housing 19. As described above, the heat generated in the driver 29 is radiated to the outside of the display device 10 and the driver 29 is prevented from being overheated.

  According to the present embodiment, a large number of circuit boards can be arranged along the inclined portion 312 by using the holder 41 attached to the inclined portion 312 of the container 31. Therefore, it is possible to prevent the high-definition display device 10 having a large number of circuit boards from being enlarged except for the image display surface.

  The display device 10 is configured as a television receiver by mounting on the input board 14 a television receiver having an antenna terminal for connecting an antenna for television broadcasting and a tuner circuit for receiving radio waves for television broadcasting. be able to. A predetermined process is performed on the broadcast signal received by the television receiver, and the broadcast signal is separated into a video signal and an audio signal. An image is displayed on the display panel 23 based on the image signal. The audio signal is converted into sound by a speaker (not shown) or an external speaker connected via an audio output terminal and output. Note that an antenna for receiving a television broadcast may be mounted on the input board 14 instead of the antenna terminal.

  By using the display device 10 as a television receiver, a large number of circuit boards necessary for a high-definition television receiver such as 8K can be arranged along the inclined portion 312 of the container 31. Therefore, it is possible to prevent an increase in size of a portion other than the surface on which the video is displayed in the high-definition television receiver.
